**The Techno Maestro's
Amazing Machine**

**Kohei Minato and the Japan Magnetic Fan Company**

*A maverick inventor's breakthrough electric motor uses
permanent magnets to make power -- and has investors
salivating*

**by John Dodd**

When we first got the call from an excited colleague
that he'd just seen the most amazing invention -- a magnetic motor
that consumed almost no electricity -- we were so skeptical that
we declined an invitation to go see it. If the technology was so
good, we thought, how come they didn't have any customers yet?

We forgot about the invitation and the company until several
months later, when our friend called again.

"OK," he said. "They've just sold 40,000 units to a major
convenience store chain. Now will you see it?"

In Japan, no one pays for 40,000 convenience store cooling fans
without being reasonably sure that they are going to work.

**The Maestro ~**

The streets of east Shinjuku are littered with the tailings of
the many small factories and workshops still located there --
hardly one's image of the headquarters of a world-class
technology company. But this is where we are first greeted
outside Kohei Minato's workshop by Nobue Minato, the wife of the
inventor and co-director of the family firm.

The workshop itself is like a Hollywood set of an inventor's
garage. Electrical machines, wires, measuring instruments and
batteries are strewn everywhere. Along the diagram-covered walls
are drill presses, racks of spare coils, Perspex plating and
other paraphernalia. And seated in the back, head bowed in
thought, is the 58-year-old techno maestro himself.

Minato is no newcomer to the limelight. In fact, he has been an
entertainer for most of his life, making music and producing his
daughter's singing career in the US. He posseses an oversized
presence, with a booming voice and a long ponytail. In short,
you can easily imagine him onstage or in a convertible cruising
down the coast of California -- not hunched over a mass of wires
and coils in Tokyo's cramped backstreets.

Joining us are a middle-aged banker and his entourage from
Osaka and accounting and finance consultant Yukio Funai. The
banker is doing a quick review for an investment, while the rest
of us just want to see if Minato's magnetic motors really work.
A prototype car air conditioner cooler sitting on a bench looks
like it would fit into a Toyota Corolla and quickly catches our
attention.

![](minato101.jpg)

**Seeing is Believing ~**

Nobue then takes us through the functions and operations of
each of the machines, starting off with a simple explanation of
the laws of magnetism and repulsion. She demonstrates the
"Minato Wheel" by kicking a magnet-lined rotor into action with
a magnetic wand.

Looking carefully at the rotor, we see that it has over 16
magnets embedded on a slant --  apparently to make Minato's
machines work, the positioning and angle of the magnets is
critical. After she kicks the wheel into life, it keeps
spinning, proving at least that the design doesn't suffer from
magnetic lockup.

She then moves us to the next device, a weighty machine
connected to a tiny battery. Apparently the load on the machine
is a 35kg rotor, which could easily be used in a washing
machine. After she flicks the switch, the huge rotor spins at
over 1,500 rpms effortlessly and silently. Meters show the power
in and power out. Suddenly, a power source of 16 watt or so is
driving a device that should be drawing at least 200 to 300
watts.

Nobue explains to us that this and all the other devices only
use electrical power for the two electromagnetic stators at
either side of each rotor, which are used to kick the rotor past
its lockup point then on to the next arc of magnets. Apparently
the angle and spacing of the magnets is such that once the rotor
is moving, repulsion between the stators and the rotor poles
keeps the rotor moving smoothly in a counterclockwise direction.
Either way, it's impressive.

Next we move to a unit with its motor connected to a generator.
What we see is striking. The meters showed an input to the
stator electromagnets of approximately 1.8 volts and 150mA
input, and from the generator, 9.144 volts and 192mA output. 1.8
x 0.15 x 2 = 540mW input and 9.144 x 0.192 = 1.755W out.

But according to the laws of physics, you can't get more out of
a device than you put into it. We mention this to Kohei Minato
while looking under the workbench to make sure there aren't any
hidden wires.

Minato assures us that he hasn't transcended the laws of
physics. The force supplying the unexplained extra power out is
generated by the magnetic strength of the permanent magnets
embedded in the rotor. "I'm simply harnessing one of the four
fundamental forces of nature," he says.

Although we learned in school that magnets were always bipolar
and so magnetically induced motion would always end in a locked
state of equilibrium, Minato explains that he has fine-tuned the
positioning of the magnets and the timing of pulses to the
stators to the point where the repulsion between the rotor and
the stator (the fixed outer magnetic ring) is transitory. This
creates further motion -- rather than a lockup. (See the sidebar
on page 41 for a full explanation).

![](minato40.jpg)

**Real Products ~**

Nobue Minato leads us to the two devices that might convince a
potential investor that this is all for real.

First, she shows us the cooling fan prototype that is being
manufactured for a convenience store chain's 14,000 outlets (3
fans per outlet). The unit looks almost identical to a
Mitsubishi-manufactured fan unit next to it, which is the unit
currently in wide use. In a test, the airflow from both units is
about the same.

The other unit is the car air conditioning prototype that
caught our eye as we came in. It's a prototype for Nippon Denso,
Japan's largest manufacturer of car air conditioners. The unit
is remarkably compact and has the same contours and size as a
conventional unit. Minato's manufacturing skills are clearly
improving.

![](minato45.jpg)

**The Banker and his Investment ~**

Minato has good reason to complain about Japan's social and
cultural uniformity. For years, people thought of him as an
oddball for playing the piano for a living, and bankers and
investors have avoided him because of his habit of claiming that
he'd discovered a breakthrough technology all by himself --
without any formal training.

However, the Osaka banker stands up after the lecture and
announces that before he goes, he will commit \100 million to
the investment pool.

Minato turns to us and smiles. We brought him good luck, and
this was his third investor in as many weeks to confirm an
interest.

**Bringing the Tech to the Table ~**

With the audience gone, we ask Minato what he plans to do to
commercialize the technology. His game plan is simple and clear,
he says. He wants to retain control, and he wants to
commercialize the technology in Japan first -- where he feels he
can ensure that things get done right. Why doesn't he go
directly to the US or China? His experiences in both countries,
he suggests, have been less than successful. "The first stage is
critical in terms of creating good products and refining the
technology. I don't want to be busy with legal challenges and IP
theft while doing that."

Still, the export and licensing of the technology are on his
agenda, and Minato is talking to a variety of potential partners
in other countries.

Whereas another inventor might be tempted to outsource
everything to a larger corporation, part of what drives Minato
is his vision of social justice and responsibility. The 40,000
motors for the convenience store chain are being produced by a
group of small manufacturers in Ohta-ku and Bunkyo-ku, in the
inner north of Tokyo -- which is becoming a regional rust belt.
Minato is seized with the vision of reinvigorating these small
workshops that until the 80s were the bedrock of Japan's
manufacturing and economic miracle. Their level of expertise
will ensure that the quality of the motors will be as good as
those from any major company.

![](minato65.jpg)

**International Prep ~**

Despite his plan to do things domestically first, Minato is
well prepared for the international markets. He is armed with
both six years of living and doing business in Los Angeles in
the early 90s -- and with patent protection for over 48
countries. His is hardly a provincial perspective.

His US experience came after playing the piano for a living for
15 years. He began tinkering with his invention in the mid-70s.
The idea for his magnetic motor design came from a burst of
inspiration while playing the piano.

But Minato decided to drop everything in 1990 to help his
daughter Hiroko, who at the age of 20 decided that she wanted to
be a rhythm and blues star in the US. Minato is a strong
believer in family: If Hiroko was going to find fame and fortune
in the US, Dad had better be there to help manage her. He
suceeded in helping Hiroko to achieve a UK dance chart number
one hit in 1995.

