Principle and characteristics of servo motor
Servo motor is a kind of motor which uses the principle of electromagnet to convert pulse signal into linear displacement or angular displacement. With each electric pulse, the motor rotates at a certain angle to drive the machine to move for a short distance.
Features of servo motor:
(1) Take a pulse, turn a step angle.
(2) Controlling pulse frequency can control motor speed.
(3) The rotation direction can be changed by changing the pulse sequence.
As the function of servo motor is just in line with the requirements of digital control system, it is widely used in CNC machine tools, watch industry and automatic recorder.
