Some basic knowledge of Servo Motor:

   An engine in a Servo system that controls the movement of mechanical components. In an automatic control system, used as an actuator to convert received electrical signals into angular displacement or angular velocity outputs on the shaft of an electric motor.

   Servo motor is divided into DC and AC servo motor, the main feature is that when the signal voltage is zero, no rotation phenomenon, speed with the increase of Torque and uniform decline, Servo Motor, can make control speed, the position accuracy is very good.

DC servo motor is divided into brush and brushless motor. Brush Motor has the advantages of low cost, simple structure, large starting             Torque, wide speed regulation range, easy control and maintenance. Brushless motor small size, light weight, high output, fast response, high speed, small inertia, smooth rotation, torque stability. The control is complex, easy to be intelligent, and the electronic commutation is flexible, which can be square wave commutation or sine wave commutation. Motor maintenance-free, high efficiency, low operating temperature, electromagnetic radiation is very small, long life, can be used in a variety of environments.

   AC servo motor is also brushless motor, divided into synchronous and Asynchronous Motor, current movement control are generally used synchronous motor, its power range is large, can achieve a great power. LARGE INERTIA, low maximum rotation speed, and with the increase of power and rapid decline. Therefore, it is suitable for low-speed smooth operation of the application.
