Abstract
A high speed generator cooling system directs a cooling oil spray through a chamber inside a coil support wedge assembly, which may be disposed adjacent to the generator coils. Heat from the generator coils may be conducted through the walls of the coil support wedge assembly and into the chamber where it is removed by the cooling oil spray passing through the chamber. The cooling oil passes through a generator rotor shaft and into a cooling passage in least one of the rotor laminations.
