摘要： A high speed, high power generator has its main stator configured with one or more reduced-diameter sections. The generator includes a generator housing, a main rotor, and a main stator. The generator housing has a main stator cooling flow passage formed therein that is configured to receive a flow of a cooling medium. The main rotor is rotationally mounted in the generator housing. The main stator is mounted within the generator housing and surrounds at least a portion of the main rotor. The main stator includes a stator core coupled to the generator housing adjacent the main stator cooling flow passage, and includes two or more nominal-diameter sections and one or more reduced-diameter sections. The nominal-diameter sections each have a first outer diameter, and the reduced-diameter sections, each have a second outer diameter that is less than the first diameter. Each reduced-diameter section is disposed between two nominal-diameter sections and is in fluid communication with the stator cooling flow passage.

摘要： 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.
