    摘要: A stator assembly for an electric motor includes a stator housing, a flux ring inserted into the stator housing after the stator housing is formed and a plurality of magnets on an inner surface of the flux ring. Overmold material is molded around the magnets in the flux ring, such as by injection molding. The overmold material secures the magnets to the flux ring and the flux ring to the housing. In an aspect, the overmold material is molded to form at least one of a commutator end or rear bearing support, front bearing support and fan baffle.

    摘要: A stator assembly for an electric motor includes a stator housing, an expandable flux ring inserted into the stator housing and a plurality of magnets on an inner surface of the flux ring. Overmold material is molded around the magnets in the flux ring, such as by injection molding. The pressure of the overmold material as it is being molded expands the flux ring pressing the flux ring into engagement with the stator housing. The overmold material secures the magnets to the flux ring and the flux ring to the housing. One of the flux ring and stator housing has a dimple that engages a hole in the other of the flux ring and stator housing to align the flux ring and stator housing. In an aspect, the overmold material is molded to form at least one of a commutator end or rear bearing support, front bearing support and fan baffle. In an aspect, the overmold material is molded to form a keying feature. The keying feature can be slots of different widths between magnetic poles of the stator assembly. In an aspect, the flux ring and housing are preformed as a unit by stamping them from blanks and rolling them together. In a variation, the flux ring blank is rolled first to form the flux ring and the housing blank rolled around the flux ring with the flux ring acting as a rolling arbor.

    摘要: An electrically conductive brush box is located against the upper surface of a base and has crimping tabs located against an oppositely disposed crimping surface. The base is formed of high temperature resistant plastic. A field case housing has a seat with a retention member adapted to retain the base against the seat. A screw is threaded into the field case housing such that the head presses against a surface of the base member to retain the base member in the seat. The screw member is located in non-contacting relationship with the electrically conductive brush box. A spacer member is adapted to space the portion of the crimping tab against the crimping surface away from the field case housing. The brush box includes a biasing member holder and the crimping tabs are located adjacent the holder.
