A method may include providing a stator. The method may also include equipping the stator with quadruple three-phase winding sets with concentrated fully-pitched winding. The quadruple three-phase winding sets may be connected in such a way that emulates a six-phase stator. Further, the quadruple three-phase winding sets may have the same conductor cross-sectional area. In addition, the quadruple three-phase winding sets may include a plurality of winding groups.
