ータ。 A rotor having a magnetic pole part in which a large number of opposing magnetic poles are arranged alternately in the circumferential direction, a coil, and magnetic poles arranged on both sides of the magnetic pole part of the rotor to face the rotor magnetic pole part at a fixed interval, respectively. In the step motor, the opposing stator magnetic pole portions have opposite polarities due to excitation of the coil. A step motor characterized in that the rotor magnetic pole portions are provided on opposing surfaces of double cylindrical portions, and the rotor magnetic pole portion is provided on a cylindrical portion having a common axis and inserted between the double cylindrical portions.
