It refers to the engine that controls the operation of the mechanical components in the servo system.

    Main function: use in closed loop, pass signal to the system at any time, at the same time give the signal of the system to correct the operation.

    Advantages of servo motor and other motor (such as stepper motor) :

    1. Accuracy: realize the closed-loop control of position, speed and torque; The problem of stepping motor out of step is overcome.

    2. Speed: high speed performance, the general rated speed can reach 2000 ~ 3000 RPM.

    3. Adaptability: strong resistance to overload, able to withstand three times the load of rated torque, especially suitable for occasions with instantaneous load fluctuation and quick start.

    4. Stability: the low-speed operation is stable, while the low-speed operation will not produce the step operation phenomenon similar to stepping motor. Suitable for situations with high speed response requirements.

    5. Timeliness: the dynamic response time of motor acceleration and deceleration is short, usually within a few tens of milliseconds.

    6. Comfort: heat and noise are significantly reduced.
