Abstract
PURPOSE: To prevent unsteady revolution or cogging of a flat type motor by corrugating a stator yoke to which concentrated windings are applied opposite to a permanent magnet rotor.
CONSTITUTION: A rotor 1 having a plural N/S pole for which a magnetic flux distribution is made rectangular is provided rotatively, and a stator yoke 2 comprising an upper part 21 and a lower part 22 is provided to surround the rotor 1. Then, the upper part 21 and the lower part 22 are corrugated alternately each other, a corrugated main pole 23 and auxiliary pole 24 are formed respectively on the upper part 21 and the lower part 22, and a concentrated main winding 25 and a concentrated auxiliary winding 26 are applied respectively to the main pole 23 and the auxiliary pole 24. By arranging such, a gap between the main pole 23 and the rotor 1 and that between the auxiliary pole 24 and the rotor 1 are minimized at the center of the magnetic pole but maximized at both ends, thus giving a sine wave distribution to prevent unsteady revolution or cogging of the motor.
