Goal
Increase generator efficiency by reducing the counter-torque (back torque) generated by induced currents.
Problem
Standard generators suffer efficiency loss due to back torque produced by the interaction of induced current magnetic fields with the external magnetic field.
Concept Summary
A rotating AC generator with a hollow stator core, a cylindrical rotor, two sets of magnets (north-facing and south-facing) mounted on the rotor, and silicon-steel pieces positioned adjacent to each magnet. The stator contains longitudinally laminated high-permeability steel sheets with slots for a conductor winding. The arrangement is intended to reduce the reaction (back torque) on the rotor, improving overall efficiency.
Principles
- Electromagnetic induction
- Lenz's law
- Fleming's right-hand rule
- Fleming's left-hand rule
