以IE5能效等级为目标，利用铸铜转子技术、低压不等匝绕组技术、低损耗硅钢材料等技术进行设计，已经研制出三相异步电动机测试样机。为准确测量三相异步电动机现场运行效率，主要依据GB/T 1032—2012 《三相异步电动机试验方法》，采用A法、B法和E1法对样机进行能效测试比对，研究并分析3种测试方法的差异。测试的3个系列IE5能效等级样机中，B法计算效率均能达到GB 18613—2020 《电动机能效限定值及能效等级》中1级能效的要求。

Three-phase asynchronous motor test prototypes with IE5 energy efficiency grade have been designed and developed by using cast copper rotor technology, low-voltage unequal turn winding technology, low loss silicon steel material and other technologies. In order to accurately measure the field operation efficiency of three-phase asynchronous motors, the energy efficiency comparison test of the developed prototypes is carried out by using methods A, B and E1 according to the national standard GB/T 1032—2012 Test procedures for three-phase induction motors, and the differences among the three test methods are studied and analyzed. For the three series of IE5 energy efficiency grade prototypes tested, the calculation efficiency of method B can meet the requirements of grade-1 energy efficiency in GB 18613—2020 Minimum allowable values of energy efficiency and values of efficiency grades for motors.
