¡¡¡¡China has gradually become a large motor manufacturing country,and has mastered the production technology of efficient and super efficient energy-saving motors.However,the overall competitiveness of the industry is still weak.Large motor consumption and low energy efficiency.
¡¡¡¡At present,China's overall energy efficiency level still lags far behind that of foreign countries.In particular,the energy efficiency use of electric machines,transformers and other power consuming equipment is large and widely used.Every year,the electricity consumed by motors accounts for 64%of the total electricity consumption of the whole society.The energy consumption of industrial motors accounts for more than 70%of the total electricity consumption of industrial fields.The energy efficiency consumption of motor systems is more different from that of foreign countries,about 15%~20%.Gao Dongsheng,Deputy Director of the Energy Conservation and Comprehensive Utilization Department of the Ministry of Industry and Information Technology,once said.
¡¡¡¡According to the GB18613-2012 standard,most of the motors produced and in use in China are lower than the level 3 energy efficiency motors specified in the standard.Its average efficiency is 87%,and the efficiency of high efficiency motor 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 the proportion of high-efficiency motors in use in China is only about 5%.
¡¡¡¡In recent years,although China has basically kept pace with the international level in the research and development of efficient motors,technological progress is very optimistic.Unfortunately,IE3 motors produced in our country are seldom used in China,and most of them are used for export.It is not difficult to see that there are still huge challenges in terms of efficient motors in China.
¡¡¡¡In the future,on the one hand,it is necessary to carry out in-depth research on energy-saving technologies of motors and their systems,such as research and development of high-efficiency energy-saving motors;High efficiency fan,pump and compressor system;Efficient transmission system;Reasonable matching of motor system;System integration scheme for energy saving of motor system,etc.On the other hand,it is necessary to formulate relevant guidelines and standards for motor system energy conservation,such as guidelines for system energy conservation transformation,energy conservation testing and evaluation standards for motor systems in special fields,etc.In addition,it is also necessary to establish energy-saving certification institutions for motor systems,such as market access certification,energy-saving product certification,and energy-saving certification for various high-efficiency motor systems.
