Abstract: Stepper motor is one of the key equipments for the stable operation of the power system. When the stepper motor breaks down during the operation, it will directly lead to the shutdown of the power system and bring economic losses to the power enterprises. It is necessary to study the causes of the internal faults of the stepper motor. The changes of current field and magnetic field caused by out-of-step fault and open-circuit fault of stepper motor were studied by means of COMSOL finite element analysis and modeling, and the changes of current field and magnetic field caused by out-of-step fault and open-circuit fault under five different frequencies were analyzed to improve the efficiency of fault diagnosis of stepper motor.

Key words: stepper motor, out-of-step fault, open-circuit fault, electric field change, magnetic field change
