High voltage motor standard
With China's accession to WTO, China's motor industry faces enormous pressure of competitionand international challenges. From the international and domestic development trend, promote theChinese high efficiency motor is very necessary, this is also the product development, make our country motor products to keep pace with the international trend, but also need to promote thetechnological progress of industries and products for export. According to statistics, in 2002 China'smotor power consumption accounted for more than 60% of the total power consumption, among which there are three small asynchronous motor power consumption accounted for about 35%, is the power consumption, so the development of Chinese efficient motor is one of the important measures to improve energy efficiency, meet the needs of the development of our country, it is very necessary.
Efficient motor motor is the universal standard motors with high efficiency.
High efficiency motors take measures from design, materials and processes, such as the use ofreasonable setting, the number of rotor slots, fan parameters and sine winding and other measures, reduce the loss, can improve the efficiency of 2%~8%, an average increase of 4%. In 2002, Chinese motor total capacity of about 400GW, of which nearly 80% small and medium, the annual electricity consumption of 660TW - H. Small and medium sized motor average efficiency of 87%, the international advanced level of 92%. Chinese in small motor power saving potential is about 12TW - H.
From the point of view of saving energy, Protect environment, high efficiency motor is an international trend, USA, Canada, Europe has promulgated relevant laws and regulations.According to the operation time of the motor of the European CEMEP standards, will be divided into eff1 (the highest efficiency), eff2, eff3 (minimum) three grades, from 2003-2006 years step by step.The latest IEC 60034-30 standard motor efficiency is divided into IE1 (corresponding to eff2), IE2(eff1, IE3, IE4 corresponding) (the highest) four grades. China's commitment to the implementation of IE2 and above standard since July 1, 2011.
