摘要：A stepper motor device has a stator and a rotor. The rotor comprises: a shaft; arotor core associated with the shaft; and a magnet fixed to the rotor core. The statorcomprises: a stator shell; a yoke disposed within the shell; a coil wound about the yokeand an end plate magnetically connecting the yoke to the stator shell. The coil is located
beside the magnet in the axial direction of the motor. The stator has a number of salientpoles, and the salient poles are arranged to face the magnet across a small air gap. Thecoil creates magnetic poles in the salient poles with a common polarity.
