PROBLEM TO BE SOLVED: To prevent the lowering of the effective value of a magnetomotive force and also to reduce torque ripple at the rotation of a rotor by adopting a concentrated winding method as a stator winding method. SOLUTION: In a synchronous reluctance motor where the magnetic resistance of a rotor, as seen from the side of a stator varies by the rotational position of the rotor, the stator has a plurality of teeth and a multiphase AC winding where only a winding for one phase is wound in a slot between the teeth, and the rotor is equipped with a plurality of pairs of magnetic paths forming magnetic poles between each other, and the pair of magnetic paths composed of a plurality of thin divided magnetic paths, and they are arranged so that positions of the divided magnetic paths in each pair of magnetic paths locate at unequal intervals with respect to the circumferential direction of the rotor.
