Patent number: 6166468Abstract: The object of the present invention is to provide a rotary electric machine which has high assembly accuracy, high heat dissipating efficiency, and excellent durability at the bearing portion. A motor comprises a case, a stator secured within the case, and a rotor formed into one piece with a rotary shaft. The case is provided, on both end faces, with flanges, and one of the flanges is provided with a ball bearing. A stator is radially secured within the case, resin is filled in between the stator and the case with a space of the rotor being left, and a bearing housing and a boss are formed on one side. An open portion is formed in between ribs of the bearing housing, and inserting the bearing into the bearing housing causes a part of the bearing to be exposed through the open portion to fixedly contact with the flange. This allows supporting the bearing securely, and allows frictional heat generated, and the like, to dissipate to the outside via the flange.Type: GrantFiled: August 3, 1999Date of Patent: December 26, 2000Assignee: Minebea Co., Ltd.Inventors: Yuzuru Suzuki, Sakae Fujitani, Kunitake Matsushita, Takayuki Yamawaki, Hiroshi Sano, Kazuo Muramatsu, Taichi Nishio
