Stepper motor running speed is not enough to do? How to increase the speed of stepper motor?

At present, the use of stepper motors is still very widespread, although some performance can not catch up with the servo motor, but in many areas is sufficient, and cheaper.

Stepper motor in the actual operation, sometimes there is not enough speed, which is mainly due to what causes it? How to improve the speed of the stepper motor?

1. if the actual speed is slower than the theoretical speed, it is likely that the stepper motor is out of step or the load is large.

2. If the theoretical speed is slower, it means that the pulse frequency is relatively low, and changing the pulse frequency can improve the speed.

How to improve the speed of the stepper motor? The following methods are recommended.

1. Increase the pulse frequency. As an example, if the pulse frequency is increased to 100KHz, the speed is equal to 50rpm, which is a tenfold increase in speed. If you use PLC pulse output to control stepper motor, then the PLC pulse output frequency of what is, some PLC can support 20KHz, 200KHz and 500KHz high-speed pulse output, so you can provide faster speed.

2. Reduce the subdivision factor m, for example, reduce m to 5, the speed is equal to 10rpm.

Note that the stepper motor when the pulse frequency can be increased, try not to reduce the value of m; then again, the speed of the stepper motor should not exceed 600rpm.

Stepper motor running speed is not enough to do? How to improve the speed of the stepper motor? The above has been briefly answered, I believe it will help you!
