Patent number: 10164487Abstract: A motor includes a rotation shaft, a stator, and a rotor. The stator includes an armature winding and a stator core including a main core portion with an axial stack of core sheets and a magnetic plate on an end thereof. Each core sheet includes a tooth formation portion around which the armature winding is wound. The magnetic plate includes a stacked portion and an axially extending portion. The stacked portion stacked on the axial end of the main core portion and includes an end located toward the rotor. The axially extending portion extends toward the outer side in the axial direction from the end of the stacked portion located toward the rotor and is opposed to the rotor in a radial direction of the motor. The axially extending portion is shaped to be magnetically skewed in a circumferential direction relative to the tooth formation portion and the stacked portion.Type: GrantFiled: January 23, 2014Date of Patent: December 25, 2018Assignee: ASMO CO., LTD.Inventors: Tatsunori Banba, Hiroshi Katai, Yuusuke Tateishi, Yuuji Yamashita, Takumi Suzuki, Kenji Obata, Yoshimasa Kinpara, Takashi Nagaya

Patent number: 9502939Abstract: A method for manufacturing a stator configured to ensure insulation properties between a conductor and an armature core while preventing a manufacturing cost from increasing and preventing a space factor from lowering. In an edge-removing step, a plurality of independent edge-removing punches, which correspond to one slot S or two or more slots S, press and chamfer a corner portion of an axial opening edge of the slot in an axial end core sheet of the armature core.Type: GrantFiled: June 22, 2012Date of Patent: November 22, 2016Assignees: ASMO CO., LTD., DENSO CORPORATIONInventors: Yoshimasa Kinpara, Takahiro Yamamoto, Jirou Hayashi, Asuka Tanaka

Patent number: 8957562Abstract: A stator includes a core having a plurality of slots and a plurality of U-shaped conductors, which are inserted in the corresponding slots. Each of the conductors has a pair of legs and a joint portion that connects the legs together. Each slot receives four legs and each of the legs in the slot is one leg of the corresponding one of the conductors. Two of the four conductors corresponding to the four legs inserted in each slot are overlapped with each other at the joint portions as viewed at least circumferentially.Type: GrantFiled: June 18, 2012Date of Patent: February 17, 2015Assignee: Asmo Co., Ltd.Inventors: Yoshimasa Kinpara, Noriyasu Nishio, Teruhisa Tateiwa, Takenobu Kawakami

Patent number: 8890387Abstract: An armature core of a stator has an annular portion and a plurality of teeth extending radially from the annular portion. A segment coil is configured by electrically connecting a plurality of segment conductors together. The segment conductors extend axially through slots S, each of which is defined between each adjacent pair of the teeth. Each of the teeth has a width adjustment portion for decreasing a slot width in a direction perpendicular to a radial direction in the radially inward direction.Type: GrantFiled: June 18, 2012Date of Patent: November 18, 2014Assignee: Asmo Co., Ltd.Inventors: Yoshimasa Kinpara, Noriyasu Nishio, Takahiro Yamamoto

Publication number: 20120326550Abstract: A stator manufacturing method includes the steps of preparing an armature core, forming an insulating member including two opposing portions from a sheet-like insulating material, and deforming the insulating member to move the two opposing portions toward each other. The method also includes the step of inserting distal parts of the two opposing portions into the corresponding slit from the axial direction thereby covering an inner surface of each of the slot with the insulating member. Further, the method includes the steps of inserting a conductor forming a winding into each of the slots between the two opposing portions.Type: ApplicationFiled: June 22, 2012Publication date: December 27, 2012Applicant: ASMO CO., LTD.Inventors: Yoshimasa KINPARA, Yasuhiro KANEMATSU

Publication number: 20120080973Abstract: A laminated core includes laminated core sheets each formed by press working. Each core sheet has a teeth portion corresponding to the teeth. An insulating film covers at least a portion of the laminated core corresponding to the teeth. A burr caused by the press working in each core sheet is located on a side of one end of the laminated core in a laminating direction of the laminated core. The burr of the teeth portion of one of the core sheets located at the one end is folded toward the other end of the laminated core in the laminating direction.Type: ApplicationFiled: September 27, 2011Publication date: April 5, 2012Applicant: ASMO CO., LTD.Inventors: Yuya FURUKAWA, Yoshimasa Kinpara
