论述了我国三相异步电动机产品的发展过程,主要代表产品有JO、JO2、Y、Y2、Y3、YX3、YE2、YE3等系列三相异步电动机。介绍了自1978年起我国三相异步电动机系列产品采用国际标准的情况,以及近几年等同采用国际标准IEC 60034-30的情况,并结合我国中小型电机产品的实际情况,对三相异步电动机的能效分级进行了分析浅议。

The development process of China′s threephase asynchronous motor were discussed, the main representative products were JO, JO2, Y, Y2, Y3, YX3, YE2, YE3 series threephase asynchronous motor. The international standard of threephase asynchronous motor series products since 1978 were introduced, and Equivalent to the adoption of international standard IEC6003430 in recent years and combined with the actual situation of small and medium motor products in China, the energy efficiency classification of threephase asynchronous motors was analyzed.
