Electric machine with multiple toothed spacers in coils

Abstract

An electric machine includes a plurality of coils, at least one first yoke, at least one second yoke, and at least one intermediate yoke between the at least one first yoke and the at least one second yoke. Each coil defines a coil opening that includes a first section, a second section, and an intermediate section between the first section and the second section. A plurality of first wedge-shaped teeth is integrally formed with and extends from the at least one first yoke into a differing one of the plurality of coil openings in the first section thereof. A plurality of second wedge-shaped teeth is integrally formed with and extends from the at least one second yoke into a differing one of the plurality of coil openings in the second section thereof. A plurality of intermediate wedge-shaped teeth is integrally formed with and extends from the at least one intermediate yoke into a differing one of the plurality of coil openings in the intermediate section thereof.
