Our efficient motor development: there are achievements but remaining gap
2021-09-15
China has gradually become a manufacturing power motors, mastered the efficient and ultra-efficient energy-saving motors production techniques, but the overall look, industry competitiveness is still weak. Motor dosage, low levels of energy efficiency.
At present China's overall energy efficiency level there is a big gap with foreign countries, especially energy-efficient motors, transformers and other power equipment use, the amount of large, wide application area, the annual consumption of electricity by the motor consumes 64% of the whole society, industrial field motor energy consumption accounts for more than 70% of total industrial electricity consumption, the energy efficiency of motor systems consume more foreign than the difference, probably about 15% to 20%. Ministry of Industry and Information Technology Energy Saving and Comprehensive Utilization Department, Deputy Director Gao Dongsheng has said.
In accordance with the GB18613-2012 standard, China's current production and in motor much lower than standard requirements of three energy-efficient motors. The average efficiency of 87%, while the developed countries have already implemented efficient motor efficiency has reached more than 91%. In addition, statistics from the Ministry of Industry and Information Technology show that domestic motor efficiency motors in use accounted for only about 5%.
In recent years, although the basic research and development in high-efficiency motors to keep pace with international standards, technological progress is very optimistic. Unfortunately in our country the production of the domestic application of IE3 motors too little, mostly for export. It is not difficult to see that China is still a huge challenge in terms of high-efficiency motors.
Future, on the one hand to carry out the electrical system and its energy-saving technologies, such as the development of energy efficient motors; efficient fans, pumps, compressors system; efficient transmission; reasonable matching motor system; motor system and other systems integration solutions for energy saving. On the other hand to develop motor system energy-related guidelines, standards, such as the system of energy-saving guidelines, special areas of motor system energy saving test and evaluation standards. In addition, but also to establish motor system energy certification bodies, such as market access certification, energy-saving product certification, all types of energy-efficient motor system certification.
