Advantages of closed-loop stepper motors
The performance of a closed-loop driven stepper motor is superior to an open-loop driven stepper motor in all respects. The stepping motor closed-loop drive has the advantages of stepping motor open-loop drive and DC brushless servo motor. Therefore, in a position control system with high reliability requirements, a closed-loop controlled stepping motor will be widely used.
What is the difference between open-loop and closed-loop of stepper motor?
1. Open loop control content allows the other party to execute. No feedback. Closed loop control requires the other party to execute and report it to you. Have feedback.
2. Whether it works for the current control. Open-loop control is generally a control activity that is completed in an instant, and closed-loop control must last for a certain period of time, which can be judged by this.
If you want to buy a power tool motor, please pay attention to antenna dc motor.
