摘要： A stator of a dynamo-electric machine which is capable of raising the space factor in each slot and which can easily be assembled incorporates first coil pieces, each of which has a width at the lower portion of the slot being smaller than the width at the upper portion of two slots; and second coil pieces arranged to be fitted to teeth adjacent to the tooth to which the first coil piece is fitted so as to be inserted into the empty space for filling the space. The first and second coil pieces are alternately inserted into the slots of the stator core. The empty space in the slot formed after the first coil piece has been inserted has sides extending parallel with the adjacent tooth or is gradually widened toward the upper portion of the slot. Therefore, the second coil piece can easily be inserted into the slot without interference with another member. Thus, the slots can be filled with the second coil pieces so that the space factor can be raised.

摘要： Front left and right wheel units are driven by an engine and a motor generator. Rear left and right wheel units are independently driven by in-wheel motor type motor generators. The motor generator and the motor generator are configured to have different rated outputs, respectively, and be subjected to different speed reduction ratios, respectively, between the motor generators and their respectively associated drive wheel units, and thus have characteristics, respectively, in efficiency with respect to torque and vehicular speed, that exhibit high efficiency in mutually different output ranges, respectively. When a mileage oriented mode is selected as a traveling mode, an ECU determines how a drive torque should be allocated between the motor generators, as based on the motors' required drive torque and vehicular speed and on each motor generator's characteristic in efficiency, to maximize the motor generators' total efficiency.

摘要： A stator core includes a pressurized powder core section which is produced by compression-molding a magnetic powder covered by an insulation coating. At least a portion of the pressurized powder core section forms at least a part of a winding slot section around which a winding is wrapped. The pressurized powder core section comprises a winding guide groove which prevents the winding from deviating along the extending direction of the winding slot section. As a result, a space factor of the winding can be increased, to thereby further improve motor output.
