Disclosed is a motor including a stator having coils and a rotor rotated with respect to the stator, wherein the rotor is provided with a plurality of flux barriers arranged at intervals in a circumferential direction to restrain detouring of magnetic flux in the rotor, a permanent magnet is fitted in each of the flux barriers, and variable magnetic resistance members, magnetic resistance of which increases with increasing temperature, are provided at areas of the rotor closer to the stator than the flux barriers.
