This paper presents the method of modeling and numerical simulation of a hybrid stepper motor. The problem is solved by the electromagnetic field modeling, using the time-stepping finite element method. Circuit equations are coupled with field equations creating one global system of non-symmetric equations. The mechanical motion of the rotor is determined by solving the second order differential motion equation. The magnetic torque is calculated by the Maxwell stress tensor. The paper shows how motor load modifications influence the response dynamic and torque ripples in the electromagnetic torque characteristic. It is shown that the FEM stepper model including the analysis of inertia controlled system can be used as support for improving tool and technics designed as predicting and controlling the electromagnetic torque ripples for motor drive applications. The simulations’ results of electromagnetic torque are verified and compared with the results obtained from laboratory kit using FAST (ang. Force Angle Speed Torque) technology sensor.
