Machine with the development trend of frequency converter performance for: one is the high performance. At present basically all inverter require vector way to master, and there is a small amount of different levels of mastery of the structure and the algorithm. It is worth noting speed sensorless vector master (SVC) are developing rapidly in recent years, due to SVC may require low interest rates, high function of disposal plan, had become general converter dream norms and developing direction. 2 it is easy to master sex enhances unceasingly. Users in frequency converter demand change to the field devices and the software by adding a set of tools to through user operations so as to simplify debugging process. Three is function modular and intelligent demand to rise gradually.

To understand that a machine tool need of inverter quantity some can reach 4 ~ 5 sets. It is enough to foresee machine converter market potential. At present our country machine with frequency converter most Japanese market brand, such as mitsubishi inverter is as close to the server functions, so the application in machine or more, Because of its functions and Taiwan amounted to nearly mitsubishi, but the price cheap many, cost-effective, in recent years market share will increase gradually.

In the lathe products, inverter application scope most. However, Japans AnChuan, Fuji, mitsubishi and Taiwan platform of the brand such as have a large share of the market. Despite a few homebred brand by machine manufacture enterprise adopts inverter, such as shenzhen HuiChuan inverter in lathe applications having a good game, but in the grinder, such as metalforming machine in frequency converter function of products to demand higher in the field, is still foreign brand is in the majority, such as mitsubishi, Fuji, Siemens Germany and Taiwan reaches the brand such as still edge.

According to in 2008, 2009 machine sales data display, general-purpose machine especially function various lathes inventory status quite stark and compound machine tools, large heavy product market is good. These machining range, machine parts with different activity implementation of inverter speed, function also put forward higher request, home-made frequency converter manufacturers more should seize the opportunity, no-till plant machine market.
