  • Patent number: 11658522
    Abstract: An electric machine includes a stator and a rotor. The stator has a yoke fitted over a ring that has a plurality of teeth with gaps therebetween for fitting metal windings. The ring of teeth has an inner circumference that is closed and to connect the teeth, and an outer circumference with open gaps or slots between the teeth. The metal windings are fitted through the open outer circumference. Regions of the closed inner circumference between the teeth are treated such that the region's magnetic permeability is reduced relative to the remainder of the stator. The reduction in magnetic permeability provides a magnetic flux barrier between the teeth.
