What is a servo motor?

- Feb 05, 2019-

Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and it is a kind of indirect transmission device of subsidized motor. Servo motor can make the control speed, position accuracy is very accurate, can convert the voltage signal into torque and speed to drive the control object. Servo motor rotor speed is controlled by input signal, and can react quickly, in the automatic control system, used as an executive element, and has the characteristics of small electromechanical time constant, high linearity, starting voltage and so on, can convert the received electrical signal into the motor shaft of the angular displacement or angular velocity output. Divided into DC and AC servo motor two categories, its main feature is that when the signal voltage is zero rotation phenomenon, the speed with the increase of torque and the uniform decline.
