The Trend of Inverters for Machine Tools Is Reflected

One is high performance. At present, basically all inverters require vector mastering, and a small number of different levels of mastering structure and algorithms have emerged. It is worth noting that speedless sensor vector mastering (SVC) is developing rapidly in recent years, because SVC can require low interest, high-function disposal plan, has become the dream specification and development direction in the universal inverter.

Second, easy to master the continuous improvement. The user's demand for inverters has gradually shifted to a field unit and setup tools have been added to the software to simplify the commissioning process through user operation. Third, the demand for functional modularity and intelligence is gradually increasing.

It is understood that a machine tool needs to use the number of inverters up to 4-5 units. This is sufficient to anticipate the market potential of machine tool drives. At present, most of the inverters used in China's machine tool market are Japanese brands, such as Mitsubishi inverters due to close to the function of the server, so the use of machine tools is also more, and domestic inverters because of its function close to Mitsubishi, but the price is much cheaper, cost-effective, in recent years the market share has gradually increased.

According to the sales data of machine tools in 2008 and 2009, the inventory situation of general-purpose machine tools, especially the multi-functional lathes, is quite severe, while the market for composite machine tools and large heavy-duty products is better. These machine tools have a wide range of processing, machine tool implementation components have different speed of activity, the inverter function also put forward higher requirements, domestic inverter manufacturers should seize the opportunity to cultivate the machine tool market.
