三相异步电动机效率特性快速量化方法
A Novel Method to Quick Acquire Efficiency Characteristics for Three-phase Induction Motors
摘要
Abstract
A variety of losses in the energy conversion process of the motors was taken into ac-count,based on the power loss analysis and the loss model in d-q coordinate of the three-phase induc-tion motors,a general model of load ratio and efficiency for motors was established.Only three groups of tests were needed to carry out in the same test conditions with varying load ratio,and based on the developed model,the efficiency characteristic curves would be obtained.Based on the experi-mental system for the efficiency test of motors,a comparison between the traditional point by point testing results and the proposed testing results was performed to determine the correctness and accu-racy of the developed efficiency model.The results show that the developed efficiency models are in good agreement with the experiments and the maximum absolute deviations are within 1%.关键词
