The machine has winding system which is provided in slots of laminated core of stator. The grooves have an air gap point formed between stator and rotor (1). The coercive force of permanent magnets starting from the center portion of the pole (2) to the ends (3) of the pole is increased, while radial height (5) and the remanence of the permanent magnets starting from the center of pole to the ends of the respective pole viewed in the circumferential direction is decreased. |