In 1996 Minato returned to Japan and his magnetic motor
project. The following year he displayed his prototypes to
national power companies, government officials and others at a
five-day conference in Mexico City. Interest was palpable, and
Minato realized that his invention might meet a global need for
energy-saving devices.

Subsequent previews and speeches in Korea and Singapore further
consolidated his commitment to bringing the invention to
fruition, and he was able to bring in several early-stage
investors.

During the late 90s, Minato continued to refine his prototypes.
He also stayed in constant contact with his lawyer, registering
patents in major countries around the world. Through his
experiences in the US he realized that legal protection was
critical, even if it meant delaying release of the technology by
a couple of years.

Ironically, by the time he'd won patents in 47 countries, the
Japanese patent office turned him down on the grounds that "[the
invention] couldn' t possibly work" and that somehow he was
fabricating the claims.

But a few months later they were forced to recant their
decision after the US patent office recognized his invention and
gave him the first of two patents. As Minato notes: "How typical
of Japan's small-minded bureaucrats that they needed the
leadership of the US to accept that my invention was genuine."

By 2001, the Minatos had refined their motors and met enough
potential investors to enter into a major international
relationship, initially with a Saudi company, to be followed
thereafter by companies in the US and elsewhere.

However, fate dealt the investors and Minato's business a
serious blow when the World Trade Center was attacked in New
York. The Saudis retreated, and Minato's plans fell back to
square one.

Now Minato is once again ready to move. With the first order in
the works and more orders pending successful prototypes, he has
decided that investors don't have to be primary partners. He is
actively accepting inquiries from corporate investors who can
bring strategic advantages and corporate credibility with them.
His company, Japan Magnetic Fan, will make a series of
investment tie-up announcements in the first and second quarters
of 2004.

![](minato98.jpg)

**Implications ~**

Minato's motors consume just 20 percent or less of the power of
conventional motors with the same torque and horse power. They
run cool to the touch and produce almost no acoustic or
electrical noise. They are significantly safer and cheaper (in
terms of power consumed), and they are sounder environmentally.

The implications are enormous. In the US alone, almost 55
percent of the nation's electricity is consumed by electric
motors. While most factory operators buy the cheapest motors
possible, they are steadily being educated by bodies like NEMA
(National Electrical Manufacturers Association) that the costs
of running a motor over a typical 20-year lifespan comprise a
purchase price of just 3 percent of the total, and electricity
costs of 97 percent. It is not unusual for a $2,000 motor to
consume $80,000 of electricity (at a price of .06 cents per
kilowatt hour).

Since 1992, when efficiency legislation was put into place at
the US federal level, motor efficiency has been a high priority
-- and motors saving 20 percent or so on electrical bills are
considered highly efficient. Minato is about to introduce a
motor which saves 80 percent, putting it into an entirely new
class: The $80,000 running cost will drop to just $16,000. This
is a significant savings when multiplied by the millions of
motors used throughout the USA and Japan -- and eventually,
throughout the world.

![](minato76.jpg)

**The Devices ~**

Minato's invention and its ability to use remarkably less power
and run without heat or noise make it perfect for home
appliances, personal computers, cellphones (a miniature
generator is in the works) and other consumer products.

The magnetic motor will be cheaper than a standard motor to
make, as the rotor and stator assemblies can be set into plastic
housings, due to the fact that the system creates very little
heat. Further, with the motor's energy efficiency, it will be
well suited for any application where a motor has limited energy
to drive it. While development is still focused on replacing
existing devices, Minato says that his motor has sufficient
torque to power a vehicle.

With the help of magnetic propulsion, it is feasible to attach
a generator to the motor and produce more electric power than
was put into the device. Minato says that average efficiency on
his motors is about 330 percent.

Mention of Over Unity devices in many scientific circles will
draw icy skepticism. But if you can accept the idea that
Minato's device is able to create motion and torque through its
unique, sustainable permanent magnet propulsion system, then it
makes sense that he is able to get more out of the unit than he
puts in in terms of elctrical power. Indeed, if the device can
produce a surplus of power for longer periods, every household
in the land will want one.

"I am not in this for the money," Minato says. "I have done
well in my musical career, but I want to make a contribution to
society -- helping the backstreet manufacturers here in Japan
and elsewhere. I want to reverse the trends caused by major
multinationals. There is a place for corporations. But as the
oil industry has taught us, energy is one area where a
breakthrough invention like this cannot be trusted to large
companies."

Minato was once close to making a deal with Enron. But today,
he is firmly on a mission to support the small and the
independent -- and to go worldwide with them and his amazing
machine. "Our plan is to rally smaller companies and pool their
talent, and to one day produce the technology across a wide
range of fields."

**US Patent # 4,751,486**

**(Cl. 335/272)**

**Magnetic Rotation Apparatus**

(June 14. 1998)

**Kohei Minato**

**Abstract ---** The magnetic rotation apparatus of the
present invention has first and second rotors rotatably
supported and juxtaposed. The first and second rotors are
connected so as to be rotatable in opposite directions in a
cooperating manner. A number of permanent magnets are arranged
on a circumferential portion of the first rotor at regular
intervals, and just as many permanent magnets are arranged on a
circumferential portion of the second rotor at regular
intervals. Each permanent magnet has one magnetic polarity
located radially outward from the rotors, and has the other
magnetic polarity located radially inward toward the rotors. The
polarity of each permanent magnet, which is located radially
outward from the rotors, is identical. When the first and second
rotors are rotated in a cooperating manner, the phase of
rotation of the permanent magnets of one rotor is slightly
advanced from that of the permanent magnets of the other rotor.
One of the permanent magnets of one rotor is replaced with the
electromagnet. The radially outward polarity of the
electromagnet can be changed by reversing the direction in which
a current is supplied to the electromagnet.

***Claims ~*** [ Claims not included here ]

***Description***

**TECHNICAL FIELD**

The present invention relates to a magnetic rotation apparatus
in which a pair of rotors are rotated by utilizing a magnetic
force.

**BACKGROUND ART**

An electromotor is well known as a rotation apparatus utilizing
a magnetic force. For example, an AC electromotor comprises a
rotor having a coil, a stator surrounding the rotor, and a
plurality of electromagnets, disposed on the stator, for
generating a rotating magnetic field. An electric power must be
constantly supplied to the electromagnets in order to generate
the rotating magnetic field and keep the rotor rotating, i.e.,
an external energy, or electric energy, is indispensable for the
rotation of the rotor.

Under the circumstances, a magnetic rotation apparatus, which
employs permanent magnets in lieu of electromagnets and can
rotate a rotor only by a magnetic force of the permanent
magnets, is highly desirable.

The present application proposes a magnetic rotation apparatus
which comprises a pair of rotors rotatable in opposite
directions in a cooperating manner, and a plurality of permanent
magnets stationarily arranged at regular intervals on the
peripheral portion of each rotor. One end portion of each
permanent magnet of both rotors, which has the same polarity, is
located radially outward of the rotors. When the two rotors are
rotated in a cooperating fashion, a permanent magnet on one
rotor and a corresponding permanent magnet on the other, which
form a pair, approach and move away from each other
periodically. In this case, the phase of rotation of the magnet
on one rotor advances a little from that of the corresponding
magnet on the other rotor. When the paired permanent magnets
approach each other, magnetic repulsion causes one rotor to
rotate. The rotation of one rotor is transmitted to the other
rotor to rotate the same. In this manner, other pairs of magnets
on both rotors sequentially approach each other, and magnetic
repulsion occurs incessantly. As a result, the rotors continue
to rotate.

In the above apparatus, in order to stop the rotation of the
rotors, a brake device is required. If an ordinary brake device
is mounted on the magnetic rotation apparatus, the entire
structure of the apparatus becomes complex, and a driving source
for the brake device must be provided separately.

The present invention has been developed in consideration of
the above circumstances, and its object is to provide a magnetic
rotation apparatus including a brake device for suitably
stopping the rotation of rotors.

