How frequency conversion technology realizes value in modern industrial enterprises


The core factor that variable frequency drives are widely used in modern industrial enterprises is the formation of drive control power electronics consisting of AC motor variable frequency drive, application of micro-industrial control computer control system, industrial operation information processing, signal feedback and sensor element alarm display. New Field. Therefore, the progress and development of modern motor-power electronic control integrated variable speed drive technology has become the most basic and important technical requirement of modern industrial enterprises.
With the development of modern AC drive technology, for high-voltage and high-power AC motors above 2000kW, the AC-AC variable frequency speed control system is superior to the DC motor drive system and has been widely used. Its demand continues to increase, and various types of machinery and equipment driven by modern industries show excellent operating performance characteristics of high efficiency, energy saving, safety and reliability.
The AC drive can not only achieve the necessary speed characteristics of the load machinery, but also improve the power and speed characteristics of the AC drive itself, so as to realize the load machinery or develop a complete set of equipment systems. At the same time, the load machinery and the drive motor will interact to achieve further rapid development.


According to the actual use of high-power general-purpose inverters in China, the average energy saving can reach 30%. Therefore, the investment and wide application of the variable frequency speed control system will make the economic effect of energy saving and consumption reduction self-evident.
