Publication number: 20160079817Abstract: This rotor for a rotating electric motor includes a hollow cylindrical rotor core with a plurality of laminated electromagnetic steel plates. The inner and outer circumferential surfaces of the rotor core each face a magnetic gap. The rotor core is interposed between a first rotating support member and a second rotating support member. A flange is formed on a first end of a tubular pin protruding from a first hole of the first rotating support member. A tubular expansion part of the tubular pin plastically deforms due to fluid pressure so as to come into close contact with a through hole of the rotor core, the first hole of the first rotating support member, and a second hole of the second rotating support member.Type: ApplicationFiled: January 21, 2014Publication date: March 17, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hirohito HAYASHI, Takahiro SHINA, Masahide UEMURA, Akira MURAKAMI, Tomoyuki TOHYAMA, Eiji TSUCHIYA, Yasumitsu OSADA, Wataru HIJIKATA, Takao WATANABE

Publication number: 20150314772Abstract: When a drive shaft (37) is driven while the operation of an engine (36) is stopped, the rotation of an input-side rotor (28) is restricted by the engagement of a brake. Further, on the basis of the temperature Temp_SR of a brush (96) acquired by a temperature sensor (97), the distribution of torque Tcoup acting between the input-side rotor (28) and the first output-side rotor (18) and torque Tmg acting between the stator (16) and the second output-side rotor (19) is controlled. Consequently, drive performance when the drive shaft (37) is driven while the operation of the engine (36) is stopped is improved while local overheating of a slip ring (95) is prevented.Type: ApplicationFiled: November 8, 2013Publication date: November 5, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takao WATANABE, Eiji TSUCHIYA, Tatsuya MIYANO, Akira MURAKAMI, Takahiro SHINA, Tadashi FUJIYOSHI

Patent number: 8914179Abstract: During an inertial energy storage operation, electric power conversion at an inverter is controlled such that a direct current electric power from an electric power storage device is converted into an alternating current by the inverter so as to be supplied to stator windings, such that torque in the direction of engine rotation is applied to an output side rotor from a stator to rotatively drive the output side rotor in a state where power transmission from the output side rotor to a drive axle is stopped. During a cranking operation after the inertial energy storage operation, the electric power conversion at an inverter is controlled to permit application of the alternating current to rotor windings, such that a torque in the direction of engine rotation is applied to an input side rotor from the output side rotor, thereby rotatively driving an input side rotor to crank the engine.Type: GrantFiled: March 27, 2012Date of Patent: December 16, 2014Assignees: Kabushiki Kaisha Toyota Chuo Kenkyusho, Toyota Jidosha Kabushiki Kaisha, Aisin Seiki Kabushiki KaishaInventors: Eiji Tsuchiya, Takao Watanabe, Shu Asami, Tatsuya Miyano, Akira Murakami, Hiroyuki Ogawa, Tomoyuki Toyama

Publication number: 20140232228Abstract: A rotational difference is generated between a first and a second rotor and a third rotor, which causes an induced current to flow in a first rotor winding. This causes a torque to act between the first rotor and the third rotor. The rotary magnetic field generated by the induced current flowing through a second rotor winding interacts with a second stator, which in turn generates an induced electromotive force in a second stator winding. The induced electromotive force is applied via a phase adjustment circuit to a first stator winding, which generates a rotary magnetic field and causes a torque to act between the first stator and the third rotor. The rotary magnetic field generated by the second rotor winding and the induced current flowing in the second stator winding causes a torque to act between the second stator and the second rotor.Type: ApplicationFiled: April 29, 2014Publication date: August 21, 2014Applicants: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takao WATANABE, Eiji TSUCHIYA, Hiroyuki NISHIZAWA, Takeshi KITAHATA
