Abstract
An electrical machine includes a stator having a radically inwardly directed duct adjacent the center of the machine for flowing cooling medium into the gap between the stator and rotor. The rotor includes radial or diagonal ducts having scoops for directing flow generally radically inwardly to cool the field windings in the center of the machine. The cooling medium flows either into subslots for radial or diagonal outward flow through outlet ducts for return to the gap.
