Abstract
Rotor windings for a thermo pump-cooled generator have an internally formed cooling passage having a cooling inlet on a radial underside of the motor end winding portion and a cooling outlet on a radial upper side of the axial portion that is oriented within the generator air gap. The cooling passage in the rotor winding exhausts air from end winding portions that are circumscribed by a generator retaining ring into the generator air gap.
