Abstract
PURPOSE:To reduce the size of the stepping motor by providing the same number of the magnetic poles of a stator as that of the excitation phases and providing specific position relation at the disposition of a plurality of teeth formed on the inner peripheral surface of the poles. CONSTITUTION:Cylindrical iron cores A, B cut with teeth at the same pitch interval on the outer periphery are secured to the outer peripheries of the north and south poles of a permanent magnet 2 to thereby form a rotor, and are confronted through small air gap on the inner peripheral surface of the magnetic pole 1 of the stator having a coil 5. A stator 1 having four magnetic poles. When a plurality of teeth formed on the inner peripheral surface of the magnetic pole exhibits an incremental angle by theta, the teeth group of the second pole is selected at the position of (90-theta) deg. at the center line, the third pole is selected at the position of (180-2theta) deg., and the fourth pole is selected at the position of (270+theta) deg. with the center line of the teeth group of the first magnetic pole as a refrence. Accordingly, the incremental angle can be retained as the conventional manner, and the number of poles can be reduced from 8 to 4, and further the motor can be reduced in size.
