Abstract
PURPOSE:To smoothly start a motor, by stopping a rotor exactly at a specified position where boundary sections between poles N and poles S are always confronted with the width-directional central section of exciting coils. CONSTITUTION:A rotor main-unit 22 is magnetized uniformly at 12 magnetic poles, and between the center lines of adjacent exciting coils among exciting coils C1-C4, every three magnetic poles are positioned. An angle alpha formed with lines for connecting both the side ends of the respective magnetic poles to a rotor central-point coincides with an angle beta formed with lines for connecting both the side ends of the exciting coils C1-C4 to the rotor central- point. When a rotor is turned into a stop space, then a magnetic path as shown in an arrow head against the field core of the respective exciting coils C1-C4 by the respective magnetic poles of the rotor main-unit 22 is formed. Accordingly, the rotor 22 is stopped at a position where the boundary sections of the magnetic poles are positioned at the central sections of the respective exciting coils C1-C4.
