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: 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.

Abstract: A method of fabricating a coil for mounting on a tooth of a stator or a rotor of an electric machine includes winding a wire about a mandrel to form a coil having a first shape corresponding to the shape of the mandrel. The method may also include removing the coil having the first shape from the mandrel, and applying a mechanical force on the coil to change the shape of the coil from the first shape to a second shape. The second shape may correspond to the shape of the tooth. The method may also include mounting the coil of the second shape on the tooth.

Abstract: A radial flux electric machine includes a rotor configured to rotate about an axis of rotation, a plurality of electromagnetic coils, and a stator. The stator may include an annular stator ring extending about the axis of rotation and a plurality of multi-part teeth circumferentially arranged on the stator ring. Each multi-part tooth of the plurality of multi-part teeth may include a core tooth-portion integrally formed with the stator ring and at least one additional tooth-portion separate from the stator ring. Each coil of the plurality of electromagnetic coils may be mounted on a different multi-part tooth of the plurality of multi-part teeth such that each coil surrounds a corresponding core tooth-portion of the multi-part tooth with a gap between the coil and the core tooth-portion. The at least one additional tooth-portion may be disposed in the gap.
