电动机效率试验方法对比研究

Comparative Research on Test Methods of Motor Efficiency

通过对北美、欧盟、日本JEC等国外电动机效率试验方法的分析,并与我国现行电机试验方法进行对比,发现主要存在负载杂耗测试上的差异。不同标准的试验方法,负载杂耗值选取的不同等,通过对比分析,得出我国高效及超高效电机效率应达到的水平。

Through comparing the existing test method of motor efficiency in our country with that in North America, European Union, Japan and other foreign countries, it is founded that the difference between them mainly occur in stray load loss test. The selected value of stray load loss is different based on the test methods in different standards. The efficiency level of high-efficiency and ultra-efficiency motor in our country to be reached is obtained by comparative analysis.
