In recent years, due to China's positive and stable monetary policy, the investment in fixed assets has been increased, and the transportation, construction, machinery, national defense and other industries have been supported by *, which has driven the reducer industry to maintain a good growth rate. Reducer machinery manufacturing industry belongs to the basic equipment industry of national economy, and its development is closely related to national macro-economy for a long time. With the improvement of the industrial production level, management mode, marketing mode, product output and export delivery value of the reducer industry in recent years, the balanced cooperation of the industrial chain has also been driven correspondingly, making the reducer industry gradually integrate into the chain of the high-end industrial chain and become the pioneer industry of independent innovation.
At present, most of the frequency converters used in China's machine tool market are Japanese brands. For example, Mitsubishi inverter is widely used in machine tools because it is close to the function of server; while Delta, because its function is close to Mitsubishi, is much cheaper and cost-effective, and its market share has gradually increased in recent years. In lathe products, the application range of frequency converter is more. However, Japanese brands such as Yaskawa, Fuji, Mitsubishi and Taiwan's Delta have a large market share. Although some domestic brand frequency converters are adopted by machine tool manufacturers, such as Shenzhen Huichuan inverter, which performs well in lathe application, foreign brands still dominate in the fields with high functional requirements for frequency converter products, such as Mitsubishi, Fuji, German Siemens, Delta, etc. According to the sales data of machine tools in 2008 and 2009, the inventory situation of general-purpose machine tools, especially those with various functions, is quite severe, while the market of composite machine tools and large-scale heavy-duty products is better. These machine tools have a wide range of processing, and the parts of machine tools have different moving speeds, which also put forward higher requirements for the function of frequency converter. Domestic inverter manufacturers should seize the opportunity to cultivate the machine tool market.
"UNF climate change project climate communication - China series of activities" was held in Beijing from April 2 to 4, 2014. The activity disseminated the research results of the second working group of the IPCC fifth assessment report, and on this basis, it discussed the situation of climate change in China and the measures to deal with climate change. Zheng Tan, director of China District of Switzerland TOP10 energy conservation center, introduced the energy efficiency of motor system at the enterprise forum. The power consumption of electric motors is very large. However, the government has been subsidizing motor manufacturers, and the power consumption is mainly generated by motor users. The energy efficiency of the system can not be improved by simply replacing the high efficiency motor. Our country has replaced a considerable number of high-efficiency motors through the energy-saving products benefiting the people project and the road map for eliminating backward motors in the national motor energy efficiency improvement plan. However, the energy-saving potential brought by the replacement of high-efficiency motors is limited, and the efficiency of the motor system is still 10-20 percentage points lower than that in the world.
