Abstract
A method for winding a stator that may be used for single-phase and three-phase motors. The stator windings are spread across several slots of the stator so that some of the slots receive winding portions of several phase windings. The windings are made by using a mandrel that has step-formed portions with a plurality of winding surfaces. Some of the winding surfaces lie in the same plane so as to permit the windings wound thereon to fit properly into the slots of the stator.
