摘要： A drive motor for an electrically powered automotive vehicle is provided which includes a motor stator including a magnetic body and coils. The inner peripheral surface of the magnetic body has a plurality of teeth protruding therefrom, around which the coils are wound. The drive motor also includes a motor housing mounted to an outer periphery of the motor stator to retain the motor stator. The outer peripheral surface of the magnetic body includes cutout portion(s) formed at circumferential location(s) thereof, with the circumferential location(s) being at the same phase as those of the teeth. An inner peripheral surface of the motor housing includes engagement portion(s) formed at circumferential location(s) thereof, with the circumferential location(s) being opposed to the cutout portion(s). The engagement portion(s) is/are engageable with the cutout portion(s). The engagement portion(s) and the cutout portion(s) cooperate with each other to form arresting unit(s) for arresting the motor stator.

摘要： An in-wheel motor drive apparatus is provided that facilitates the dissipation of the heat generated by a motor and that is excellent in cooling performance. A range (L) of number of revolutions within which a motor (B) generates a maximum torque by low-speed-rotation includes a high-output sub-zone (LH) in which a torque is no less than 50% of the maximum torque. In the high-output sub-zone, a loss in a stator represents no less than 50% of a loss in the motor (B), with the loss in the motor consisting of copper loss and core loss. The motor (B) may include cooling medium passage(s) (45) configured to cool coil portion(s) (28) of the stator (23) with a cooling liquid, and the copper loss may represent no less than 25% of the loss in the motor (B).
