Abstract
A solid rotor for a dynamoelectric machine including field conductors and ventilation passages in axial slots is provided with low resistivity thermally conductive axial winged inserts which seal and overlie the slots to form a low resistivity cylinder about the rotor to minimize power losses and associated heating due to harmonic induced eddy currents, enhance the conductive cooling of the rotor, and increase efficiency.
