Abstract: A synchronous reluctance motor includes a stator and a rotor. The rotor is configured to rotate relative to the stator about a rotational axis. The rotor is spaced apart from the stator to define an air gap between the stator and the rotor and includes a rotor core defines an outermost rotor surface and an innermost rotor surface opposite the innermost rotor surface. The rotor core includes a plurality of ribs separating rotor cavities from each other and includes a plurality of rotor bridges separating the air gap and the rotor cavities. Permanent magnets are each disposed in one of the rotor cavities. The magnet surface area of the permanent magnets is less than cavity surface area of the rotor cavities. Each of the permanent magnets is adjacent to the outermost rotor surface to maximize magnetic saturation at the ribs and the rotor bridges.

Abstract: An electrical system includes an alternating current (AC) connector rod assembly and a polyphase electric machine. The electric machine has a plurality of phase leads each electrically connected to the AC connector rod assembly. The assembly includes spaced AC connector rods each having a center axis. The assembly also includes insulating housings and a carrier plate defining through holes that receive and space the AC connector rods. The carrier plate defines features that engage mating features of the insulating housings while allowing each of the rods to rotate about its respective center axis within the carrier plate. A vehicle includes a direct current (DC) battery pack, a DC bus, an AC bus, a PIM that is electrically connected on a first side to the DC bus and on a second side to the AC bus, the AC connector rod assembly, a traction motor, and a transmission.
