(Summary description)When the stepping motor rotates, the inductance of each phase winding of the motor will form a reverse electromotive force; the higher the frequency is, the greater the reverse electromotive force is. Under its action, the phase current of the motor decreases with the increase of frequency (or speed), resulting in the decrease of torque.
