The stepper motor, power supply, and load mechanism comprise an electric drive where the moving part executes discrete step movements following voltage pulses generated by the control system. It's essentially an electric drive with angular position control, where each voltage impulse corresponds to a change in the rotor's position. Unlike other motors, stepper motors don't require feedback signals to determine rotor angular displacement, offering a significant advantage. This paper focuses on open-loop control for stepper motor control, emphasizing the preparation of suitable synchronous phase voltages to manage rotor angular displacement. The study includes modeling in the Matlab/Simulink environment and experimental implementation of a hybrid stepper motor position control system, confirming stepping behavior through both simulation and experimentation. The control algorithm utilizes an Arduino processor, while a PWM driver A4988 is employed to supply the hybrid stepper motor winding coils in the experimental setup. Furthermore, the ability to control the direction of rotation of the stepper motor is demonstrated. The simulation results align closely with experimental findings.
