Geometry for single-layer wound stators with high manufacturability

Abstract

An electric motor comprises a stator and a rotor having a specified number of rotor poles that magnetically interact with the stator so as to rotate in relation to the stator. The stator is a slotted stator with a specified number of stator poles with slots between those poles and is provided with a set of conductive windings that are fitted into the slots and wound around the stator poles according to a specified pattern. The motor has a single-layer winding configuration, wherein there are one or more empty stator poles without windings on each side adjacent to those stator poles with a winding, so that only one set of windings is present in each slot. Stator poles with a winding terminate in a stator shoe, while stator shoes are absent from each empty stator pole, thereby expanding the gap for machine winding into the slots.
