A rotary power converter apparatus for coupling power between a prime
driver and plural generators. The apparatus includes a frame having a
first and second bearing aligned along an axis of rotation and a rotor
assembly supported thereby. The rotor assembly includes a shaft
fabricated from a light weight material that is rotatably supported along
the axis of rotation by the first and second bearings. There is a
prime-driver rotor assembly, that has a magnetic structure supported by a
light weight non-magnetic alloy hub that is fixed to rotate with the
shaft. There are also plural generator rotor assemblies, each having a
permanent magnet structure supported by a light weight non magnetic alloy
hub also fixed to rotate with the shaft. A prime driver stator assembly
is fixedly supported by the frame and aligned concentric with the prime
driver rotor assembly to enable magnetic coupling of power therewith.
There are also plural generator stator assemblies fixedly supported by
the frame, and each aligned concentric with one of the plural generator
rotor assemblies to enable magnetic coupling of power therewith.
