ABSTRACT:
End windings of the field windings of a generator rotor body are flattened. A cap having a flat undersurface overlies the flattened end windings and an enclosure ring extends about the end windings and cap. Apertures are formed through the cap in communication with gaps between the coils of the end windings and passageways formed along the outer surface of the cap. The passageways and apertures form ventilation paths for a cooling medium flowing through the end windings outwardly into the air gap between the rotor body and stator.
