ABSTRACT:
A method of making a rotor for a dynamoelectric machine comprises the steps of forming a plurality of flux ring segments of flux conducting material. Segments of magnetizable material are then secured to each of the flux ring segments to form a ring-segment magnetizable material subassembly. A plurality of subassemblies are situated in a cylindrically shaped molding ring, with the magnetizable material adjacent to the inside walls of the molding ring. A shaft is situated in the molding ring along the axis of the cylindrical molding ring. A plastic material is molded around the shaft and inside the ring-segment-magnetizable material subassemblies whereby the outermost surfaces of the magnet material define a cylinder.
