The stator may have an annular stator ring and a plurality of core tooth-portions extending in a radial direction. The annular stator ring and the plurality of core tooth-portions may be integrally formed of a Soft Magnetic Composite (SMC). The SMC may include one or more isotropic ferromagnetic materials, a magnetic saturation induction of greater than or equal to about 1.6 Tesla, and an electrical resistivity greater than 10 micro-ohm/m.

Abstract: A method of assembling a coil on an irregular-shaped multi-part tooth of an electric machine may include inserting at least one wedge-portion of the multi-part tooth into an opening of the coil such that a broader end of the at least one wedge-portion extends out of the opening in the coil. The method may also include mounting the coil with the inserted at least one wedge-portion on a core tooth-portion of the multi-part tooth such that the broader end of the at least one wedge-portion remains extended out of the opening in the coil, exerting a force on the broader end of the at least one wedge-portion to tighten the coil on the multi-part tooth.

Abstract: A radial flux electric machine includes an inner stator and an outer rotor configured to rotate about the stator. The outer rotor may include a rotor base and a plurality of annularly arranged permanent magnets axially extending from the rotor base parallel to an axis of rotation of the rotor. A cylindrical core may extend from the rotor base encircling the plurality of permanent magnets. The core may be formed of a Soft Magnetic Composite (SMC). A sleeve may encircle the rotor. The sleeve may support the cylindrical core and the cylindrical core may support the plurality of permanent magnets. The cylindrical core may be positioned radially between the sleeve and the plurality of permanent magnets.

Abstract: An electric machine includes a plurality of coils and a plurality of U-shaped clips. Each coil defines a coil opening and each U-shaped clip includes a first tooth, a second tooth, and a yoke interconnecting the first tooth and the second tooth. The first tooth of each U-shaped clip is disposed in one coil opening and the second tooth of each U-shaped clip is disposed in another coil opening of an adjacent coil with the yoke bridging the two adjacent coils. And two sidewalls of the two adjacent coils are sandwiched between the first tooth and the second tooth of each U-shaped clip.

Abstract: An electric machine includes a plurality of electromagnetic coils arranged circumferentially about the axis of rotation. Each coil defines a trapezoidally-shaped and tapered coil opening. The electric machine also includes a plurality of yokes that extend in an axial direction and a plurality of teeth. At least one of the plurality of yokes is tapered in the axial direction, and at least one tooth extends from each of the plurality of yokes. The plurality of teeth are each tapered in a radial direction to enable the plurality of teeth to fit within a corresponding trapezoidally-shaped and tapered coil opening.
