ABSTRACT:
A radial duct for a dynamoelectric machine having a rotor, and a plurality of radial slots in the rotor is provided. A plurality of coils are respectively seated in the radial slots, and the coils form a plurality of radially stacked turns. The radial duct includes one or more cooling slots defined in at least a portion of the radially stacked turns, and extend in a substantially radial direction to the rotor. At least a portion of an interior surface of one or more cooling slots includes one or more ribs for enhanced heat transfer.
