. Change the order in which the windings are energized and the motor will reverse. Therefore, it is possible to control the rotation of the stepper motor by controlling the number of pulses, frequency and power order of each phase windings of the motor. Each pulse signal corresponds to the power state of a phase or two-phase winding of a stepping motor, and the corresponding rotor turns over a certain angle (a step angle).
