摘要： A set of interchangeably pairable end caps is provided for electrically insulating a variety of stator cores having differing axial stack heights. Each pair of end caps cooperatively defines a generally radially projecting, generally axially extending wire barrier including axially opposed ends. Each of the ends forms a respective rounded winding ramp configured to smoothly guide wiring into a wire trough in part defined by the wire barrier.

摘要： A rotor is provided for use in an electric motor. The rotor is rotatable about an axis. The rotor includes a core including a plurality of arcuately arranged pole segments arranged arcuately the axis. The rotor further includes a plurality of arcuately arranged magnets alternating with the pole segments, such that each of the magnets is at least in part interposed between a pair of adjacent pole segments. Still further, the rotor includes a support structure at least in part supporting the pole segments. The core further includes a plurality of bridges. Each of the bridges extends between and interconnects a corresponding one of the pole segments to the support structure. Each of the bridges includes a plurality of axially spaced apart bridge segments.

摘要： An electric motor comprising a rotor rotatable about a rotor axis and a stator at least substantially circumscribing the rotor is provided. The stator includes a generally toroidal core including a plurality of arcuately spaced apart, radially inwardly extending teeth. Each of the teeth presents a radially innermost face that extends along a curved contour. A portion of the contour has a radius of curvature that corresponds to a circle having a center. The center is radially offset from the rotor axis. Furthermore, each of the teeth includes a radially extending arm having an end and a crown extending relative to the end. The crown presents a pair of arcuately spaced apart endmost tips, each of which has a rotor-facing side. The rotor-facing side includes a tapered portion that turns away from the rotor.

摘要： A motor assembly includes a stator, a rotor rotatable about an axis, and a housing at least in part defining a motor chamber. The stator and the rotor at least in part are received within the motor chamber. The housing includes a first housing portion and a second housing portion. The housing portions engage one another along an interface. The interface restricts ingress of contaminants therethrough into the motor chamber. The housing portions cooperatively define a nested portion that at least in part defines the interface. The nested portion includes an arcuately extending projection and an arcuately extending receiver. The receiver defines an arcuately extending receiving channel. The projection is at least in part received within the receiving channel.
