ングモータ。An inner stator yoke with many pole teeth on its outer circumferential surface, an outer stator yoke with the same number of pole teeth on its inner circumferential surface as the inner stator yoke, and a cylinder with multi-pole magnetization on its inner and outer circumferential surfaces. In a stepping motor in which a magnet rotor is arranged concentrically with respect to a rotor shaft, the pole teeth of the inner stator yoke and the pole teeth of the outer stator yoke are arranged so as to face each other on a radial line centered on the shaft. A stepping motor characterized in that the cylindrical magnet rotor is magnetized so that the phase of the magnetic poles is shifted by 1/2 pole pitch between the inner circumferential side and the outer circumferential side.
