1.Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is an auxiliary motor indirect transmission.
2.Definition: The rotor speed is controlled by the input signal and can react quickly. It is used as an executive element in the automatic control system, and has a small electromechanical time constant, high linearity. The servo motor can control the speed and position accuracy very accurately. The voltage signal is converted into torque and speed to drive the control object.
