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.
摘要翻译：用于电动机的定子组件包括定子壳体，插入定子壳体中的可扩展磁通环和在磁通环内表面上的多个磁体。包覆模制材料围绕磁通环中的磁体模制，例如通过注塑成型。包覆成型材料在被模制时的压力使得将磁通环压紧的磁通环与定子壳体接合。包覆成型材料将磁体固定到磁通环和磁通环到壳体。磁通环和定子壳体中的一个具有与磁通环和定子壳体中的另一个中的孔接合的凹坑，以对准磁通环和定子壳体。一方面，二次模塑材料被模制以形成换向器端部或后轴承支撑件，前轴承支撑件和风扇挡板中的至少一个。在一个方面，模塑包覆成型材料以形成键合特征。键合特征可以是定子组件的磁极之间的不同宽度的槽。在一方面，磁通环和壳体通过将它们从坯件冲压并将它们一起滚压而作为单元预成型。在一个变型中，首先滚动磁通环坯料以形成磁通环，并且壳体坯料围绕磁通环卷绕，磁通环用作滚动心轴。
