Abstract
PURPOSE: To obtain a motor of low power consumption, by making the magnetization of at least one set of facing poles of the stator in a reverse direction.
CONSTITUTION: The motor is constructed by, for instance, a rotor 201 of permant magnet having four magnetic poles, a stator 202 to 204 having a protruding part 206 209 of minimum magnetic resistance point (statically stabilized point) in its inner circumference, and a drive coil 205. With a drive pulse ϕ1 applied to the drive coil 205, an energization is made of the stator 202 to N-pole and the stator 203 to S- pole, simultaneously, magnetic fluxes come to be in a direction from the stator 202 to the stator 204 at around the position of a pole 210 and in a direction from the stator 204 to the stator 203 at around the position of a pole 211, consequently, the rotor 201 is given a torque in a clockwise direction, being rotated 90 deg of angle and reaching the next statically stabilized point to cease its motion. Subsequently, with the drive pulse ϕ1 applied, the rotor is further rotated 90 deg of angle with its motion ceased, and the same condition is restored as the initial position of the pole.
