Abstract: An attachment structure for a vehicle motor is applied for the purpose of attaching a vehicle motor to in-vehicle equipment. The attachment structure for a vehicle motor is provided with an axial gap motor that includes a rotor and a stator facing each other in the axial direction. The motor is attached to the in-vehicle equipment in a mode in which the axial direction is perpendicular to the vertical direction.

Abstract: A motor includes a stator, a rotor, a case, and back-surface magnet portions. The rotor has a first rotor core, a second rotor core and a field magnet. Each of the first and second rotor cores has a core base and claw-shaped magnetic poles. The field magnet is sandwiched between the first rotor core and the second rotor core and causes the claw-shaped magnetic poles of the first rotor core and the second rotor core to function as different magnetic poles. The back-surface magnet portions include a second and a first back-surface magnet portions respectively provided on the back surfaces of the claw-shaped magnetic poles of the second rotor core and the first rotor core. Size of the second back-surface magnet portion differs from size of the first back-surface magnet portion are different from each other.
