The servo motor can control the speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. Servo motor rotor speed
Controlled by the input signal, and can react quickly, in the automatic control system, used as an executive component, and has the characteristics of small electromechanical time constant, high linearity, starting voltage, etc., can convert the received electrical signal into the angular displacement or angular speed output on the motor shaft.

What is a servo motor? How many types are there? What are the characteristics of the job?
A: The servo motor, also known as the execution motor, is used as an executive element in the automatic control system to convert the electrical signal received into the angular displacement or angular speed output on the motor shaft. It is divided into two categories of DC and AC motors, and its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases at a constant rate with the increase of torque.
