ABSTRACT:
A rotor construction and end turn supporting arrangement for restraining field winding end turns within circumferential slots formed in dynamoelectric machine rotors. Longitudinal slots axially disposed along the rotor intersect the circumferential slots and provide an open-faced housing for disposal therein of the field winding between the axially separated circumferential slots. Wedges are provided for insertion in at least some of the slots for retention therein of the field winding during high-speed rotor rotation. Utilizing electrically conductive wedges in both the longitudinal slots and circumferential slots establishes a rotor cage for carrying undesired eddy currents which are often induced in the rotor material.
