Abstract: A vehicle drive system includes a motor (drive motor), a generator, a reduction drive that reduces output of the motor, and a housing. At a position above a motor shaft, an oil passage, through which oil is supplied to each of the motor, the reduction drive, and the generator, is integrally formed with the housing. An oil pipe is attached to the housing and supplies the oil from an oil reservoir to the oil passage. At a position between the motor and the generator, the reduction drive is offset from the motor shaft in a second direction that is orthogonal to the first direction. The oil pipe is located between the motor and the generator in the first direction, and at least part of the oil pipe is located on an opposite side of the reduction drive with the motor shaft being interposed therebetween in the second direction.

The mounting bracket includes a front fixing portion and a rear fixing portion to be fixed to the power train. A strength of the front fixing portion and the rear fixing portion is set to such a strength that the rear fixing portion is broken by a collision load from a front side, and the front fixing portion is not broken.

Abstract: In an electric vehicle inverter apparatus 100, a vehicle control controller 15 detects a switch open signal output from a collision detector 16 when the collision detector 16 is caused by a collision between electric vehicles to operate. Then, an inverter main circuit connection switch 10 of a high-voltage battery unit 8 is put into an open state. Thus, the direct-current power supply from a high-voltage battery 12 to a DC bus portion is interrupted. In addition, electric charges charged into a main circuit capacitor 7 are discharged by a forced discharge circuit portion 22b.

Abstract: A hybrid vehicle includes: first and second rotary electric machines; a matrix converter connecting the first and second rotary electric machines to each other to provide AC to AC power conversion between both the rotary electric machines; a battery connected to an electrical path branched off between the matrix converter and the second rotary electric motor; an inverter interposed among the battery, the matrix converter and the second rotary electric machine to convert AC power to DC power and vice versa; and a controller. The controller activates the first rotary electric machine with power fed from the battery and restrains the change in torque output of the second rotary electric machine at the activation of the first rotary electric machine.

Abstract: A stator of a motor is provided with a stator core having a plurality of teeth and a plurality of windings wound around teeth of the stator core. The stator also has an insulator that is provided with a plurality of lead-out guide portions that enable lead-out wires of the windings to be drawn out from the tooth winding portions in a state of being close to the tooth winding portions.

Abstract: An electric motor stator has a stator core and a plurality of windings wound around teeth of the stator core. Each of the windings has two tooth winding portions with a crossover wire extending therebetween. Each of the windings starts from a neutral wire and winds around a first tooth to form a first tooth winding portion and then winds around an opposed tooth to form a second tooth winding portion with the crossover wire extending as a power wire. Thus, the second tooth winding portion is started from the power wire. A terminal end of the second tooth winding portion is drawn out and connected to the neutral wire. The stator core has an insulator having support portions for preventing the tooth winding portions from falling outwards. The power wire is held between the tooth winding portion and a slot bottom so as to be fixed.

Abstract: Disclosed is a motor control method for an electric-powered vehicle (1), which is designed to switch an output characteristic of an electric motor (5) for rotatably driving a driving wheel (16) of the vehicle (1), between a low-speed mode adaptable to a relatively low rotation speed operation region and a high-speed mode adaptable to a relatively high rotation speed operation region, on the basis of a given switching rotation speed (Nt) as a threshold.

Abstract: A compressor has an electric motor element section having a rotor and a stator provided on the outer peripheral side of the rotor. An oil separation plate is installed on an upper end surface of the rotor with an end plate in between. The end plate is provided with a projection. Through-holes in which the projection is fitted are provided in the oil separation plate as a separate plate member installed on the end plate. Portions of the projection that project from the through holes of the oil separation plate are crushed to integrate the oil separation plate and the end plate. A recess is provided in the upper face of the projection, and the recess allows deformation, at the time of the crush, of the projecting portions of the projection.
