Performance comparison between servo motor and stepping motor

As an open-loop control system, stepping motor has essential connection with modern digital control technology. In the current domestic digital control system, stepping motor is widely used. With the emergence of all digital AC servo system, AC servo motor is more and more used in digital control system. In order to adapt to the development trend of digital control, stepping motor or full digital AC servo motor is mostly used as the executive motor in motion control system. Although they are similar in control mode (pulse train and direction signal), they are quite different in performance and application. This paper compares the performance of the two.

What is the reason why the freezer is not cooling

It may be that the capillary is blocked and the refrigerant flow does not enter the evaporator. It may also be that the refrigerant needs to be replenished or the refrigeration system is leaking. If the buffer tube inside the compressor ruptures, there may be loose screws or it will cause no cooling. It is also possible that the expansion valve and the discharge valve are not adjusted properly, causing cold air to leak out. Need to check one by one, and then take the medicine.

11 common problems with refrigeration compressors, do you know these?

Impurities entering the friction surface of the moving parts of the compressor pump body will cause abnormal scratches and wear. Impurities entering the solenoid valve, expansion valve, control valve, capillary tube and stop valve in the refrigerator system will block the valve hole or make the valve close tightly. And fail.
