    "title": "Elliptical Armature Alternator / Generator / Motor - Dynaflux design reduces Lenz Law resistance for ultra-high efficiency",
    "inventor_name": "Jim Murray III",
    "publication_year": null,
    "device_name": "Dynaflux Alternator",
    "goal": "Achieve ultra-high electrical conversion efficiency by reducing Lenz-law back-torque resistance in generators/motors.",
    "problem_addressed": "Conventional generators suffer from Lenz-law induced back torque (back EMF) that limits efficiency.",
    "concept_summary": "The Dynaflux machine uses an oblique/elliptical rotor armature so that magnetic flux moves parallel to the rotation axis rather than perpendicular. This geometry redirects the Lenz reaction into axial thrust instead of opposing torque, thereby reducing back-EMF and enabling much higher conversion efficiencies.",
    "detailed_description": "Patented in 1988 (US 4,780,632), the device features a rotor whose windings are mounted obliquely with respect to the axis of rotation. As the rotor turns, the magnetic flux reciprocates along the axis, producing two AC cycles per rotation. The design maintains a constant air gap and may incorporate multi-pole stators, toroidal windings, and back-EMF reduction techniques. Variants include multi-pole switched reluctance DC motors and toroidal motors with constant torque characteristics.",
