China's high efficiency motor market is weak in international market
"Now there are fewer and fewer enterprises engaged in the production of traditional electric motors in developed countries such as Europe and the United States. China's electric motor enterprises may become their importers. The proportion of high-efficiency motors in domestic existing stock motors is less than 5%, and the production of high-efficiency motors is mainly Sold abroad. At the same time, the proportion of high-efficiency motors in China is currently only 23% to 25%." An efficient energy-saving motor manufacturer told reporters.
China has gradually become a major motor manufacturing country, mastering the production technology of high-efficiency and ultra-efficient energy-saving motors, but overall, the industry competitiveness is still weak. The amount of motor is large and the energy efficiency level is low. At present, China's overall energy efficiency level is still far from that of foreign countries, especially the energy-efficient use of electrical equipment such as motors and transformers. The amount of electricity used is large and the application area is wide. The electricity consumed by the motor per year accounts for 64% of the total social power consumption. The energy consumption of the field motor accounts for more than 70% of the total electricity consumption in the industrial field. The energy efficiency of the motor system is much different from that of the foreign country, which is about 15%~20%. Gao Dongsheng, deputy director of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, said.
According to the GB186132012 standard, China's current production and in-use motors are mostly Class 3 energy efficient motors that are lower than the standard. The average efficiency is 87%, and the efficient motor efficiency that has been implemented in developed countries has reached more than 91%. In addition, statistics from the Ministry of Industry and Information Technology show that at present, the proportion of high-efficiency motors in domestic motors is only about 5%. Academician Tang Renyuan, a well-known domestic motor expert, also pointed out that in recent years, although China has basically kept pace with the international level in the research and development of high-efficiency motors, the technological progress is very optimistic. But unfortunately, the IE3 motors produced in our country are used too little domestically, and most of them are used for export. It is not difficult to see that China still has huge challenges in high-efficiency motors.
"In the future, on the one hand, we should carry out in-depth research on energy-saving technologies for motors and their systems, such as research and development of energy-efficient motors; high-efficiency fans, pumps, compressor systems; high-efficiency transmission systems; reasonable matching of motor systems; and system integration solutions for energy-saving of motor systems. On the other hand, it is necessary to formulate guidelines and standards for energy-saving of motor systems, such as guidelines for system energy-saving retrofits, energy-saving testing and evaluation standards for motor systems in special fields, etc. In addition, it is necessary to establish a motor system energy-saving certification body, such as market-standard Into the certification, energy-saving product certification, all kinds of high-efficiency motors.
