ABSTRACT:
A high speed generator has its main rotor located within the main generator shaft assembly. The main rotor is mounted on a substantially hollow rotor shaft, which is also mounted within the main generator shaft assembly. The main stator surrounds at least a portion of the main generator shaft assembly. Main rotor cooling supply orifices extend through the rotor shaft. Main stator cooling supply orifices, which are in fluid communication with the main rotor cooling supply orifices, extend through the main generator shaft assembly. Cooling fluid is directed into the main generator shaft assembly, and flows through the main rotor cooling supply orifices and the main stator cooling supply orifices. The main rotor and main stator cooling supply orifices are configured to supply the main rotor and main stator with a cooling fluid spray. This configuration reduces the rotational fluid mass associated with flood-cooled rotors, which increases structural integrity, lowers material stresses, improves rotor dynamics.
