摘要：
There is provided a self-starting permanent magnet synchronous motor in which a center axis of magnetic poles of a rotor is assumed to be a d axis, an axis deviated from the magnetic pole center axis by an electric angle of 90 degrees is assumed to be a q axis, at least two or more starting bars which are arranged near the d axis are arranged on a bore side of the bars near the q axis and are arranged in parallel with the q axis, so that a stable starting torque can be generated irrespective of a generating position of a stator magnetic flux which changes due to applying timing of a power source and a phase of a voltage, and a vibration/noises at the time of a stationary operation can be reduced.
