In this article is reviewed the mathematical model of the stepper motor. Analysis of mathematical models showed the presence of oscillation the impulse response, thereby requiring backup duration of the control pulse. The work provides an example the realization of algorithm for calculating a minimum time for one cycle of operation of stepper motor. The results of these studies can be used in the stepper motor control system to increase speed and reduce power consumption associated with the stepper motor control.
