A method of making a first stator winding and a second stator winding comprises a step of forming an open winding arrangement on a first stator core, wherein the open winding arrangement including conductor segments positioned in stator slots with at least four layers of conductor segments in each slot, the open winding arrangement further comprising a plurality of leads to a plurality of the conductor segments. The method further comprises a step of forming the open winding arrangement on a second stator core. In addition, the method comprises a step of closing the open winding arrangement on the first stator core by connecting the leads with first additional conductors to form a three phase winding in a single-shape configuration. Furthermore, the method comprises a step of closing the open winding arrangement on the second stator core by connecting the leads with second additional conductors to form a three phase winding in a multi-shape configuration.
