Abstract

Provided is a stepper motor. The stepper motor includes a rotor shaft, a steel magnet sleeved and fixed to an outer peripheral side of the rotor shaft, a winding unit sleeved to the rotor shaft, and two flexible circuit boards fixed to the winding unit. The winding unit includes two windings. Each winding includes a housing sleeved to and rotationally connected to the rotor shaft, two skeletons fixed to an inner peripheral side of the housing and coaxially disposed with the housing, and coils, where a respective coil is fixed to a respective skeleton. In the stepper motor of the present disclosure, the number of windings in the assembly of the whole machine can be reduced, making the process simpler, reducing the deviation of concentricity after assembly, and also making it possible to avoid the risk of damage to the whole machine caused by the abnormality of the single coil.
