摘　　要：简述使用定子叠频法对无法采用对拖负载法进行温升试验的交流异步电机进行温升试验的基本原理及试验方法,分析了其数据的准确性、优势与缺点,并将叠频法与现使用的直流负载反馈法进行比较。The basic theory and methods of temperature -rise test of 3 phase induction motor by using frequencysuperposition method was described when direct mechanical back-to-back method was unavailable. Veracity of test data as well as the advantage and disadvantage of frequency-superposition method was analyzed too. Finally, the frequency-superposition method was compared with the DC electrical back-to-back test used in our station.