**DISCLOSURE OF THE INVENTION**

The magnetic rotation apparatus of the present invention is
provided with magnetic force conversion means which is
substituted for at least one pair of permanent magnets of the
paired rotors. In a normal state, the magnetic force conversion
means causes a magnetic repulsion, as in the other pairs of
permanent magnets. When it is intended for the rotors to stop,
the magnetic force conversion means causes a magnetic attraction
force. Since a magnetic attraction force can be produced between
the rotors at any time, the magnetic attraction force serves to
stop the rotors. The brake device constituted by the magnetic
force conversion means differs from an ordinary brake device
which forcibly stops a pair or rotors by using a frictional
force. In the brake device of this invention, by converting a
magnetic repulsion force to a magnetic attraction force, the
rotors can be braked in the state that the movement of the
rotors is reduced. Thus, the rotors can be stopped effectively.

**BEST MODE OF CARRYING OUT THE INVENTION**

FIG. 1 shows a magnetic rotation apparatus embodying the
present invention. The magnetic rotation apparatus has frame 1.
Frame 1 is provided with a pair of rotation shafts 2 which
extend vertically and in parallel to each other. Shafts 2 are
located at a predetermined distance from each other. Upper and
lower ends of each shaft 2 are rotationally supported on frame 1
via bearing 3.

First rotor 4a is mounted on one of rotation shafts 2, second
rotor 4b is mounted on the other rotation shaft 2. First and
second rotors 4a and 4b are arranged on the same level. Rotors
4a and 4b have similar structures. For example, each rotor 4a
(4b) comprises two ring-shaped plates 5 which are spaced apart
from each other in the axial direction of the rotation shaft 2.

Gears 6a and 6b made of synthetic resin are, as cooperating
means, attached to lower surfaces of first and second rotors 4a
and 4b. The diameters of gears 6a and 6b are identical but
larger than those of rotors 4a and 4b. Gears 6a and 6b mesh with
each other. First and second rotors 4a and 4b are thus rotatable
in opposite directions in a cooperating manner. In FIG. 1,
reference numeral 7 indicates support arms for supporting first
and second rotors 4a and 4b.

For example, 16 magnets are arranged at regular intervals on a
peripheral portion of first rotor 4a. These magnets are secured
between two ring-shaped plates 5. In this embodiment, among the
16 magnets, one is electromagnet 9a (see FIG. 2), and the others
are permanent magnets 8a. FIG. 2 shows only some of permanent
magnets 8a.

As shown in FIG. 3, permanent magnet 8a comprises case 10, and
a plurality of rod-like ferromagnetic members 11 housed in case
10. Ferromagnetic member 11 is, for example, a ferrite magnet.
Ferromagnetic members 11 of each permanent magnet 8a are
arranged such that ferromagnetic members 11 have the same
polarity at one end. In first rotor 4a, for example, an
N-polarity end portion of each permanent magnet 8a faces
radially outward, and an S-polarity end portion of magnet 8a
faces radially inward. As shown in FIG. 2, when each permanent
magnet 8a is located between two shafts 2, angle C formed by
longitudinal axis A of magnet 8a and imaginary line B connecting
two shafts 2 is, for example, set to 30.degree. C. On the other
hand, electromagnet 9a is, as shown in FIG. 4, constituted by
U-shaped iron core 12, and coil 13 wound around core 12.
Electromagnet 9a is arranged such that both N- and S-polarity
end portions face radially outward of first rotor 4a, and the
above-mentioned angle C is formed, similarly to the case of
permanent magnet 8a.

The same number of permanent magnets (8b,9b) as the total
number of all permanent magnets and electromagnet (8a,9a) of
first rotor 4a are secured on a peripheral portion of second
rotor 4b at regular intervals. In FIG. 2, when first and second
rotors 4a and 4b are rotated in opposite directions, each
permanent magnet of second rotor 4b periodically moves toward
and away from the corresponding one of the magnets (8a,9a) of
first rotor 4a.

The permanent magnets (8b,9b) of second rotor 4b will now be
described in greater detail. Permanent magnets 8b of second
rotor 4b, which periodically move toward and away from permanent
magnets 8a of first rotor 4a in accordance with the rotation of
rotors 4a and 4b, have a structure similar to that of permanent
magnets 8a of first rotor 4a. The polarity of that end portion
of each permanent magnet 8b which is located radially outward
from second rotor 4b, is identical with that of the end portion
of each permanent magnet 8a of first rotor 4a. That is, the
radially outward portion of each permanent magnet 8b has an
N-polarity.

Permanent magnet 9b of second rotor 4b, which periodically
moves toward and away from electromagnet 9a of first rotor 4a,
has a structure shown in FIG. 4. Permanent magnet 9b has a
structure similar to that of permanent magnets 8a. Both
polarities of electromagnet 9a face radially outward from first
rotor 4a. Permanent magnet 9b has two different polarities which
face radially outward from second rotor 4b and correspond to
both polarities of electromagnet 9a.

As shown in FIG. 2, when each permanent magnet 8b,9b is located
between two rotation shafts 2, angle E formed by longitudinal
axis D of the magnet (8b,9b) and imaginary line B connecting two
shafts 2 is, for example, set to 56.degree. C. In addition, when
rotors 4a and 4b are rotated in opposite directions, as shown by
arrows, the magnets (8a,9a) of first rotor 4a move a little
ahead of the corresponding permanent magnets (8b,9b) of second
rotor 4b, in a region in which both magnets (8a,9a; 8b,9b)
approach one another. In other words, the phase of rotation of
the magnets (8a,9a) of first rotor 4a advances by a
predetermined angle in relation to the permanent magnets (8b,9b)
of second rotor 4b.

As shown in FIG. 4, electromagnet 9a of first rotor 4a is
electrically connected to drive circuit 14. Drive circuit 14
includes a power source for supplying an electric current to
coil 13 of electromagnet 9a. While rotors 4a and 4b rotate,
drive circuit turns on electromagnet 9a upon receiving a signal
from first sensor 15 only when electromagnet 9a and permanent
magnet 9b are in a first region in which they periodically
approach each other. First sensor 15 is an optical sensor
comprising a light-emitting element and a light-receiving
element. As shown in FIG. 1, first sensor 15 is attached to a
portion of frame 1 above first rotor 4a. First sensor 15 emits
light in a downward direction. The light is reflected by
reflection plate 16 projecting radially inward from the inner
edge of first rotor 4a. First sensor 15 receives the reflected
light, and feeds a signal to drive circuit 14. Thus, drive
circuit 14 turns on electromagnet 9a.

The circumferential length of reflection plate 16 is equal to
that of the above-mentioned first region. When magnets 9a and 9b
enter the first region, first sensor 15 is turned on, and when
they leave the first region, first sensor 15 is turned off. When
drive circuit 14 receives a signal from first sensor 15, it
excites electromagnet 9a such that both polarities of
electromagnet 9a correspond to those of permanent magnet 9b of
second rotor 4b.

Drive circuit 14 is electrically connected to switching circuit
17. When brake switch 18 is operated, switching circuit 17
reverses the direction in which an electric current is supplied
to electromagnet 9a. When the current supplying direction of
drive circuit 14 is reversed, drive circuit 14 excites
electromagnet 9a only in a time period in which drive circuit 14
receives a signal from second sensor 19. Second sensor 19 has a
structure similar to that of first sensor 15, and is attached to
frame 1 so as to be located closer to the center of rotor 4a
than first sensor 15. Reflection plate 20, which corresponds to
the position of second sensor 19, is formed integral to an inner
edge portion of reflection plate 16. As shown in FIG. 2,
compared to reflection plate 16, reflection plate 20 extends in
rotational direction of first rotor 4a, indicated by the arrow.

