PROBLEM TO BE SOLVED: To provide a rotor support structure of a slim step motor for supporting a rotary shaft by only one bearing.SOLUTION: The slim step motor includes a rotor comprising a magnet support provided on the peripheral face of a rotary shaft and a magnet provided on the peripheral face of the magnet support, and stators disposed at regular intervals on the peripheral face of the magnet. The structure for supporting the rotor is provided. The stator is formed of a stator case, a yoke, a rotary shaft bearing, and a terminal part, which are integrally injection-molded. The rotor comprises the magnet support fitted and fixed on the rotary shaft, and the magnet provided on the peripheral face of the magnet support. The rotary shaft is inserted in the inner diameter part of the rotary shaft bearing and rotatably supported by the rotary shaft bearing. |
