Patent number: 10090723Abstract: A three phase stator configured with phases that are U-phase, V-phase, and W-phase. The stator is configured such that a bus bar portion includes a joint that is formed at an end and is joined to a terminal portion of a different one of the coils. A connecting portion is formed between the joint portion and the winding portion. In the coils, a first coil and a second coil serve as the two coils joined to each other by the joint portion of the bus bar portion of the first coil and the terminal portion of the second coil, and ends of the terminal portions of middle coils are the coils disposed between the first coil and the second coil are located at a height closer to the stator core than the connecting portion of the first coil in a direction of a central axis of the stator core.Type: GrantFiled: April 18, 2013Date of Patent: October 2, 2018Assignees: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KASHAInventors: Shingo Hashimoto, Hiroyuki Tanaka, Takanori Ota, Shingo Sato, Daichi Kurashige, Hirotaka Kawaura, Norihiko Akao

Patent number: 9837869Abstract: A stator configured with an annular stator core, and a plurality of coils mounted on the stator core. The bus bar portion being connected to the terminal portion of a different one of the coils of the same phase. The coil is a multi-layer coil that is formed by winding the conductor in a plurality of layers in an inside-outside direction of loops in the winding portion, and that includes on inner and outer peripheral sides of a coil end portion of the coil a plurality of lane change portions formed by the conductor. The bus bar portion is embedded in a clearance between the lane change portions of the coil of a different phase placed between the coils of the same phase which are connected to each other.Type: GrantFiled: June 28, 2013Date of Patent: December 5, 2017Assignees: AISIN AW CO., LTD., TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Shingo Hashimoto, Hiroyuki Tanaka, Takanori Ota, Shingo Sato, Daichi Kurashige, Hirotaka Kawaura, Norihiko Akao

Publication number: 20150123503Abstract: A stator configured with an annular stator core, and a plurality of coils mounted on the stator core and each including a winding portion formed by winding a rectangular conductor in a loop shape, a bus bar portion extended from one end in a radial direction of the stator core in the winding portion, and a terminal portion extended from the other end in the radial direction of the stator core in the winding portion. A bus bar portion is formed so that a longitudinal direction extends perpendicularly to a direction of a central axis of the stator core. The terminal portion is formed so that the longitudinal direction extends perpendicularly to the direction of the central axis of the stator core. The bus bar portion is joined to the terminal portion of a different one of the coils.Type: ApplicationFiled: June 28, 2013Publication date: May 7, 2015Inventors: Shingo Hashimoto, Hiroyuki Tanaka, Takanori Ota, Shingo Sato, Daichi Kurashige, Hirotaka Kawaura, Norihiko Akao
