A stepping motor is a motor that converts electrical pulse signals into corresponding angular or linear displacements.Every time a pulse signal is input, the rotor rotates an angle or advances one step, the output angular displacement or linear displacement is proportional to the number of input pul

The stator winding of the motor is the part that generates the rotating magnetic field, and its failure will directly affect the normal operation of the motor. Common faults of stator windings are as follows:1. MoistureIn the motor storage location or workplace, if the humidity is high, the motor ma
