Servo motor refers to the engine that controls the operation of mechanical components in the servo system, which is a subsidy motor indirect speed change device. The servo motor can control the speed, the position accuracy is very accurate, and can convert the voltage signal into the torque and rotation speed to drive the control object.
Servo motor is divided into DC servo motor and AC servo motor. The DC servo motor is divided into brushless motor and brush motor, and the AC servo motor is brushless motor, so it is divided into synchronous motor and asynchronous motor.
Advantages: accurate speed control, torque speed characteristics are very hard, simple control principle, easy to use, cheap price.
It is widely used in ATM machine, inkjet drawing equipment, lettering machine, photo machine, medical instruments and equipment, industrial control system, robot and other fields.
