The servo motor is also known as the executive motor. In an automatic control system, it is used as an execution element to convert the received electrical signal into an angular displacement or angular speed output
on the motor shaft.
The servo motor can control the speed, the position accuracy is very accurate, can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can react quickly. In the automatic control system, it is used as an execution element, and has the characteristics of small electromechanical time constant and high linearity, so the received electrical signal can be converted into the angular displacement or angular speed output on the motor shaft.
Advantages:
Compared to the traditional motors, the servo motors are more integrated, and they can use a smaller volume to achieve more complete functions. This not only provides ample room for the device to expand other functions, but also provides higher possibilities for the device to really be done as small and refined.
