1. Accuracy: realizes closed-loop control of position, speed and torque; overcomes the problem of stepping motor out of step;

2, the speed: high-speed performance is good, the general rated speed can reach 2000 ~ 3000 rpm;

3. Adaptability: It has strong anti-overload capability and can withstand three times the rated torque. It is especially suitable for occasions with transient load fluctuations and quick start.

4. Stable: It runs smoothly at low speed, and does not produce stepping operation similar to stepper motor when running at low speed. Suitable for occasions with high speed response requirements;

5. Timeliness: The dynamics of motor acceleration and deceleration are short, generally within tens of milliseconds;

6, comfort: heat and noise are significantly reduced.

To put it simply: the ordinary motor that you usually see, after power off, it will turn for another moment because of its own inertia, and then stop. The servo motor and the stepper motor stop and stop, and walk away, the reaction is extremely fast. However, stepper motors have lost synchronization.

There are too many applications for servo motors. As long as there is a power source, and the accuracy requirements are generally involved in the servo motor. Such as machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robots, automated production lines, etc., which require relatively high requirements on process accuracy, processing efficiency and operational reliability.

The servo motor is used inside a closed loop. That is to say, it transmits the signal to the system at any time, and at the same time, the signal given by the system is used to correct its operation.

The servo motor can also be controlled by a single chip microcomputer.
