Patent number: 9780630Abstract: A motor rotor and a method for manufacturing a motor rotor, enabling crimping of the resolver rotor at low cost with less influence on the detection accuracy. A motor rotor includes a resolver rotor and a rotor shaft to which the resolver rotor is affixed by crimping. The rotor shaft includes a first stepped section with which a crimping punch makes contact to deform the first stepped section, a second stepped section with which an end surface of the resolver rotor makes contact, and a cutout groove formed in a surface which is located near the first stepped section and with which an inner peripheral hole section of the resolver rotor makes contact. In the crimping operation, the first stepped section of the rotor shaft is bent within the cutout groove to form a crimping protrusion which presses the end surface of the resolver rotor.Type: GrantFiled: December 16, 2014Date of Patent: October 3, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hideaki Yasuda, Yasuyuki Satake

Patent number: 9130416Abstract: A coil including a first winding portion and a second winding portion arranged on a stator of a rotary electrical machine. The first winding portion is formed by edgewise-winding a conductive rectangular wire. The second winding portion is formed by edgewise-winding a conductive rectangular wire, which is connected to the first winding portion. Coil end parts of the first and second winding portions each include a crank-shaped section. The first and second winding portions are formed so that when slot insertion parts of the first and second windings are arranged in slots of the stator, a long side of a cross-section of the rectangular wire extends in the circumferential direction of the stator and a short side of the cross-section of the rectangular wire extends in a radial direction of the stator.Type: GrantFiled: February 7, 2012Date of Patent: September 8, 2015Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Satoru Baba, Yasuyuki Satake

Patent number: 8901796Abstract: A rotor is provided with a rotor core, a shaft fastening hole provided at the center of the rotor core, and magnets provided to the outer circumferential portion of the rotor core. Circular arc slits are formed at intervals on double concentric circles, respectively, so as to be located around the shaft fastening hole of the rotor core. The slits are arranged in such a manner that the outside slits on the outer circle are each located so as to block the portions located in the intervals between adjacent inside slits on the inner circle.Type: GrantFiled: December 23, 2009Date of Patent: December 2, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masayuki Matsushita, Yasuyuki Satake
