Abstract
PURPOSE: To heighten a productivity and reliability, by providing a proportion, in a specific range, of pole width of the stator displacement pole with respect to that of the stator reference pole in a synchronous motor of inductor type.
CONSTITUTION: For a permanent magnet rotor 3, constructed with N.S poles in the peripheral part alternately and symmetrically magnetized, stator poles are arranged not symmetrically, when determined width of the stator reference poles 2b, 2d, 6b and 6d for L1, with width L2 of the stator displacement poles 2a, 2c being made in a range of L1 to 1.5L1, and with width L3 of the stator displacement poles 6a, 6c being similarly made in a range of L1/1.5 to L1. At no excitation, the pole of the rotor 3 will stand still being displaced by an angle of θ1 from center of the stator reference pole. When excited in the same polarity as each facing and neighboring pole of the rotor 3 by a current of half cycle at the time of power source closing, a force of repulsion between the rotor 3 and the stator 2, 6 will provide a rotation in C. W. direction R
