Patent number: 10505407Abstract: A brushless motor comprising: a rotor; a stator core disposed at a radial direction outside of the rotor, and a stator case. The stator core includes an outer ring shaped section, teeth sections projecting out from the outer ring shaped section toward a radial direction inside, and an inner ring shaped section extending from end portions of the teeth sections. Protruding portions are formed at the outer ring shaped section so as to project toward a radial direction outside and so as to be disposed at even intervals around a circumferential direction of the outer ring shaped section. The stator case is integrated together with the stator core by a plurality of plastic deformation portions formed at an outer peripheral portion of the stator case at locations facing towards the protruding portions, and the plastic deformation portions are disposed at even intervals along a circumferential direction of the stator case.Type: GrantFiled: February 8, 2017Date of Patent: December 10, 2019Assignee: DENSO CORPORATIONInventors: Yoshinobu Nagao, Satoru Suzuki, Takashi Nagaya, Yoshihiro Adachi, Yukihide Ishino, Yoshitsugu Nakagawa, Masaru Irie, Toshihiro Matsuura

Patent number: 9209669Abstract: A method for manufacturing a stator includes preparing a stator core having a plurality of teeth, a plurality of coils having a plurality of lead lines, a substrate having a plurality of connecting portions, and a plurality of positioning jigs having restraining portions. The method includes positioning the substrate and the lead lines so that distal portions of the lead lines are separated from the connecting portions in at least one of a radial direction and a circumferential direction. The method further includes inserting the lead lines in the restraining portions, aligning the distal portions of the lead lines with the corresponding connecting portions using the positioning jigs, inserting the lead lines into the corresponding connecting portions, and electrically connecting the lead lines inserted in the connecting portions to the corresponding connecting portions.Type: GrantFiled: December 21, 2012Date of Patent: December 8, 2015Assignee: ASMO CO., LTD.Inventors: Hiroyuki Mizutani, Yoshitsugu Nakagawa, Yukihide Ishino

Patent number: 8963395Abstract: An annular motor core has a plurality of split core pieces, each of which includes a yoke portion and a tooth. The split core pieces are circumferentially located and arranged in an annular shape such that the yoke portions of the core pieces form an annular shape as a whole and that the distal ends of the teeth of the core pieces face inward or outward each in a radial direction of the core. The core further includes an annular holder, which has joint portions at a plurality of positions in a circumferential direction of the holder. A first end of each of the core pieces is pivotably joined to the corresponding one of the joint portions. Each core piece can be pivoted about the corresponding joint portion relative to the holder such that a second end of the core piece moves in a radial direction of the holder.Type: GrantFiled: May 22, 2012Date of Patent: February 24, 2015Assignee: Asmo Co., Ltd.Inventors: Yukihide Ishino, Akitomo Sasaki, Akihiro Utsumi, Toshiaki Yamada
