发明名称 Electric motor having resilient member and apparatus for manufacturing the same
摘要 An electric motor includes a housing that receives multiple magnets that are circumferentially arranged in the housing. A resilient member has two inserted portions that are respectively inserted into gaps formed among the magnets. For example, four inserted portions of the two resilient members are respectively inserted into four gaps formed among four magnets, so that the inserted portions are resiliently deformed in the gaps. The inserted portions apply force to the magnets such that the magnets are circumferentially spaced from each other. Thus, the four magnets are urged onto an inner wall of the housing by the two resilient members. As a result, movement of the magnets is restricted in both of the circumferential direction and the axial direction of the housing. Therefore, the magnets can be maintained in the housing using a simple structure without increasing the number of components.
