Abstract
A rotor for a dynamoelectric machine comprises a discoidal winding of conductors bonded together by means of a resinous material. The structure has a flat disc portion containing the coil sides and outer and inner ring portions containing the coil end-heads and other end connections. Surfaces on the discoidal structure have formations which interrupt areas exposed to the cooling fluid in the machine. This enhances heat transfer from the winding conductors to the fluid.
