Abstract: In order to determine the influence of electromagnetic parameter design on the holding torque of hybrid
stepper motor, the influencing factors and the influencing strength were analyzed. Maxwell 3D finite element method was
used to model and simulate the motor under static magnetic field and calculate the holding torque characteristic curve of the
motor under different electromagnetic parameters. By comparing the simulation results, the optimal performance solution of
the motor under each parameter was obtained. The single variable method was used to verify the maximum influencing
factor. The experimental results showed that the law obtained in this study had certain reference value for structure design of
the stepper motor.
