Tips: Why the torque of the stepper motor is reduced along with the rise in rotational velocity?
When the stepper motor rotates, the inductance of each phase winding of motor will form a reverse electromotive force. The higher the frequency the larger the reverse electromotive force. Under its role, the the phase current of motor is reduced along with the increase in frequency rate (or velocity), thus the torque decreases.