The operation of the above-described magnetic rotation
apparatus will now be explained with reference to FIG. 5.

In FIG. 5, rotation shaft 2 of first rotor 4a is denoted by 01,
and rotation shaft 2 of second rotor 4b is denoted by 02. Only
the radially outward polarity, that is, N-polarity, of the
magnets of rotors 4a and 4b is shown, for the sake of
convenience. Although electromagnet 9a and permanent magnet 9b
have both polarities located radially outward, only the
N-polarity thereof is shown.

When first and second rotors 4a and 4b are put in a position
shown in FIG. 5, magnetic pole Nb1 of one permanent magnet of
second rotor 4b is located in a line connecting shafts 01 and
02. In this case, polarity Na1 of first rotor 4a, which is
paired with polarity Nb1, is a little advanced from polarity Nb1
in the rotational direction of first rotor 4a. For example, as
shown in FIG. 5, magnetic pole Na1 is advanced from polarity Nb1
by an angle of X.degree.. Polarities Na1 and Nb1 exert repulsion
force F1 upon each other along line L. Supposing that an angle,
formed by line M, which is drawn from shaft 01 perpendicularly
to line L, and the line connecting shafts 01 and 02 is
represented by Y, and that the length of line K is represented
by R, torques Ta1 and Tb1 caused by repulsion force F1 to rotate
first and second rotors 4a and 4b can be given by:

Ta1=F1.multidot.R.multidot.cos (Y-X)

Tb1=F1.multidot.R.multidot.cos Y

Since cos (Y-X)>cos Y, Ta1>Tb1.

As shown in FIG. 5, since magnetic pole Na1 is advanced from
magnetic pole Nb1 by angle X.degree., first rotor 4a receives a
greater torque than second rotor 4b. Thus, first rotor 4a
forwardly rotates in the direction of the arrow in FIG. 5.

Mention is now made of paired magnets of rotors 4a and 4b in
the vicinity of magnetic poles Na1 and Nb1. Magnetic poles Nan
and Nan-1 of first rotor 4a are advanced ahead of magnetic pole
Nal in the rotational direction. Magnetic poles Nan and Nan-1
receive a torque produced by a repulsion force acting between
magnetic poles Nan and Nan-1 and corresponding magnetic poles
Nbn and Nbn-1. In FIG. 5, magnetic poles Nan and Nan-1 receive a
smaller torque, as they rotate farther from the location of
magnetic pole Na1. It is well known that a torque of first rotor
4a, which is caused by a repulsion force acting on magnetic
poles Nan and Nan-1, is decreased in inverse proportion to the
square of the distance between paired magnetic poles Na and Nb.

Magnetic poles Na2 and Na3, behind magnetic pole Na1, receive a
torque which tends to rotate rotor 4a in the reverse direction.
This torque is considered to be counterbalanced with the torque
acting on magnetic poles Nan and Nan-1.

In FIG. 5, attention should be paid to the region of magnetic
poles Na1 and Na2. As first rotor 4a forwardly rotates, the
direction in which a torque applies to magnetic pole Na2, is
changed from the reverse direction to the forward direction,
before magnetic pole Na2 reaches the position of magnetic pole
Na1. The torque for forwardly rotating rotor 4a is larger than
that for reversely rotating rotor 4a. Therefore, first rotor 4a
is easily rotated in the direction shown in FIG. 2.

Second rotor 4b is considered to receive a torque in a
direction reverse to the direction shown in FIG. 2, as seen from
the description of first rotor 4a. It is obvious that second
rotor 4b receives a maximum torque at the position of magnetic
pole Nb1. As seen from the above formula, torque Tb1 applied to
second rotor 4b in a direction reverse to that denoted by the
arrow is smaller than torque Ta1 applied to first rotor 4a in
the forward direction. The rotation of first rotor 4a is
transmitted to second rotor 4b through gears 6a and 6b. By
determining the relationship between the strengths of torques
Ta1 and Tb1, second rotor 4b is thus rotated in a direction
reverse to the rotational direction of first rotor 4a, against
the torque applied to second rotor in the direction. As a
result, first and second rotors 4a and 4b are kept rotating,
since a torque for rotating rotors 4a and 4b in a cooperating
manner is produced each time magnetic poles Na of first rotor 4a
pass across the line connecting shafts 01 and 02.

In a diagram shown in the right part of FIG. 5, a solid line
indicates a torque applied to first rotor 4a, and a broken line
indicates a torque applied to second rotor 4b. The ordinate
indicates a distance between each magnetic pole and the line
connecting shafts 01 and 02 of rotors 4a and 4b. The first
region in which electromagnet 9a of first rotor 4a is turned on
is set in a range of Z during which a torque is applied to first
rotor 4a in the forward direction.

In order to stop the cooperative rotation of rotors 4a and 4b,
brake switch is turned on to operate switching circuit 17. Thus,
the direction in which drive circuit 14 supplies a current to
electromagnet 9a is reversed. The polarities of electromagnet 9a
are reversed. The torque applied to electromagnet 9a in the
forward direction is stopped. When electromagnet 9a approaches
permanent magnet 9b, a magnetic attract:on force is produced. As
a result, the rotation of rotors 4a and 4b is effectively slowed
down and stopped. Since the second region, in which
electromagnet 9a is excited, is larger than the first region, a
large braking force can be obtained from a magnetic attraction
force.

In the above embodiment, since electromagnet 9a is excited only
in a specific region, a large electric power is not required. In
addition, since electromagnet 9a rotates and brakes rotors 4a
and 4b, a braking mechanism for a magnetic rotation apparatus
can be obtained without having to make the entire structure of
the apparatus complex.

The present invention is not restricted to the above
embodiment. With the exception of the paired electromagnet and
permanent magnet, all permanent magnets of the rotors are
arranged such that their end portions of the same polarity face
radially outward from the rotors. However, it is possible that
the polarities of the radially outward end portions of the
permanent magnets are alternately changed. Namely, it should
suffice if the polarities of the radially outward end portions
of the first rotor are identical to those of the corresponding
radially outward end portions of the second rotor. The magnets
may have different magnetic forces. Furthermore, an electric
power for exciting the electromagnet can be derived from the
rotation of the rotors or from the revolving magnetic field of
the permanent magnet.

Angles C and E are not restricted to 30.degree. and 56.degree..
They may be freely determined in consideration of the strength
of the magnetic force of the permanent magnet, a minimum
distance between adjacent magnets, angle x, and the like. The
number of magnets of the rotor is also freely chosen.

**Industrial Applicability ~**

As described above, the magnetic rotation apparatus of the
present invention can be used as a driving source in place of an
electric motor, and as an electric generator.

***Description***

**BACKGROUND OF THE INVENTION**

**1. Field of the Invention**

The present invention relates to a magnetic rotating apparatus,
and more particularly, to a magnetic rotating apparatus which
utilizes repulsive forces produced between a permanent magnet
and an electromagnet.

**2. Description of the Prior Art**

In a conventional electric motor, an armature as a rotor
consists of turns of wires, and electric field as a stator
consists of a permanent magnet. In such the conventional
electric motor, however, current must be usually supplied to
windings of the armature which is rotated. When the current is
supplied, heat is generated, which gives rise to the problem
that not much driving force is efficiently generated. This, in
turn, gives wise to the problem that the magnetic forces cannot
be efficiently obtained from the permanent magnet.

In addition, in the conventional electric motor, since the
armature is so constructed as consisting of the windings, the
moment of inertia cannot be made very high, so that enough
torque cannot be obtained.

To overcome the above-described problems of such the
conventional electric motor, the inventor proposed, in Japanese
Patent Publication No. 61868/1993 (U.S. Pat. No. 4,751,486) a
magnetic rotating apparatus in which a plurality of the
permanent magnets are disposed along the two rotors,
respectively, at a predetermined angle, and in which an
electromagnet is disposed at one of the rotors.

