20100008797 | ELECTRIC PUMP UNIT AND ELECTRIC OIL PUMP - An electric pump unit which comprises an outer rotor having a trochoidal tooth profile and an inner rotor which meshes with the outer rotor in such a state the inner rotor and the outer rotor are placed eccentric relative to each other for rotation and also comprises a pump part which is accommodated in a bottomed cylindrical pump housing. A low pressure portion and a high pressure portion are formed by both the rotors, and oil is made to be sucked and discharged through an inlet port and an outlet port which communicate respectively with the low pressure portion and the high pressure portion. A relief valve is provided for circulating oil from the high pressure portion to the low pressure portion when an oil pressure at the high pressure side reaches or exceeds a predetermined pressure. | 01-14-2010 |
20100040488 | MOTOR AND ELECTRIC PUMP - In a motor comprising a stator and a rotor disposed in an inner circumference of the stator, the stator comprises a substantially cylindrical stator core and coils made up of wound conductors, and the stator core comprises an outer circumferential portion which constitutes an outer circumferential wall of the stator and an inner circumferential portion round which the conductors are wound. The outer circumferential portion is formed of a first sintered metal made of a powder magnetic material, while the inner circumferential portion is formed of a second sintered metal made of a powder magnetic material, and the first sintered metal is a sintered metal having a higher mechanical strength than the second sintered metal. Additionally, the stator core is formed by diffusion bonding the outer circumferential portion and the inner circumferential portion being bonded together. | 02-18-2010 |

20120144942 | TRANSMISSION - A transmission that is able to perform shift operation and select operation using the driving force of a single electric motor is provided. A shift/select actuating device includes: an electric motor; a first conversion mechanism; a second conversion mechanism; and a changing unit that changes a destination, to which the rotational driving force of the electric motor is transmitted, between the first conversion mechanism and the second conversion mechanism. The changing unit includes: a first electromagnetic clutch that transmits the rotational driving force of the electric motor to the first conversion mechanism or interrupts the rotational driving force; and a second electromagnetic clutch that transmits the rotational driving force to the second conversion mechanism or interrupts the rotational driving force. | 06-14-2012 |

20130008279 | TRANSMISSION DRIVING DEVICE - A transmission driving device that is capable of preventing displacement of a shift operation member or a select operation member in a case where there is reverse input in the shift operation member or the select operation member by inhibiting rotation of a rotation member which is released from an input shaft. When an input shaft and a first rotor are connected, the first electromagnetic coil is an excitation state and a second electromagnetic coil is in a non-excitation state. In this state, a second magnetic ring is not attracted to the side of the second electromagnetic coil, a seventh facing, which is fixed to the second magnetic ring, and an eighth facing are engaged with each other, and a second rotor and a casing are connected to each other. In a connection state of the second rotor and the casing, the second rotor cannot be rotated. | 01-10-2013 |

20140041468 | ELECTRIC ACTUATOR - An electric actuator includes: an electric motor that includes an output shaft and generates a rotational driving force; shift and select conversion mechanisms that transmit the rotational driving force to a shift select shaft; a transmission shaft that transmits the rotational driving force to the shift and select conversion mechanisms; and a coupling that is provided coaxially with the output shaft and the transmission shaft and connects the output shaft to the transmission shaft so that the output shaft and the transmission shaft are rotatable together. The electric actuator includes a resolver that detects a rotation angle of the output shaft, with regard to the electric motor. A resolver rotor of the resolver is fitted to an outer periphery of a transmission shaft-side cylindrical portion of the coupling. | 02-13-2014 |
20150239492 | VEHICLE STEERING DEVICE, FAILURE DETERMINATION METHOD FOR VEHICLE STEERING DEVICE, AND CONTROL METHOD FOR STEERING MOTOR - A vehicle steering device includes: a steering mechanism that steers steered wheels by driving of a steering motor according to operation of an operation unit; a motor angle sensor that detects a rotation angle of the steering motor as an electrical angle; a steered angle sensor that detects a steered angle of the steered wheels; a storage unit in which correspondence between the electrical angle and the steered angle that are detected is stored in advance; and a failure determination unit that determines whether there is a failure or not by comparing the relation between the detected electrical angle and the detected steered angle with the correspondence between the electrical angle and the steered angle that is stored in the storage unit. | 08-27-2015 |
