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 are the characteristics of air compressor lubricants

In addition to reducing the friction, wear and temperature rise of the motion pair, air compressor lubricants. It also has the function of sealing compressed air. The lubricating oil of the air compressor directly contacts the compressed gas of high temperature and high pressure, so it is easy to cause lubrication failures that are not found in other machinery.

Application of synthetic compressor oil

At present, synthetic lubricants are widely used in the compressor field. Among them, oil-injected and oil-immersed rotary screw air compressors and large reciprocating compressors are one of the most used markets. For example, the sales volume of synthetic compressor oil in Western Europe was 6000t in the late 1980s, and it rose to 10000 in the early 1990s. The sales volume in the United States has exceeded 15,000 tons, and it is increasing at a rate of more than 10% per year.
