Abstract

"CONJUNTO DE ESTATOR COM PEçA SOBREMOLDADA QUE PRENDE OS ìMãS A UM ANEL DE FLUXO E O ANEL DE FLUXO AO ALOJAMENTO DE ESTATOR". Um conjunto de estator para um motor elétrico inclui um alojamento de estator, um anel de fluxo expansível inserido no alojamento de estator e uma série de imãs sobre a superfície interna do anel de fluxo. Um material de sobremolde é moldado em volta dos ímãs no anel de fluxo, seja por moldado por injeção, por exemplo. A pressão do material de sobremolde à medida em que é moldado expande o anel de fluxo, pressionando o anel de fluxo no sentido do contato com o alojamento de estator. o material de sobremolde prende os ímãs ao anel de fluxo e o anel de fluxo ao alojamento. Um dos anel de fluxo e alojamento de estator tem uma covinha que entra em contato com um orifício no outro dos anel de fluxo e alojamento de estator de modo a alinhar o anel de fluxo e o alojamento de estator. Sob um aspecto, o material de sobremolde é moldado de modo a se formar pelo menos um de uma extremidade de comutador ou suporte de mancal superior, suporte de mancal anterior e defletor em forma de leque. Sob um aspecto, o material de sobremolde é moldado de modo a formar um recurso de chaveamento. O recurso de chaveamento pode consistir em fendas de diferentes larguras entre os pólos magnéticos do conjunto de estator. Sob um aspecto, o anel de fluxo e o alojamento são pré-moldados como uma unidade ao serem estampados a partir de peças em bruto e laminados um no outro. Em uma variação, a peça em bruto de anel de fluxo é laminada primeiro de modo a se formar o anel de fluxo e a peça em bruto de alojamento laminada em volta do anel de fluxo, com o anelde fluxo atuando como um eixo de laminação."STATOR ASSEMBLY WITH OVERFOLDING PART HOLDING THE MAGNETS TO A FLOW RING AND THE FLOW RING TO THE STATUS ACCOMMODATION". A stator assembly for an electric motor includes a stator housing, an expandable flow ring inserted into the stator housing, and a series of magnets on the inner surface of the flow ring. An overmold material is molded around the magnets in the flow ring, either by injection molding, for example. The pressure of the overmold material as it is molded expands the flow ring by pressing the flow ring in contact with the stator housing. the overmold material attaches the magnets to the flow ring and the flow ring to the housing. One of the flow ring and stator housing has a dimple that contacts a hole in the other of the flow ring and stator housing to align the flow ring and stator housing. In one aspect, the overmould material is molded to form at least one of a commutator end or upper bearing bracket, front bearing bracket and fan-shaped deflector. In one aspect, the overmold material is molded to form a keying feature. The switching feature may consist of slots of different widths between the magnetic poles of the stator assembly. In one aspect, the flow ring and housing are precast as a unit by being stamped from blanks and laminated together. In one variation, the flow ring blank is first laminated to form the flow ring and the housing blank rolled around the flow ring, with the flow ring acting as a rolling axis.
