Patent number: 8461734Abstract: Winding start sections and winding end sections of winding wires are pulled out from slots of an armature core and are guided by wire guides of an insulator. Thereafter, each corresponding one of the winding start sections and the winding end sections is guided by a corresponding winding holding portion and is directly connected to a corresponding one of power supply terminal elements of a circuit apparatus without using an intermediate terminal.Type: GrantFiled: May 20, 2010Date of Patent: June 11, 2013Assignee: ASMO Co., Ltd.Inventors: Yoshimichi Sahara, Masato Ooishi, Tatsuya Kawai

Patent number: 7859155Abstract: A second ball bearing is installed from a first axial side toward a second axial side into an interior of a bearing holder of a rotor through an opening of the bearing holder, so that an outer race of the second ball bearing is press fitted to an inner peripheral portion of the interior of the bearing holder. A first ball bearing is inserted from the first axial side toward the second axial side into the interior of the bearing holder of the rotor through the opening of the bearing holder after the installing of the second ball bearing, so that an outer race of the first ball bearing is press fitted to the inner peripheral portion of the interior of the bearing holder and is axially spaced from the outer race of the second ball bearing.Type: GrantFiled: July 30, 2010Date of Patent: December 28, 2010Assignee: ASMO Co., Ltd.Inventors: Yoshimichi Sahara, Masato Ooishi, Tatsuya Kawai, Bungo Mizutani
