The speed of the stepper motor is related to the size of the load:
1. The current of the stepper motor is related to the load, and the size of the current determines the size of the torque.
2. As long as the load torque is not greater than the holding torque of the stepper motor, its speed and load are not related, at this time, the speed of the stepper motor is determined by the pulse frequency, the higher the frequency, the higher the speed.
3. If the load torque is too large, the motor does not move the load, and there is a serious step loss, then the speed of the motor is related to the load.
