The role of servo motors: Servo motors play an important role in the composition of automation equipment. The servo motor can convert the voltage signal into torque and speed to drive the control object, can control the speed, and the position accuracy is very accurate. The rotor speed of the motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an executive element, and has the characteristics of small electromechanical time constant, high linearity, and starting voltage, which can convert the received electrical signal. into the angular displacement or angular velocity output on the motor shaft.
