Industry Information
Market space of inverter in machine tool industry
2011-5-22 17:29:23

The number of inverters required for one machine tool can reach 4-5. This is enough to foresee the market potential of machine tool inverters. At present, most of the inverters used in China's machine tool market are Japanese brands. For example, Mitsubishi inverters are used in machine tools because they are close to the functions of servos. Delta's functions are close to Mitsubishi, but the price is much cheaper and cost-effective High, market share has gradually increased in recent years.

At present, the development trend of frequency converters for machine tools is as follows: First, high performance. At present, basically all inverters require vector control methods, and a few different levels of control structures and algorithms have appeared. It is worth noting that the speed sensorless vector control (SVC) has been developing rapidly in recent years. Because SVC can require low interest and high power disposal plans, it has become the dream specification and development direction in general inverters. Secondly, the ease of mastery has been continuously improved. The user's requirements for the inverter are gradually transformed into field devices, and setting tools are added to the software in order to simplify the debugging process through user operations. Third, the demand for functional modularization and intelligence has gradually increased.

In lathe products, the application range of inverter is the most. However, brands such as Japan's Yaskawa, Fuji, Mitsubishi, and Taiwan's Delta have a large market share. Although there are also some domestic brand inverters used by machine tool manufacturers, such as Shenzhen Huichuan inverters which perform well in lathe applications, but in fields such as grinders and forging machine tools that have higher requirements for the function of inverter products, they are still abroad. Most brands, such as Mitsubishi, Fuji, Germany's Siemens, Delta and other brands are still in an advantage.
