ABSTRACT:
A rotary electric machine such as a brushless generator including a housing, a stator within the housing and a rotor journalled within the housing. A stationary element is affixed to the housing and extends axially into a cavity in the rotor and a barrier is provided in the air gap between the stator and the rotor. The barrier serves to isolate the flow of coolant to the stator from the air gap and the stationary element serves as a means for mounting, within the rotor, components of a permanent magnet generator and an exciter which may be wholly contained within the rotor. The stationary element is also provided with a conduit for conducting coolant to the various components of the rotor.