In a generally constructed conventional electric motor, there
is a limit as to how much the efficiency of energy conversion
can be increased. In addition, the torque of the electric motor
cannot be made high enough. For the above reasons, hitherto,
various improvements have been made on existing electric motors,
without any success in producing an electric motor so
constructed has providing satisfactory characteristics.

In the magnetic rotating apparatus disclosed in Japanese Patent
Publication No. 6868/1993 (U.S. Pat. No. 4,751,486) a pair of
rotors is rotated. Therefore, it is necessary for each of the
rotors to have high precision, and in addition, measures must be
taken for easier rotation control.

**SUMMARY OF THE INVENTION**

In view of the above-described problems, the object of the
present invention is to provide a magnetic rotating apparatus in
which rotational energy can be efficiently obtained from the
permanent magnet with a minimum amount of electrical energy, and
in which rotation control can be carried out relatively easily.

According to one aspect of the present invention, there is
provided a magnetic rotating apparatus comprising a rotating
shaft; a rotor which is fixed to the rotating shaft and which

the direction of rotation, and a plurality of magnetic poles of
the other (or second) polarity type arranged along an inner
peripheral surface, with each pair of corresponding magnetic
poles of one and the other polarities obliquely arranged with
respect to a radial line; electromagnet means, which is disposed
facing this rotor, for developing a magnetic field which faces
the magnetic field of the permanent magnet means of the rotor
and detecting means for detecting rotating position of the rotor
to allow the electromagnet means to be energized.

According to another aspect of the present invention, there is
provided a magnetic rotating apparatus comprising a rotating
shaft a rotor which is fixed to the rotating shaft and which has
disposed thereon a plurality of permanent magnets and balancers
for balancing rotation, the permanent magnets being disposed
such that one magnetic polarity type is arranged along an outer
peripheral surface in the direction of rotation and the other
magnetic polarity type arranged along an inner peripheral
surface, with each pair of corresponding magnetic poles of one
and the other polarities obliquely arranged with respect to a

rotor, for developing a magnetic field which produces the other
magnetic polarity type on the facing surface; and energizing
means for intermittently energizing the electromagnet means from
where the leading permanent magnet, based on the rotation of the
rotor, passes the facing surface of the electromagnet in the
direction of rotation.

According to still another aspect of the present invention,
there is provided magnetic rotating apparatus comprising a
rotating shaft; a first rotor which is fixed to the rotating
shaft and which has disposed thereon permanent magnet means and
means for balancing rotation, the permanent magnet means being
disposed such that a plurality of magnetic poles of the second

with each pair of corresponding magnetic poles of one and the
other polarities obliquely arranged with respect to a radial
line; a second rotor which rotates along with the first rotor

**DESCRIPTION OF THE PREFERRED EMBODIMENTS**

The magnetic field developed by an electromagnet means and that
of a permanent magnet means of a rotor repel each other. In
addition, the magnetic field of the permanent magnet means is
flattened by the magnetic fields of other nearby permanent
magnets and electromagnet means. Therefore, a torque is produced
therebetween to efficiently rotate the rotor. Since the rotor
has a high inertial force, when the rotor starts rotating, its
speed increases by the inertial force and the turning force.

A magnetic rotating apparatus related to one embodiment of the
present invention will be described with reference to the
following drawings.

FIGS. 1 and 2 are schematic diagrams of a magnetic rotating
apparatus related to one embodiment of the present invention. In
the specification, the term "magnetic rotating apparatus" will
include an electric motor, and from its general meaning of
obtaining turning force from the magnetic forces of permanent
magnets, it will refer to a rotating apparatus utilizing the
magnetic forces. As shown in FIG. 1, in the magnetic rotating
apparatus related to one embodiment of the present invention, a
rotating shaft 4 is rotatably fixed to a frame 2 with bearings
5. To the rotating shaft 4, there are fixed a first magnet rotor
6 and a second magnet rotor 8, both of which produce turning
forces and a rotated body 10, which has mounted therealong a
plurality of rod-shaped magnets 9 for obtaining the turning
forces as energy. They are fixed in such a manner as to be
rotatable with the rotating shaft 4. At the first and second
magnet rotors 6 and 8, there are provided, as will be described
later in detail with reference to FIGS. 1 and 2, a first
electromagnet 12 and a second electromagnet 14 respectively are
energized in synchronism with rotations of the first and second
magnet rotors 6 and 8, both of which face each other and are
each disposed in a magnetic gap. The first and second
electromagnets 12 and 14 are respectively mounted to a yoke 16,
which forms a magnetic path.

As shown in FIG. 3, the first and second magnet rotors 6 and 8
each have disposed on its disk-shaped surface a plurality of
tabular magnets 22A through 22H for developing a magnetic field
for generating the turning forces and balancers 20A through 20H,
made of non-magnetic substances, for balancing the magnet rotors
6 and 8. In the embodiments, the first and second magnet rotors
6 and 8 each have disposed along the disk-shaped surface 24 at
equal intervals the eight tabular magnets 22A through 22H along
half of the outer peripheral area and +the eight balancers 20A
through 20H along the other half of the outer peripheral area.

As shown in FIG. 3, each of the tabular magnets 22A through 22H
are disposed so that its longitudinal axis 1 makes an angle D
with respect to a radial axis line 11 of the disk-shaped surface
24. In the embodiment, an angle of 30 degrees and 56 degrees
have been confirmed for the angle D. An appropriate angle,
however, can be set depending on the radius of the disk-shaped
surface 24 and the number of tabular magnets 22A through 22H to
be disposed on the disk-shaped surface 24. As illustrated in
FIG. 2, from the viewpoint of effective use of the magnetic
field, it is preferable that the tabular magnets 22A through 22H
on the first magnet rotor 6 are positioned so that their N-poles
point outward, while the tabular magnets 22A through 22H on the
second magnet rotor 8 are positioned so that their S-poles point
outward.

Exterior to the first and second magnet rotors 6 and 8, the
first and second electromagnets 12 and 14 are disposed facing
the first and second magnet rotors 6 and 8 respectively in the
magnetic gap. When the first and second electromagnets 12 and 14
are energized, they develop a magnetic field identical in
polarity to the their respective tabular magnets 22A through 22H
so that they repel one anther. In other words, as shown in FIG.
2, since the tabular magnets 22A through 22H on the first magnet
rotor 6 have their N-poles facing outwards, the first
electromagnet 12 is energized so that the side facing the first
magnet rotor 6 develops an N-polarity. In a similar way, since
the tabular magnets 22A through 22H on the second magnet rotor 8
have their S-poles facing outwards, the second electromagnet 14
is energized so that the side facing the tabular magnets 22A
through 22H develops a S-polarity. The first and second
electromagnets 12 and 14, which are magnetically connected by
the yoke 16, are magnetized so that the sides facing their
respective magnet rotors 6 and 8 are opposite in polarity with
respect to each other. This means that the magnetic fields of
the electromagnets 12 and 14 can be used efficiently.

