First of all, we look at the servo motor and other (e.g., stepper motor) compared to what's advantages:

Realized the position: 1, precision, speed and torque of the closed loop control; Overcome the problem of step motor out of step;

2, rotational speed, high speed performance is good, generally rated speed can reach 2000 ~ 2000 RPM;

3, adaptability, resistance to overload ability is strong, can bear the load of three times the rated torque, rapid start to have instant load fluctuation and requirement of special applicable occasions;

4, stability, low speed running smoothly, won't produce similar to the stepper motor during low speed running step run phenomenon. Suitable for high speed response to the requirements of the occasion;

5, timeliness: motor deceleration dynamic response time is short, usually within a few milliseconds;

6, comfort: fever and noise is decreased obviously.

Simple say is: common to see the kind of ordinary motor, it will be when the power is turn again because of their inertia for a while, and then stop. And servo motor and stepper motor is say stop, said go walk, fast reaction. But stepping motor out-of-step phenomenon exists.

The application areas of servo motor is too much. As long as it is to have power, and the requirements for accuracy is generally may involve the servo motor. Such as machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robot, automatic production line of process precision, such as relatively high processing efficiency and working reliability requirements of the equipment.
