Patent ID: 8258665

Claim:
An AC electrical rotating machine having a high number of phases, a low base pole count, and the ability to react to a variety of different harmonic drives comprising: a. a substantially cylindrically shaped stator with a cylinder top surface, a cylinder bottom surface, a smooth outer surface, and an inner surface including a plurality of slots spaced circumferentially along said inner surface; b. a plurality of conductive coils wound toroidally along said stator inner surface, across said cylinder bottom surface, along said stator outer surface, and across said cylinder top surface so that each coil of said plurality of coils forms a loop positioned in each of said plurality of stator slots to substantially completely fill said slots, thereby forming an outside-wound stator wherein each coil has two terminals and producing a high number of phases and a low base pole count; c. a cylindrical rotor with a substantially smooth facing surface mounted for rotation relative to said stator internally of said stator inner surface and concentric with said stator to form a uniform gap between said rotor facing surface and said stator inner surface; and d. drive means for supplying a source of alternating current to provide more than three drive phases to said plurality of coils, wherein said drive means is configured to operate with variable harmonic drive to produce an impedance effect.
