PURPOSE:To always obtain a high torque, by organizing an armature in the range of one angle among the equally divided angles of the center angle at 360 deg. on the full periphery, to be conducted only by the given current of one phase. CONSTITUTION:On the outer periphery of a stator 1, a rotor 2 provided with magnetic poles on the inner peripheral surface is rotatably set. In the meantime, on the outer peripheral section of the stator 1, nine cores 4 organizing armatures 6 are arranged. When the center angle is equally divided into three, then the armatures in the range of the center angle divided equally into three, 2pi/3 are of three pieces, but the cores 4 organizing each one set with the three pieces are wound up only with the coils 5 of each one phase so that the adjacent coils may be wound up in the mutually opposite directions. By this organization, to the armatures 6 of three pieces each, the always given current of one phase flows, and magnetic flux generated by the current of one phase is not offset with magnetic flux generated by the current of other phase, and thereby high torque is obtained.
