A servo motor is an engine that controls the operation of mechanical elements in a servo system, and is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy accurately, and can convert the voltage signal into torque and rotating speed to drive a control object. The rotation speed of the rotor of the servo motor is controlled by an input signal and can quickly respond, the servo motor is used as an actuating element in an automatic control system, has the characteristics of small electromechanical time constant, high linearity, starting voltage and the like, and can convert a received electric signal into angular displacement or angular speed on a motor shaft for output.
