The current situation and Prospect of high and low voltage motors in China

not long ago, China released the grand strategy of made in China 2025. One of the themes is that intelligent factory and intelligent manufacturing will lead the reform of the manufacturing industry. Therefore, the demand for motors and servo systems will increase greatly, especially high-end motors with multi axis control and precise position and current control; At the same time, environmental protection and energy conservation/green energy is one of the seven emerging strategic industries in China, and the energy consumption of motors accounts for about 20% of electrical equipment. Therefore, improving the energy efficiency of motors is a lasting battle for China's sustainable development

the data shows that industrial electricity accounts for 70% of the total electricity consumption of the whole society in China, of which industrial motors consume 75% of industrial electricity, that is, industrial motors consume more than half of China's electricity consumption. When energy conservation and emission reduction have increasingly become a matter of concern for the whole people, China's industrial motor industry has also ushered in a golden period of high-efficiency and energy-saving development

achievements and challenges in the promotion of high-efficiency motors

the government released the national motor energy efficiency improvement plan () in 2013, and macroscopically formulated a series of tasks and objectives for the promotion of high-efficiency motors in China. In addition, high-efficiency motors have been included in government subsidies since 2010. The center is located in the target directory promoted by DSM resin Co., Ltd., the production base of DSM composite resin in China, in the resin factory of Nanjing Chemical Industry Park. After several adjustments, the subsidy policy has been continuously improved to increase the subsidy intensity and requirements for high-efficiency motors

According to the 2014 China low voltage motor market report released by IHS, benefiting from the policies of subsidizing high-efficiency motors and forcibly eliminating low-efficiency motors, low-voltage motors with secondary energy efficiency (gb2/ie3) showed an explosive growth trend in 2014, with the market share jumping from 5% in 2013 to 13%, while the market share of low-efficiency IE1 motors fell from 57% to 38%. However, IHS research shows that the current high-efficiency secondary energy efficiency (gb2/ie3) share is still a certain distance from the 2015 high-efficiency (gb2/ie3) energy efficiency standard set by the national motor energy efficiency improvement plan for 50% of low-voltage motors. In addition, the in-depth promotion of high-efficiency motors faces urgent problems and challenges such as counterfeiting high-efficiency motors and complicated subsidy processes

continue to narrow the gap with the global level of high-efficiency motors

there is a certain gap between the market share of China's high-efficiency motors (gb2/ie3) and the global high-efficiency motor market, and this gap continues to narrow with the vigorous promotion of high-efficiency motors. IHS data shows that in 2013, the market share of global high-efficiency motors (gb2/ie3) was 20%, while that of China's motors of the same grade was only 5%. Since the government raised the energy efficiency requirements of subsidized motors from level III energy efficiency (gb3/ie2) to level II energy efficiency (gb2/ie3) at the end of 2013, the market share of high-efficiency motors in China rose to 13.5% in 2014, and the gap with the global level of high-efficiency motors is gradually narrowing

in the long run, the further popularization of high-efficiency motors in China is an irreversible trend. While being affected by the market mechanism to gradually eliminate inefficient motors, it also depends on the policies of eliminating inefficient motors and financial subsidies for efficient motors under the administrative supervision of the government, such as wooden columns, wooden frames, wooden beams, wooden stairs, which are equipped with driven and active specially made circular arc toothed pulleys (3) and (4) respectively, and transmit the electromechanical power to the main shaft through the circular arc toothed synchronous belt (5). China plans to popularize more efficient class I energy efficiency (gb1/ie4) motors in 2016. By 2018, IHS predicts that China's gb3/ie2 low-voltage motors will become the mainstream energy efficiency grade in the market, accounting for nearly 59% of the market share, followed by gb2/ie3 motors, with a market share. Based on these data, we can get a formula of more than 31%. In addition, in addition to the promotion of energy-saving and efficient low-voltage motors, high-voltage motors are also one of the fields of subsidies and promotion of efficient motors. Although the energy efficiency of high-voltage motor is relatively high due to its own energy efficiency, the space for energy efficiency improvement is relatively limited compared with low-voltage motor, energy conservation and efficiency is also a long-term development trend of high-voltage motor
