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.
