Patent ID: 7348703

Claim:
A rotating electromagnetic generator apparatus comprising: a pair of stators each providing a permanent magnet producing a magnetic field within a space between the stators; a ferromagnetic toroidal rotor rotationally mounted within the magnetic field; a plurality of windings wound radially on the rotor, the windings each comprising a plurality of coils and the coils each comprising at least one wrap, the coils interconnected through a switching network mounted on the rotor, the switching network configured for placing each of the coils within each winding alternatively in one of: a) electrical series connection; b) electrical parallel connection; and c) electrically isolated, wherein, within each of the windings, at least two of the coils are in electrical series connection, and, at the same time, at least two of the coils are in electrical parallel connection, whereby a selectable output voltage and output current are produced by rotor rotation.
