Patent number: 6853104Abstract: A miniature motor includes a closed-bottomed cylindrical motor casing having a cylindrical bearing support portion projecting from a central portion of the bottom of the motor casing, a motor-casing-side bearing accommodated in the bearing support portion, a casing cover fitted to an open end portion of the motor casing, a casing-cover-side bearing accommodated in a central portion of the casing cover, and a rotor rotatably supported by means of the motor-casing-side bearing and the casing-cover-side bearing. The end face of the motor-casing-side bearing is concentrically polished at at least a portion which, when the rotor is urged toward the motor casing, abuts a washer provided on a shaft of the rotor. The above structure reduces sliding loss on the end face of an oil-impregnated bearing which receives a thrust load of the rotor generated due to rotation of the motor.Type: GrantFiled: January 29, 2003Date of Patent: February 8, 2005Assignee: Mabuchi Motor Co., Ltd.Inventors: Kenji Shiraki, Hideki Itaya

Patent number: 6853102Abstract: A turntable-integrated spindle motor according to the present invention is constituted by a stator and a rotor. The rotor is constituted by a shaft 4 supported in a bearing in a cantilever support manner, a metallic rotor case 1 fixed to the shaft 4 by a boss 3, and a magnet 10 fixed to an inner circumferential surface of the rotor case 1. A plurality of projections 2 are formed integrally with the metallic rotor case so as to project from the side surface of the metallic rotor case, the projections being arranged along one circumferential line. The projections 2 perform a coming-off-prevention function by engaging with an engaging portion of a chassis 15. The rotor case 1 also functions as a turntable. In the present invention, the motor and the turntable are combined integrally with each other to obtain improved characteristics as well as to reduce the overall height. Also, projections for preventing coming off are formed integrally with the metallic rotor case to ensure high strength of the projections.Type: GrantFiled: May 21, 2003Date of Patent: February 8, 2005Assignee: Mabuchi Motor Co., Ltd.Inventors: Hideki Itaya, Kunio Hiromasa, Mitsuo Fujimoto

Publication number: 20040007929Abstract: A motor in which an attracting magnet for attraction between a rotor and a stator is used in the present invention. The attracting magnet is formed into a hollow cylindrical shape such as to have two flat surfaces between which a predetermined thickness is defined. The attracting magnet is magnetized so as to have different polarities at the inner and outer circumference sides divided in the radial direction in each of its two flat surfaces, and to be reversed in polarity in an interchanging manner between its two flat surfaces. The attracting magnet is mounted on an inner surface of a rotor case while being opposed to a bearing housing. In this motor using the attracting magnet arrangement, the shaft is not magnetized even though the attracting magnet for attraction of the rotor toward the stator is used.Type: ApplicationFiled: May 21, 2003Publication date: January 15, 2004Inventors: Tadayuki Wakita, Nobuyuki Sata, Hisashi Ogino, Shinji Furukawa, Kazuo Kadooka, Hideki Itaya
