摘要：
A permanent magnet synchronous motor includes a rotor having cage windings and permanent magnets placed on an inner peripheral side of these cage winding bars, where the permanent magnets are placed and polarized so that a ratio θ/α between a circumferential pitch angle θ of magnetic flux distribution of the permanent magnets and a magnet pole pitch angle α is between 0.67 and 0.91.
