Abstract
A first winding portion from a set of winding portions has a set of coils. Each coil of the first winding portion is associated with a different electrical phase from a set of electrical phases. Each coil of the first winding portion circumscribes a different area from a set of areas circumscribed by the set of coils of the first winding portion. A second winding portion has a set of coils associated with the set of electrical phases and a third winding portion has a set of coils associated with the set of electrical phases. The first winding portion at least partially overlaps the second winding portion and the third winding portion such that each area from the set of area is substantially circumscribed by a coil associated with each electrical phase from the set of electrical phases.
