Abstract: A generator cooling assembly is provided and includes a rotor, a generator assembly and an air-cycle machine (ACM). The generator assembly includes a generator housing, a generator housed in the generator housing and a shaft coupled to the rotor to transmit shaft power from the rotor to the generator to drive the generator. The ACM is housed in the generator housing and is receptive of air. The air is cooled by the ACM and output from the ACM to the generator as fully cooled air to cool the generator.

Abstract: A rotor assembly of a generator includes a rotor core including a plurality of core poles defining a plurality of core slots therebetween. The core poles extend from a first axial end of the rotor core to a second axial end of the rotor core. A rotor winding is installed to the rotor core and has a plurality of core segments located in the plurality of core slots, and a plurality of end turns connecting the plurality of core segments. An end plate is located at at least one of the first axial end or the second axial end and includes a plate portion and a plurality of wedge ends extending from the plate portion. Each wedge end is located at a corresponding core slot. The end plate is supportive of the plurality of end turns of the rotor winding.
