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 nput 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.
The motor has the advantages of good low voltage characteristics, strong torque overload characteristics, large starting torque (rotation blocking characteristics), and small starting current.
In addition, the servo motor is widely used in the computer embroidery machine and other textile machinery and equipment.
