PROBLEM TO BE SOLVED: To provide a motor which enables a wide range operation with compatibility between a high torque and a high rotation (high output) by efficiently enabling intense field control and weak field control, provided with opposed characteristics such as a forward salient-pole characteristic and an inverse salient-pole characteristic. SOLUTION: The motor has: a stator 12 having a coil for a field and teeth for winding the coil, and a rotor 41 having a plurality of permanent magnets 13 and rotatably attached to the stator 12 around an rotation shaft. The permanent magnets 13 are arranged in the perimeter around the rotation shaft so that different magnetic poles are located linearly. The motor is provided between the perimeter of the rotor 41 and the different magnetic poles of the permanent magnets 13, and has a magnetic flux shorting mechanism 43 for changing the amount of shorted magnetic flux inside the rotor 41.
