nema 23 two-phase long stepper motor

- Jan 26, 2018 -

                                   The starting frequency characteristic of stepper motor can not reach the running frequency directly when the stepper motor starts, but it should have a starting process, that is, from a low rotational speed to the running speed. The frequency of the stop operation cannot be reduced immediately to zero, and there is a process of decreasing speed to zero. The output torque of stepper motor decreases with the increase of pulse frequency, the higher the starting frequency, the smaller the starting torque, the less ability to drive the load, the lower the start-up time, and the overshoot when the stop occurs.
