ABSTRACT:
An improved rotor assembly for a dynamoelectric machine having poles which are provided with slots that form channels to receive a retaining cover or wedge to retain field windings located in a recess between adjacent poles. The slots cooperate with lips on each end of the retaining wedge to prevent the wedge from deforming and separating from the rotor as a result of centrifugal forces developed during high speed rotation.
