Servo Motor

A servo motor is an engine that controls the operation of mechanical elements in a servo system. It is an auxiliary motor indirect speed change device. ‌The main feature of a servo motor is that it can control speed and position accuracy very accurately, and can convert voltage signals into torque and speed to drive the control object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly. It is used as an actuator in an automatic control system and has the characteristics of small electromechanical time constant, high linearity, and starting voltage.
