Reducing harmonic losses in dynamoelectric machine rotors.

摘要

A solid rotor (22) for a dynamoelectric machine including field conductors (44,46) in axial slots (16,18) and axial ventilation passages (102) is provided with low resistivity thermally conductive axial winged inserts (48) 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. <IMAGE>
