Abstract: 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.

Abstract: 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.

Abstract: A work vehicle drive includes a housing; an electric machine at least partially housed within the housing, configured to generate rotational power, and comprising an interface coupling at an electric machine output; a transmission at least partially housed within the housing, rotationally coupled to the interface coupling, and configured to transfer at least a portion of the mechanical power from the electric machine to a drive output; a pump at least partially housed within the housing and configured to facilitate circulation of lubrication fluid about the transmission, wherein the pump is selectively driven, in a first mode of operation, by the rotational power of the electric machine; and a solenoid device at least partially housed within the housing and configured to selectively drive the pump in a second mode of operation.

Abstract: A final drive assembly is provided for powering a ground-engaging mechanism of a work machine. The final drive assembly includes a plurality of power-transferring devices each having an output and a planetary gearset assembly including a plurality of planetary inputs and a planetary output. The planetary output is configured to transfer power from the plurality of planetary inputs to the ground-engaging mechanism. Each of the plurality of planetary inputs is coupled to one output of the plurality of power-transferring devices.
