Abstract:
A rotor is provided which includes a first rotor portion, a second rotor portion which is arranged at a position deviated from the first rotor portion by a predetermined skew angle so as to contact the first rotor portion, first magnets each of which is provided in a magnetic pole of the first rotor portion, and second magnets each of which is provided in a magnetic pole of the second rotor portion and is arranged at a position deviated from the first magnet of the first rotor portion by the predetermined skew angle. Coercive field strengths of the first magnets and coercive field strengths of the second magnets are different from each other.
