Abstract

A generator rotor includes a rotor body having defined pole regions with pole faces and parallel sides adjacent the pole faces. A winding module is fitted over the parallel sides of the rotor body, and a pair of spindles are secured to respective ends of the rotor body. The spindles secure opposite sides of the winding module to the rotor body. The spindles preferably include a notch that is shaped to receive one side, respectively, of the winding module. With this construction, flat windings can be used for the winding module, eliminating the need for a curved module to fit over the spindle.
