Patent number: 7650682Abstract: In a state in which a first divisional core and a second divisional core are arranged in a state spaced from each other and adjacent to each other, a first coil and a second coil are each wound around a tooth. The first coil and the second coil are in the same phase. In a state in which a plurality of divisional cores are arranged annularly so that their teeth are oriented in a radially inward direction, the first divisional core and the second divisional core are not adjacent to each other in the circumferential direction. A plurality of connection wires are shaped to converge at an end surface of a stator core. This facilitates the winding of the coils around the divisional cores. Further, the connection wires can be shortened.Type: GrantFiled: February 7, 2007Date of Patent: January 26, 2010Assignee: Asmo Co., LtdInventors: Kazushi Sugishima, Akihiro Suzuki

Publication number: 20080231137Abstract: A coil of a winding is wound around teeth of an armature core for a predetermined number of times in a motor. A start lead of the winding connects between the coil and a corresponding start segment among a plurality of segments of a commutator. A finish lead of the winding connects between the coil and a corresponding finish segment among the plurality of segments. The finish segment is located adjacent to a diametrically opposed one of the plurality of segments, which is circumferentially displaced by about 180 degrees from the start segment and is thereby diametrically opposed to the start segment.Type: ApplicationFiled: February 29, 2008Publication date: September 25, 2008Applicant: ASMO CO., LTD.Inventors: Kazushi Sugishima, Toshihiro Tanino
