とを特徴とするステツプモータ。[Claims for Utility Model Registration] Two stator plates are provided with a plurality of salient poles each having teeth formed at a constant pitch at their tips, and these stator plates are stacked with a permanent magnet sandwiched between the salient poles. In a step motor, the stator is configured by the permanent magnets, and the stator plate generates a bias magnetic flux from the permanent magnets and a magnetic flux from the coils wound around the stacked salient poles to generate rotating torque between the stator and the permanent magnets. 1. A step motor comprising magnetic flux leak prevention means that is in contact with the salient pole and extends between the teeth of the salient pole to make the polarity between the teeth the same as the polarity of the salient pole where the teeth are located.
