  • Publication number: 20160079817
    Abstract: 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.

  • Publication number: 20150314772
    Abstract: 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.

  • Patent number: 8914179
    Abstract: 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.

  • Publication number: 20140232228
    Abstract: 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.

  • Patent number: 6978245
    Abstract: An automatic planning apparatus comprises a WWW server and an application server which are connected to many clients through the Internet. The clients are operated by the users. The application server creates and asks some questions to the user. The user answers the questions. The answers are analyzed to determine the character. Certain initial conditions are input by the user or some other person. The application server automatically creates a schedule for the preparation of an event desired by the users after taking the input initial conditions and the character of the user into consideration.