A detector 30, such as microswitch, is provided to either one
of the first magnet rotor 6 or second magnet rotor 8 to detect
the rotating position of the magnet rotors 6 and 8. That is, as
shown in FIG. 3, in a rotational direction 32 of the tabular
magnets 22A through 22H, the first and the second magnet rotors
6 and 8 are respectively energized when the leading tabular 22A
has passed. In other words, in the rotational direction 32, the
electromagnet 12 or 14 is energized when starting point So,
located between the leading tabular magnet 22A and the following
tabular magnet 22B coincides with the center point Ro of either
the electromagnet 12 or 14. In addition, as illustrated in FIG.
3, in the rotational direction 32 of the tabular magnets 22A
through 22H, the first and the second magnet rotors 6 and 8 are
de-energized when the last tabular magnet 22A has passed. In the
embodiment, an end point Eo is set symmetrical to the starting
point So on the rotating disk-shaped surface 24. When the end
point Eo coincides with the center point Ro of either the
electromagnet 12 or 14, the electromagnet 12 or 14 is
de-energized, respectively. As will be described later, with the
center point Ro of the electromagnet 12 or 14 arbitrarily set
between the starting point So and the end point Eo, the magnet
rotors 6 and 8 start to rotate when the electromagnets 12 and 14
and their tabular magnets 22A through 22H face one another. When
a microswitch is used as the detector 30 for detecting the
rotating position, the contact point of the microswitch is
allowed to slide along the surface of the rotating disk-shaped
surface 24. A step is provided for the starting point So and the
end point Eo so that the contact of the microswitch closes
between the starting point So and the end point Eo. The area
along the periphery therebetween protrudes beyond the other
peripheral areas of the rotating disk-shaped surface 24. It is
apparent that a photo sensor or the like may be used instead of
the microswitch as the detector 30 for detecting the rotating
position.

As shown in FIG. 4, the windings of the electromagnets 12 and
14 are connected to a DC power source 42 through a movable
contact of a relay 40, which is connected in series with the
windings. A series circuit containing the relay 40 (solenoid)
and the detector 30 or microswitch is connected to the DC power
source 42. In addition, from the viewpoint of energy
conservation, a charger 44 such as a solar cell is connected to
the DC power source 42. It is preferable that the DC power
source 42 is constantly chargeable using solar energy or the
like.

In the magnetic rotating apparatus illustrated in FIGS. 1 and
2, a magnetic field distribution shown in FIG. 5 is formed
between the tabular magnets 22A through 22H, disposed on each of
the magnet rotors 6 and 8, and the electromagnets 12 and 14
which face them, respectively. When the electromagnet 12 or 14
is energized, a magnetic field of a tabular magnet of the
tabular magnets 22A through 22H, adjacent to the electromagnet
12 or 14, is distorted in the longitudinal direction in
correspondence with the rotational direction. This results in
the generation of a repulsive force therebetween. As is apparent
from the distortion of the magnetic field, the repulsive force
has a larger component in the longitudinal or perpendicular
direction, and produces a torque, as shown by an arrow 32.
Similarly, a magnetic field of a tabular magnet of the tabular
magnets 22A through 22H, which next enters the magnetic field of
the electromagnet 12 or 14, is distorted. Since it moves toward
an opposite pole of the preceding tabular magnet of the tabular
magnets 22A through 22H, its magnetic field is distorted to a
larger extent, and thereby flattened. This means that the
repulsive force produced between the tabular magnets of the
tabular magnets 22A through 22H, which have already entered the
magnetic field of the electromagnets 12 or 14, is larger than
the repulsive force developed between the next-entering tabular
magnets of the tabular magnets 22A through 22H and the
electromagnets 12 or 14. Accordingly, a turning force, shown by
the arrow 32, acts upon the rotating disk-shaped surface 24. The
rotating disk-shaped surface 24, having been imparted thereto
turning force, continues to rotate due to inertial forces, even
when it has been de-energized after the end point Eo has
coincided with the center point Ro of the electromagnet 12 or
14. The larger the inertial force, the smoother the rotation.

At the initial stage of the rotation, an angular moment, as
that shown in FIG. 6, is imparted to the rotating disk-shaped
surface 24. That is, at the start of the rotation, as shown in
FIG. 6, when the pole M of a tabular magnet is slightly
displaced in the rotational direction from the pole M' of an
electromagnet, a repulsive force operates between both of the
poles M and M' of the tabular magnet at the rotating side and
the electromagnet at the stationary side, respectively.
Therefore, from the relationship illustrated in FIG. 6, an
angular torque T is generated based on the formula: T=F. a.cos
(.alpha.-.beta.), where in a is a constant. The angular torque
starts the rotation of the rotating disk-shaped surface 24.
After the rotating disk-shaped surface 24 has started rotating,
its rotating speed gradually increases due to an inertial moment
thereof, which allows a large turning driving force to be
produced. After a stable rotation of the rotating disk-shaped
surface 24 has been produced, when a necessary electromotive
force can be developed in an electromagnetic coil (not
illustrated) by externally bringing it near a rotated body 10 to
be rotated along with the rotating disk-shaped surface 24. This
electric power can be used for other applications. This rotating
principle is based on the rotating principle of the magnetic
rotating apparatus already disclosed in Japanese Patent
Publication No. 61868/1993 (U.S. Pat. No. 4,751,486) by the
inventor. That is, even if an electromagnet, provided for one of
the rotors of the magnetic rotating apparatus disclosed in the
same Patent Application, is fixed, it is rotated in accordance
with the rotating principle disclosed therein. For details,
refer to the above Japanese Patent Publication No. 61868/1993
(U.S. Pat. No. 4,751,486).

The number of tabular magnets 22A through 22H is not limited to
"8" as shown in FIGS. 1 and 3. Any number of magnets may be
used. In the above-described embodiment, although the tabular
magnets 22A through 22H are disposed along half of the
peripheral area of the disk-shaped surface 24, and the balancers
20A through 20H are disposed along the other half of the
peripheral area, the tabular magnets may further be disposed
along other areas of the disk-shaped surface 24. It is
preferable that balancers, in addition to magnets, are provided
along a portion of the peripheral area on the disk-shaped
surface. The counter weights, which do not need to be formed
into separate blocks, may be formed into one sheet of plate
which extends on the outer peripheral area of the disk-shaped
surface. In addition, in the above-described embodiments, while
the construction is such as to allow the electromagnets to be
energized for a predetermined period of time for every rotation
of the rotating disk-shaped surface, the circuit may be so
constructed as to allow, upon increased number of rotations,
energization of the electromagnets for every rotation of the
rotating disk-shaped surface, starting from its second rotation
onwards. Further, in the above-described embodiment, a tabular
magnet has been used for the permanent magnet, but other types
of permanent magnets may also be used. In effect, any type of
magnet may be used as the permanent magnet means as long as a
plurality of magnetic poles of one type is disposed along the
outer surface of the inner periphery and a plurality of magnetic
poles of the other type are disposed along the inner peripheral
surface of the disk-shaped surface, so that a pair of
corresponding magnetic poles of one and the other polarities is
obliquely arranged, with respect to the radial line 11, as shown
in FIG. 3.

Although the tabular magnets 22A through 22H are mounted on the
magnet rotors 6 and 8 in the above embodiment, they may be
electromagnets. In this case, the electromagnets 12 and 14 may
be the alternative of electromagnets or permanent magnets.

According to the magnetic rotating apparatus of the present
invention, rotational energy can be efficiently obtained from
permanent magnets. This is made possible by minimizing as much
as possible current supplied to the electromagnets, so that only
a required amount of electrical energy is supplied to the
electromagnets.

It should be understood that many modifications and adaptations
of the invention will become apparent to those skilled in the
art and it is intended to encompass such obvious modifications
and changes in the scope of the claims appended hereto.

