テツプモーター用ローター。 A rotor for a step motor consists of a cylindrical rotor magnet having a central shaft hole and multipole magnetized on the outer peripheral surface, and a rotor shaft that penetrates the central shaft hole of the rotor magnet and serves as the central axis of rotation. , the rotor shaft is comprised of two parts, a large diameter part and a small diameter part, with different outer diameters, and the rotor magnet is pivotally attached to the small diameter part of the rotor shaft so as to be in contact with the large diameter part of the rotor shaft. Features a rotor for step motors.
