PROBLEM TO BE SOLVED: To obtain a permanent magnet type synchronous motor capable of generating high torque and facilitating the wiring work of a wire. SOLUTION: The permanent magnet type synchronous motor comprises a rotor having a plurality of permanent magnets arranged in the circumferential direction, a stator core having a plurality of salient magnetic poles arranged so as to oppose the permanent magnets, a plurality of windings wound around the salient magnetic poles, and a control device for passing an AC current to the windings in accordance with moving positions of the permanent magnets. The control device passes to the windings the AC current which has the same number of phases as that of kinds of phases corresponding to positional relations between magnetic poles of the permanent magnets and magnetic poles of the salient magnetic poles.
