Abstract

PURPOSE: To make an increase of starting torque, with an angle enlarged between a stationary position of rotor pole and a position of stator pole, by means of changing a position of displacement pole of the stator poles 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 with one end of at least its pair of poles 6a, 6c displaced by L from center of stator reference poles 2b, 2d, 6b and 6d, with another end made facing to poles 2a, 2c. In this way, at no excitation, N.S poles of the rotor 3 will be standing still being displaced by an angle of θ1 from center of the stator reference pole by an attractional force of the displacement poles 6a, 6c. 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
