Patent ID: 7309938

Claim:
A rotary power converter apparatus for coupling power between a prime driver and plural generators, comprising: a frame having a first and second bearing aligned along an axis of rotation; a rotor assembly, further comprising: a shaft fabricated from a light weight material, and rotatably supported along said axis of rotation by said first and second bearings; a prime-driver rotor assembly, having a magnetic structure supported by a light weight non-magnetic alloy hub fixed to rotate with said shaft; plural generator rotor assemblies, each having a permanent magnet structure supported by a light weight non magnetic alloy hub fixed to rotate with said shaft; a prime driver stator assembly fixedly supported by said frame and aligned concentric with said prime driver rotor assembly to enable magnetic coupling of power therewith; plural generator stator assemblies fixedly supported by said frame, and each aligned concentric with one of said plural generator rotor assemblies to enable magnetic coupling of power therewith, and wherein said prime-driver rotor assembly and said prime driver stator assembly are configured as a multi-pole brushless DC motor, and a pulse width modulated DC servo drive coupled to energize said multi-pole brushless DC motor.
