STEPPING MOTOR

摘要

Provided is a stepping motor which can obtain a large torque without increasing the external diameter.  More specifically, the stepping motor (100) includes a plurality of stator sets (20) which are arranged in the direction of the motor axis line L, so that electrode teeth (215, 225, 265, 275) have an identical angle position between the stator sets (20).  In a rotor (3), a rotor magnet (32) is formed by a plurality of magnet pieces (320) which are arranged in the direction of the motor axis line L.  In the rotor magnet (32), the same magnetic pole is continuously formed over the entire motor axis line L direction.
