Stepper motor can not directly use ordinary AC/DC power supply at high speed. It needs special servo controller. Pay attention to the following characteristics:
1. The digital signal can be directly used for open-loop control. The whole system is simple and cheap. The displacement corresponds to the number of input pulse signals. The step error does not accumulate for a long time. The open-loop control system is simple and has certain accuracy. A closed loop control system can also be used.
2. Since the stepping motor has no brush, the body parts are few and the reliability is high.
3, easy to start, stop, forward and reverse, speed response is good; generally have self-locking ability when stopping.
4, the step angle can be selected in a wide range, in the case of small step, it can run stably at high torque at ultra-low speed, and can directly drive the load without the reducer.
5, the speed can be smoothly adjusted in a relatively wide range, you can use a controller to simultaneously control several stepper motors to run synchronously.
6. The stepping motor has poor inertial load capability. Due to the out-of-step and resonance problems, the stepping motor's acceleration and deceleration method is more complicated under different application conditions.
