Motor efficiency and shorten the difference in foreign countries
Our country has gradually become the motor manufacturing country, have efficient and high efficiency energy saving motor production technology, but on the whole, the competitiveness of the industry is still weak. A large amount of energy efficiency, low level of motor.
"At present China's overall energy efficiency level and abroad there is a big gap, especially motor, transformer and power consumption equipment energy use, dosage, application of wide area, each year through the motor power consumption accounted for the whole society electricity consumption 64%, industrial area of motor energy consumption accounts for 70% of the total electricity use in industrial field, energy consumption of the motor system and abroad than more, probably around 15%~20%." The Ministry of industry and information technology energy saving and comprehensive utilization of deputy director of Gao Dongsheng said.
According to the GB18613-2012 standard, China's current production and in use motor for Level 3 lower than the standard motor. The average efficiency of 87%, while the efficiency motors developed countries have already implemented has reached more than 91%. In addition, the statistics from the Ministry of industry and information technology, at present in the domestic high performance motor accounted for only about 5%.
In recent years, although our country in high efficiency motor development and international levels remain very optimistic synchronization, technological progress. But it is a pity that our national production of IE3 motor domestic application of too little, most for export. It is not difficult to see, our country also has a huge challenge in the high efficiency motor.
"In the future, on the one hand to carry out the motor system energy saving technology research and development, such as energy efficient motor; high efficiency fan, pump, compressor system; efficient transmission system; the reasonable matching motor system energy-saving motor system; system integration scheme etc.. On the other hand, to develop energy-saving related guidelines, standard motor system, such as special guidelines, energy transformation system in the field of motor system energy saving detection, evaluation standard. In addition, but also to establish motor system energy saving certification bodies, such as market access certification, energy-saving product certification, high efficiency motor system energy-saving certification."
