Abstract:
A motor includes a stator, a rotor, and a case. The stator includes a stator core and windings. The rotor is provided inside the stator. The rotor includes first and second rotor cores and a field magnet. The first and second rotor cores each includes a core base and claw-shaped magnetic poles. The core bases are opposed to each other and the claw-shaped magnetic poles of the first and second rotor cores are alternately disposed in a circumferential direction. The field magnet is disposed between the core bases in the axial direction. The field magnet is magnetized in the axial direction so as to cause the claw-shaped magnetic poles of the first rotor core and the second rotor core to function respectively as first magnetic poles and second magnetic poles. At least part of an end part of the case in the axial direction is made of a non-magnetic body.
