<p>A stepping motor, characterized in that a soft magnetic intermediate magnetic body magnetically independent of stator yokes on both sides is disposed between two adjacent stator yokes at a specified position where the magnetic body is closely opposed to the magnetic pole passing surface of a permanent magnet, the magnetic body is formed by punching a ferromagnetic sheet metal and sagged faces formed by the punching are positioned on the opposite side of the permanent magnet, and a pinion is coaxially connected to a rotor and a specified positional relation is formed between the gear teeth of the pinion and the magnetic poles of the rotor.</p> |
