摘要： 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.

摘要： An electronics package for an alternator includes a positive carrier member having an inner side and an outer side, a plurality of switches connected to the positive carrier member, and a terminal assembly engaging the positive carrier member. The terminal assembly includes an electrically insulative portion and a plurality of electrical traces attached to the electrically insulative portion. The electrically insulative portion includes a post extending from the inner side to the outer side of the positive carrier member, a first shoulder engaging the outer side of the positive carrier member, and a second shoulder engaging the inner side of the positive carrier member. The second shoulder is provided by a deformed segment of the post. The post, first shoulder, and second shoulder are all formed as a unitary component.

摘要： 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.

摘要： A method of making an electronics package for an alternator includes inserting a post of a terminal assembly thorough a hole in an electrically conductive carrier member such that the terminal assembly is positioned on a first side of the carrier member and an end portion of the post extends from a second side of the carrier member. The method further includes deforming the post extending through the hole on the second side of the carrier member such that the terminal assembly engages the second side of the carrier member and the carrier member is connected to the terminal assembly.
