Abstract: A rotor includes first and second rotor cores and a field magnet placed between the first and second rotor cores. Each of the rotor cores has a main body portion and a plurality of extensions, which extend radially outward from the main body portion at equal intervals in the circumferential direction. The field magnet causes the individual extensions to function as magnetic poles. A magnetic pole constituting section including at least part of each of the extensions and the first main body portion of each rotor core are made of different materials, made of the same material but formed as separate elements, or includes regions having different properties.

Abstract: A rotor includes at least one of a group of one or more auxiliary magnets that are located between first and second claw poles in a circumferential direction and magnetized to be magnetic poles of the same polarity as the first and second claw poles and another group of one or more auxiliary magnets that are located on a rear side of the first and second claw poles and magnetized to have radially outer portions of the same polarity as the first and second magnetic poles. The auxiliary magnets are arranged to protrude beyond at least one of axial end surfaces of the first and second core bases.