**KeelyNet: BBS Posting from Henry Curtis (11-18-1997)**


**Korean Magnetic Perpetual Motion Wheel**

I must apologize for not having all the details of this
interesting device but will update the file when I get more info
from the source. In email communications with John Schnurer, I
happened to mention it and he's been on me since then to send
him a diagram, yet I felt like it would simply be confusing
because its operation is not clear or readily apparent from the
information I had.The information that I have comes directly
from long time friend Henry Curtis of Colorado. We both attended
the 1997 ISNE conference in Denver and Henry was telling about
this interesting machine he had seen while on a trip to the
Phillipines. He said there was a free energy conference held
there and he noticed a spinning bicycle wheel that was attached
to a stand that sat on a table.The wheel was running when he
first saw it, yet there did not appear to be any driving force
such as a motor, belts, gears, etc..Henry said he watched it for
quite awhile and it never stopped running. On expressing
curiosity about the wheel, he was invited to stop it and start
it up without any outside assistance.Henry reports the wheel was
brought to a complete stop, then he gave it a spin with his hand
and it began moving on its own. I am uncertain if it followed
the tendency of other such devices to establish its own speed.
Some devices like this can be spun up to high speed from an
outside source, then will slow to a speed which is determined by
the geometry and strength of the repelling or attracting forces
that operate it.Henry swears it was the neatest thing he'd ever
seen and drew a crude diagram of the arrangement on my notepad.
Unfortunately, we were a bit rushed and I did not achieve a
complete understanding of how it operated. That is why I did not
want to blow smoke about it until more detail had been received,
god knows, we don't need any more of that.However, perhaps
someone can figure it out from the limited information I do
have. The following drawing shows the wheel arrangement, one
half was weighted, the other half had slanted magnets. I do not
know whether they are all repelling, attracting or a mix of
these forces.

![](curtis.jpg)

As you can imagine, the weight of the magnets must equal the
weight of the other half of the wheel to balance out. Apparently
the force of the magnetic repulsion or attaction provides the
actual imbalance.Henry also said there was a patent on this
device that is dated January 14, 1997. The inventor is a
Japanese man named Minatu. The spelling of this name is
uncertain. I did a search on the IBM server but found nothing
even remote. Henry specifically said this was a United States
patent. So, here it is. Perhaps Henry can come up with some more
detail which can be used to update this file in future. Good
luck....

**KeelyNet: Update and Corrections from Henry Curtis (Wed, 19
Nov 1997) ~**

*From:* Henry Curtis  ~ *To:* Jerry Decker

*Subject:* Bicycle wheel correction and update Jerry,
Again we see that communication is difficult and memories are
fallable. Obviously I am remiss in not having sent this to you
months ago as I intended to, but as a sage of old observed "The
spirit is willing, but the flesh is slow." During the first
weekend of May, 1997, a group in Soeul, Korea headed up by Mr.
Chi San Park, held The First International New Energy Conference
in Seoul, Korea. I attended this conference and gave a talk on
various approcahes to free energy. It was at this conference in
Seoul, Korea that I saw the bicycle wheel and had the
opportunity to work with it unattended by anyone else.The
inventor is Kohei Minato, a Japanese rock musician, who reports
that he has spent a million dollars out of his own pocket
developing magnetic motors, because the world needs a better
source of energy. He has several patents in various countries.
His latest patent that I am aware of is United States Patent #
5,594,289. His development efforts have gone in the general
direction of the Adams motor which the above patent is similar
to. He had a working prototype of this design at the conference
and reported that it used 150 watts power input and produced 450
watts output on a sustained basis. About a year ago CNN (in the
US) had a 10 minute segment about him and his motors. In this
video he is shown demonstrating two of his magnetic motors. I
have a copy of this film clip that he gave to me. I will make a
copy and send it to you. Unfortunately, the editors were not
attuned to technical details and the pictures of the running
machines show little useful detail. The Phillipine connection
that you mention is completely erroneous. It was in Korea. The
drawing on the web site is essentially correct with the
following exceptions. The counter weight is a single curved
piece of aluminum covering 180 degrees. Each of the several
individual magnets on the other half of the wheel are slightly
asymmetric, crescent shaped and nested. They are magnetised end
to end with the N poles out. The motor is actuated by moving the
N pole of a large permanet magnet (the drive magnet) toward the
wheel. As this magnet is moved toward the wheel, the wheel
starts to spin. As the magnet is moved closer to the wheel it
spins faster. The acceleration of the wheel is rapid. So rapid
in fact, as to be startling. To put it another way I was very
impressed. The motor works. And it works very well. In the film
clip a slight pumping action of Minato's hand holding the magnet
is apparent. When I braced my hand so that there was no pumping
action, the motor still ran. In fact it seemed to run better.
Pumping action by the hand held magnet is not the power that
drives the motor. When the drive magnet is moved away from the
wheel it coasts rather quickly to a stop and comes to rest in a
manner typical of any spinning bicycle wheel. Again when the
wheel is at rest and a large magnet is moved up to the wheel it
starts to spin. At no time is it necessary to touch the wheel to
get it to rotate. Simply bring the N pole of a large magnet
several inches from the wheel. The particular orientation of the
wheel when it is at rest seems to have no effect on how well it
starts to turn. Irrespective of how the wheel and the magnets on
it are sitting; move the drive magnet near, it starts to spin.
Move the magnet closer it spins faster. Move the magnet further
away it slows up. The wheel was mounted on a stand made of
aluminum angle pieces bolted together similar to the diagram in
the above mentioned patent. The axle of the wheel was mounted
parellel to the surface of the planet. I have attached a rough
diagram of the wheel. Apparently the geometry of the magnets on
the wheel is very important and subtle. I have built several
small models none of which have shown the free energy effects of
Minato's machine. The conference in Seoul was attended by
several hundred people, most appeared to be under 40 and evenly
divided between men and women. Presenters were from Korea, US,
Japan, and China. Simultaneous translation was provided for all
talks in the 3 day conference. Jerry, I hope this information is
useful. I may be contacted by e-mail at

**KeelyNet: Email from Gene Mallove at *Infinite Energy ~***

I spoke to Bob Vermillion of Tri-Cosmos Development (Los
Angeles, CA 310-284-3250 or fax 310-284-3260) today, just before
he left for the three-day demonstrations of the Minato magnetic
motor being held in Mexico City, Mexico on July 8, 9, 10th.Three
(3) Minato Motors (MM), covered by US Patents # 5,594,289 (Jan
14, 1997) and # 4,751,486 (June 14, 1988), have been brought
over from Japan. One was allegedly tested last evening by Grupo
Bufete Industrial (supposedly one of the largest power
generation construction companies in Mexico and South America).
The company engineers were said (by Vermillion) to have measured
an output /input ratio of 4.3 / 1. The printed literature, which
I received in a Fedex packet from Vermillion states that the
device can put out 500 watts (maximum) with an input of 34
watts.For those of you who wonder why the device is not
self-sustaining -- oral info from Vermillion is that Minato
\*will\* in the course of one of the demonstrations \*remove the
battery power supply\* and let the device self-run -- presumably
with a load. The press release makes no bones about the
physics-busting character of the MM: "As rotations per minute
(rpm's) increase, the electromagnetic consumption of the stator
decreases. This phenomenon is in direct conflict with accepted
laws of physics and is achieved through the repelling magnetic
fields. It operates without heat, noise, or pollution of any
kind. It can be produced in size from ultra-small to very
large." It is said in the press release that applications from
cell phones to laptop computers are under development.
Vermillion told me of other parties who were planning to attend
the demonstrations, which will be conducted both in public
displays and with private party measurements. These include:
ENRON, Bechtel, Tejas (a division of Shell Oil Corporation),
Fluor Daniels, Kellogg Corp. .He told me that Hal Fox of New
Energy News and the Fusion Information Center will be there (I
confirmed with Hal that he will be there and will give us a full
report.) I considered going myself (I was invited), but I trust
Hal Fox to provide a full report -- he should be back this
weekend. Mr. Kohei Minato will be there -- he has already
arrived, I understand. He hand carried one of the motors that
was already tested yesterday. The wealthy Japanese individual
who owns Tri-Cosmos Dev. Co. is Mr. Charly Fujiki. Attendance is
by invitation only, but let me here provide the Grupo Bufete
numbers: (723-45-78 and Fax 723-47-18 in Mexico City). The
exhibition will be in the Grupo Bufete Industrial building.The
invitation says: "Mr. Minato, the inventor, will be present to
explain and demonstrate his remarkable breakthrough in
technology to government and business leaders in Mexico. He will
also discuss the possible use (and) application for various
other industries, including a giant generator project, based on
the principal mechanism being displayed."Daily demonstrations
are from 10:30 am to Noon, 4:30 to 5:30 pm and 6 to 7:30 pm. A
block diagram of the motor indicates that it is about 500 kg. An
arrow indicates that its 500 watt output goes to a load --
schematically indicated as an array of light bulbs. The unit is
within a cube 1.2 meters on edge.The diagram shows a solar
panel(!!) providing input to the battery that powers the device
- I supposes for completeness, but that is obviously silly in
view of the claim. Vermillion assured me that this solar panel
was not an essential part of the system. One of the two color
brochures in the package shows the Minato motor with its
charactersitic coils that have their pole faces toward the
perimeters of permanent magnet containing wheels that are
stacked on an axle. If you look at the thing quickly, you'd
think you were looking at a steam turbine. The 1997 patent
#5,594,289 states in its abstract: "On a rotor which is fixed to
a rotatable rotating shaft, a plurality of permanent magnets are
disposed along the direction of rotation such that the same
magnetic pole type therof face outward. In the same way,
balancers are disposed on the rotor for balancing rotation of
this rotor. Each of the permanent magnets is obliquely arranged
with respect to the radial direction line of the rotor. At the
outer periphery of the rotor, an electromagnet is disposed
facing this rotor, with this electromagnet intermittently
energized based on the rotation of the rotor.According to the
magnetic rotating apparatus of the present invention, rotational
energy can be efficiently obtained from permanent magnets. This
is made possible by minimizing as much as possible current
supplied to the electromagnets, so that only a required amount
of electrical energy is supplied to the electromagnets." It will
be interesting, indeed, to learn what comes out of this.Perhaps
the famous white rabbit disappearing down a hole, or maybe the
birth of a revolution? We shall see.

