備えたステツプモータ。 A stator that has a rotor that has a permanent magnet with a large number of magnetic poles magnetized in the circumferential direction, a stator core that has magnetic pole teeth on opposing surfaces facing both sides of the permanent magnet in the axial direction of the rotor, and a coil that excites the stator core. and a sensor magnet provided on the rotor and arranged in parallel in the axial direction of the stator core, and a sensor magnet provided on the stator on the opposite side of the sensor magnet to the stator core to detect the magnetic flux of the sensor magnet. A step motor comprising: a sensor; and a magnetic plate placed on the stator core side of the sensor magnet to shield the stator core from magnetism.
