Abstract: An electric machine includes windings, a terminal block, and terminal connectors. The windings have lead ends and neutral ends. The terminal block has a plurality of bus bars, a neutral bar, and an insulating material. Each bus bar is connected to one or more of the lead ends. The neutral bar is connected to one or more of the neutral ends. The insulating material encapsulates the plurality of bus bars and the neutral bar, defines a plurality of orifices, and defines a plurality of slots. Each lead end extends through one of the orifices from the outer boundary to one of the bus bars. Each neutral end extends through one of the orifices from the outer boundary to neutral bar. Each terminal connector extends through one of the slots from the outer boundary to one of the bus bars.

Abstract: A motor includes a stator core and a stator booster. The stator booster includes a booster back-iron and a plurality of booster teeth. The booster back-iron includes a first end surface that abuts a first end surface of the stator core's back-iron for electrical communication therewith. The booster teeth extend radially inward from the booster back-iron and are spaced apart from one another in a circumferential direction about the central axis to define a plurality of booster slots that align with slots of the stator core. A first end surface of each booster tooth abuts a first end surface of a corresponding tooth of the stator core for electrical communication therewith. An electrically insulating material encapsulates opposite sides of each booster tooth that define the booster slots and a second end surface of each booster tooth that is opposite the first end surface of that booster tooth.
