Abstract
An improved rotor for a dynamoelectric machine which includes a rotor core of magnetizable material having a longitudinal axis and axially spaced core ends, winding end supports of electrically insulating material at the core ends, and a winding having a plurality of layers of continuously connected turns of wire and first and second exciter lead portions at electrically opposite ends of the winding. The first exciter lead portion includes a crossover section oriented generally transverse to the longitudinal axis and located at one of the core ends. The winding is oriented generally parallel to the longitudinal axis and extends around the core, over the crossover section of the first exciter lead portion of the winding, and over both winding end supports, forming a plurality of end turns at the core ends and thereby maintaining the core and the winding end supports fixed relative to each other and constraining the crossover section of the first exciter lead portion between the end turns and the winding end support. A slot and a recessed area are incorporated into the winding end support, with the slot allowing the crossover section of the first exciter lead portion of the winding to be conveniently routed between the end turns and the winding end support, and the recessed area providing constraint for the end turns, thereby preventing deformation of the end turns due to centrifugal forces incident with rotation of the rotor.
