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.

Rotor for electric machine

An electric motor includes a stator core and a plurality of stator windings disposed on or in the stator core, with the plurality of stator windings including a plurality of winding end-turns that extend out from the stator core. The electric motor also includes an electrically insulating potting material applied over the plurality of winding end-turns. A cooling passage is formed that defines a cooling circuit through which a cooling fluid is circulated to provide cooling to the plurality of winding end-turns, the cooling passage formed upon dissolving of a chemically soluble material embedded within the potting material.

A complex planetary assembly includes an input, an output, a ring gear, a first stage planetary assembly and a second stage planetary assembly. The first stage planetary assembly includes a first sun gear, a first carrier including a first plurality of pins extending therefrom, and a first plurality of planet gears. Each of the first plurality of planet gears is rotatably coupled to one of the first plurality of pins. The second stage planetary assembly includes a second sun gear, a second carrier including a second plurality of pins extending therefrom, and a second plurality of planet gears. Each of the second plurality of planet gears is rotatably coupled to one of the second plurality of pins. At each of the first or second plurality of pins on the first or second carrier, at least two planet gears of the first or second plurality of planet gears are coupled and coaxially arranged adjacent to one another.
