Abstract

PURPOSE:To increase the response power to a load and to enhance the cooling effect, by forming a plane having an approximately true circle shape, which faces a rotor core of a pole part, providing magnetic resistance holes on both sides of the pole center part, and bringing the magnetic flux distribution of the magnetic poles closer to a sine wave. CONSTITUTION:The magnetic pole parts 3 are extended to the right and left of a yoke part 2 to which a coil is provided. The tips of both magnetic poles 3 are linked by a bridge part 4. Furthermore, the part 6 of the inner diameter of a stator core facing the rotor core 9 with a gap 11 being provided is formed in a shape of an approximately true circle, except for the bridging part 4 and a shading coil winding part 8. At a suitable part on the both sides of the center of magnetic pole, are provided one or plurality of the magnetic resistance holes 12. In this constitution, since the magnetic flux distribution in the gap 11 is brought closer to the sine wave, the trough in a torque curve becomes small. Since the magnetic resistance holes 12 also serve as ventilating holes, the cooling effect is enhanced.
