Abstract
A high speed, high power generator has its main stator and main rotor configured to provide enhanced cooling capability. The generator includes a generator housing, a stator, a shaft, and a rotor. The stator is mounted within the generator housing. The shaft is rotationally mounted within the generator housing, and includes an inner surface that defines an internal fluid flow passage, an outer surface, and a plurality of interlamination cooling supply orifices extending between the shaft inner and outer surfaces. The rotor is mounted on the shaft and includes a plurality of poles formed from laminations, and one or more interlamination disks. Each interlamination disk is disposed between at least two of the laminations and includes a plurality of interlamination flow passages that receive a cooling medium from the shaft and direct the cooling medium, via centrifugal force, through the rotor and onto the stator.