**KeelyNet: Response from STAG group on Minato Wheel
(12-04-97) ~**

To: Jerry  ~ From: David Heard

Subject: Re: Howdy! Thanks for your mail regarding Minato's
Rotation Aparatus. My apologies for the slight delay in
replying. Yes, please feel free to put up a link to our site and
the photos. I should explain that our group is not in any way
conected with Mr. Minato himself. The group STAG is run by
foreign scientists who are living in Japan with the aim of
distrubuting information between themselves, improving links
between Japan and the UK (and elsewhere) and of course to have
the odd beer or two. We hold meetings every couple of months and
invite speakers to speak on interesting or topical subjects. Mr.
Minato was one of the speakers who gave a presentation at one of
our meetings. Hence the pictures. I also heard about the Korean
conference, and saw a significant report written about it in the
conference proceedings (albeit in Korean!). I think it would be
really good if other people did produce similar devices. I will
pass your comments on to Mr. Minato. He did have a Web page, (in
Japanese) with information on it, but I haven't been able to
connect to it recently. Thanks again for your mail. Regards,   
David Heard, Vice Chairman, STAG

so I will put up a link to your photos.... Do you think there
will be full details on how to build the simple self-running
bicycle version posted so that others can duplicate it....this
would really set it off if these things were being shown all
over the world.... I got copies of the three patents (two by
Minato, one by Gavaletz) and have their locations posted on my

bigtime until at least a simplified version that self-runs has
beend duplicated by many others....this will set the fire that
will draw attention to the rest.....good luck, I and a lot of

**"Minato is going Big-Time!"**

*Subject:* Minato's PPM Update Vortexians: Here is an
update on Kohei Minato's over-unity permanent magnet inventions.
Minato is currently having manufactured, over in Japan, a large
unit, (4) connected 10 foot long units, that can power 30 homes.
It is estimated to be finished by February. CNN is scheduled to
report on it when ready. Minato also has a home powering unit.
Both size units are based on his USA Patent 5,594,289 that uses
a battery to start and stop the unit. The USA sales
representative is Bob Vermillion and his e-mail address is:
polenetic@aol.com

No web site yet but Bob Vermillion's office is in Century City,
California and he said he can answer your technical, marketing,
and manufacturing questions. He just came back from visiting
Minato's lab in Japan and was impressed seeing the units working
versus seeing the photo's. A power demonstration unit to is
expected to arrive from Japan in January. There currently is no
USA manufacturing being done and licenses are available
worldwide. I mentioned to Bob that there is also a large
interest for a permanent magnet rotor/stator unit that is
self-rotating and self-starting, like Minato's bicycle wheel
design. I also mentioned that a table top version of this, for
the student or as an "executive toy," would sell quite well. He
didn't know this. If any of you do e-mail to Bob for info,
mention to him about the need for a table top version of the
bicycle wheel and where you got his address!

**"Minato Demo and Update"**

Here is an 3/4/98 update on Kohei Minato's over-unity permanent
magnet inventions from his USA sales representative's Bob
Vermillion and John Kenworthy. Mr. Minato demonstrated at the
Japanese "Energy Expo '98" his large unit, (4) connected 10 foot
long units that can power 30 homes, and several smaller table
top units. CNN, NHK and other TV networks took video's of his
devices, and of the whole Expo, but he did not know when it was
re-broadcasted. Minato's staff had their own video on for the
four day event and Bob is making copies of a typical single day
video coverage. There were not any instruments connected to the
large unit to measure energy input to output but his table top
unit was connected and it showed 48 Watts input to 550 Watts
output. Minato's demonstration attracted a lot of public
attention by the large daily crowds and also from a number of
interested Japanese corporations. Bob said he received all of
your e-mail's and took them back with him to Japan and gave a
copy to Mr. Minato and his staff to show the interest here in
the USA and the world. He has not replied to all of your
e-mail's due to there is nothing to report about just yet and he
will answer all of your e-mail's when he has at least a
demonstration unit to show. They are still waiting for a table
top power demonstration unit for their Los Angeles office but
the Japanese engineer's want to perfect it first. Bob is looking
forward to receiving a magnetic "bicycle wheel" unit in April
and interested parties can then schedule an appointment to see
the wheel spinning by itself without any energy input! :-)

**New Energy News 6(3): 1 (July 1998): Press Release**   
**Institute for New Energy (INE)**

**"The Magnetic Rotating Apparatus"**

[If the following Press Release is reporting factual
information that can be verified, then this may be the first
commercial over-unity rotating, magnetic new-energy device. The
first western hemisphere demonstration will be given in Mexico
City in early July, 1998.

Inventor Kohei Minato, the Thomas Edison of the new millennium,
has acquired more than 50 patents and intellectual property
rights from all over the world for the energy creating "Magnetic
Rotating Apparatus." Mr. Minato's generating device utilizes the
magnetic force of repulsion to create and emerge clean safe
energy.

The "Magnetic Rotating Apparatus" employs a number of
stationary neodymium magnets arranged at regular intervals on
the peripheral portion of a rotor. The polarity of each magnet,
which is located radially outward from the rotor, is identical.
The machine is started with an electromagnetic stator. When
activated, the magnetic fields repel creating rotation of the
rotor. As the rotations per minute (rpm's) increase, the
electrical consumption to the electromagnetic stator decreases.
This phenomenon is in direct conflict with accepted laws of
physics and is achieved through the repelling magnetic fields.
It operates without heat, noise or pollution of any kind. It can
be produced in size from ultra small to very large.

One of the prototypes available for viewing operates with an
input of 34 watts of electricity and outputs a maximum of 500
watts. "Magnetic Rotating Apparatus" applications currently
under development include usage from cell phones and laptop
computers to automobiles and giant power stations.
