Abstract

An alternator including a housing, and a stator fixedly mounted relative to the housing. The stator includes a plurality of stator slots and a stator winding arranged in the plurality of stator slots. The stator winding includes at least five stator leads extending from five adjacent ones of the plurality of stator slots. A terminal assembly is mounted to an outer surface of the housing and is connected with at least three of the at least five stator leads. The terminal assembly includes a body formed from a non-electrically conductive material and a plurality of conductive members at least partially covered by the body. The plurality of conductive members is associated with the stator winding. Each of the plurality of conductive members includes a plurality of input connectors spread out along the body in an arc that is greater than 90°.
