An interconnection assembly has phase parts for U phase, V phase and W phase. The phase parts each are of a plurality of interconnection assembly parts that are connected in the form of a ring and include a conductor section to which a motor coil wire is connected, the conductor section being formed by stripping fluororesin insulation at a predetermined position, and the phase parts are partially fixedly bundled.

There are provided as drive sources an engine, a front motorprovided on a front wheelsside of the vehicle and a rear motorprovided on a rear wheelsside of the vehicle, and in executing a regeneration of deceleration energy when braking, a regeneration capacity of the front motorand a regeneration capacity of the rear motorare calculated, respectively, so that the regeneration is executed with either of these motorswhich can provide a larger regeneration capacity.

Driving force control system for hybrid vehicle

The charging system for a vehicle includes: a motor generator which operates as a generator to generate an alternating current when the motor generator is driven by an internal combustion engine, and operates as a motor when an alternating current is supplied thereto; a switching circuit for converting the alternating current generated by the motor generator into a direct current; a first accumulator accumulating therein the direct current converted by the switching circuit; a second accumulator accumulating therein the direct current converted by the switching circuit and having a smaller accumulation voltage than that of the first accumulator; a first opening/closing unit interposed between the first accumulator and the switching circuit; a second opening/closing unit interposed between the second accumulator and the switching circuit; and, a control unit for controlling the opening and closing of the first and second opening/closing units.

Charging system for vehicle

An electric vehicle in which driving force of a motor driven by batteries is transmitted through a reduction device and a differential to front wheels. The motor and the reduction device are disposed at portions of a vehicle body rearwardly of the differential and hence, a portion of the vehicle body in front of the differential is enlarged and can effectively function as a crushable zone upon a frontal collision of a vehicle. Moreover, the motor and the reduction device which are heavy components are disposed near a central portion of the vehicle body, leading to a mid-ship layout. This conrtibutes to an enhancement in motional property of the vehicle.

An outer rotor type brushless direct current motor has an outer rotor including a plurality of permanent magnets attached along the inner circumference of an annular yoke such that the magnetic poles face the S magnetic poles. Thin sections are formed by chamfering the radially outer periphery of the two end sections in the circumferential direction of each of the permanent magnets. Magnetic flux passage sections of the yoke providing connection between the thin sections of adjacent permanent magnets are expanded radially inwards. In accordance with the above-mentioned arrangement, the cross section of the magnetic path in the magnetic flux passage sections is increased, thereby suppressing the occurrence of magnetic saturation and preventing the maximum torque of the permanent magnets from decreasing while reducing their size. Moreover, because the magnetic flux passage sections of the yoke are expanded radially inwards, the external dimensions of the yoke do not increase.
