Servo motor is an engine that controls the operation of the mechanical elements in the servo system. It can control the speed and convert the voltage signal into the torque and rotational speed to drive the control object.
The servo motor is maintenance-free, with high efficiency, low operating temperature, small electromagnetic radiation, long life, and can be used in various environments. The disadvantage of brushless servo motors is that they are high price and easy to lose effect in high magnetic field environment.
The servo drive system of open winding motor has the advantages of multi-level voltage output ability, reducing switching loss and certain fault tolerance ability, and the application of industrial servo control in domestic colleges and universities is increasing. The switching power supply adopts voltage conversion and power grid isolation, which compared with the traditional DC voltage stabilizing power supply has the advantages of high efficiency, high stability and small size.
