Publication number: US20220052573A1
Application number: 17/514,300

Abstract:
An electric machine includes a core with windings positioned on the core. The windings include in-slot portions, end turns, and leads. The in-slot portions are positioned in slots of the core. The end turns extend from the in-slot portions at ends of the core. The leads extend from the in-slot portions and axially past the end turns. A bus bar assembly is positioned radially inward from the end turns. The bus bar assembly includes an arc portion, a plurality of axial lead connectors, and a plurality of axial phase terminals. The arc portion is positioned axially within the end turns. The axial lead connectors extend axially past the end turns and are connected to the leads. The axial phase terminals also extend axially past the end turns.

Publication number: US20220140688A1
Application number: 17/452,166

Abstract:
An electrically-assisted turbocharger includes a shaft extending along an axis, a compressor wheel, a turbine wheel, a housing, and an electric machine. The electric machine includes a rotor rotatably coupled to the shaft and a stator lamination stack radially spaced from the rotor. The stator lamination stack has circumferentially spaced teeth defining gaps therebetween. The electric machine also includes a coil winding disposed in the gaps between the circumferentially spaced teeth and a guard plate disposed at one of the first and second stator ends. The guard plate extends radially away from the axis and includes a plurality of teeth guards extending radially, with each of the teeth guards aligned with one of the teeth of the stator lamination stack to electrically insulate the coil winding from the teeth of the stator lamination stack.

Publication number: US20220029490A1
Application number: 17/496,908

Abstract:
An electric machine includes a stator assembly and a bus bar assembly. The stator assembly includes a core with windings positioned on the core. The windings include in-slot portions, end turns, and leads. The leads extend from the in-slot portions at one of the ends of the core with ends of the leads extending axially past the end turns. The leads include a first plurality of leads positioned on a first side of the stator opposite a second plurality of leads positioned on a second side of the stator. The bus bar is substantially circular in shape and positioned radially inward from the end turns. The bus bar assembly includes three bus bars, each bus bar connecting at least one of the first plurality of leads to at least one of the second plurality of leads.
