Abstract
A gear-reduction planetary rotor assembly for an electric machine having a housing containing a stator and a stationary reaction shaft, the gear-reduction planetary rotor assembly includes an output shaft disposed along a drive axis. The gear-reduction planetary rotor assembly further includes a carrier having one or more magnets and disposed within the housing for rotation about the drive axis by interaction of the magnets with an electric field produced by the stator. The gear-reduction planetary rotor assembly further includes a planet gear carried by the carrier to interact with the stationary reaction shaft and revolve about the drive axis. The gear-reduction planetary rotor assembly further includes a sun gear coupled to or integral with the output shaft and meshing with the planet gear to rotate the output shaft about the drive axis.
