Claims19
A rotary motor/generator comprising:
- a toroidal magnetic cylinder radially arranged about an axial axis to form a circular path comprising of at least a first magnetic tunnel segment, wherein the first magnetic tunnel segment comprises:
- a first magnetic wall having a magnetic pole orientation that points generally towards an interior of the first magnetic tunnel segment;
- a first opposing magnetic wall having a magnetic pole orientation that points generally towards the interior of the first magnetic tunnel segment and positioned a predetermined distance from the first magnetic wall;
- a first inner magnetic wall generally spanning between the first magnetic wall and the first opposing magnetic wall and having a magnetic pole orientation that points generally towards the interior of the first magnetic tunnel segment;
- a first outer magnetic wall generally spanning between the first magnetic wall and the first opposing magnetic wall, positioned radially away from the first inner magnetic wall, and having a magnetic pole orientation that points generally towards the interior of the first magnetic tunnel segment;
- wherein like magnetic poles of magnets forming the first magnetic wall and magnets forming the first opposing magnetic wall are of an opposite magnetic polarity orientation than the like poles of magnets forming the first inner magnetic wall and magnets forming the first outer magnetic wall such that the first magnetic tunnel has a NSNS magnetic pole configuration;
- and
- a coil assembly positioned within the circular path.
