| 摘 要： | 本文阐述了在微型电子计算机上运用计算数学中曲线拟合的方法处理三相异步电动机的测试数据,取得了满意的结果。由于现代微机的强大运算功能和绘图能力,尽管反映电机各种特性的曲线形状相差很大,用曲线拟合程序都能获得逼近度较高的光滑曲线。这用获得的拟合曲线进行插值计算,即可得到电机的各个参数。与手工分析比较,这种方法不仅节约了繁重的计算工作量,而且提高了分析精度。文章还提出了运用短路试验和负载试验所获得的结果,求取三相异步电动机机械特性的简易方法。

| Abstract: | The application of microcomputer for the processing of testing data for three phase induction motors using the mathematical method of least square curve fitting is presented. The process results are satisfactory. Duc to the high computing power and excellent graphic capability of modern microcomputers, Various smooth characteristic curvcs can be obtained with close approximations using the curve fitting program, and the individual parameters can easily be obtained through interpolation. Both the accuracy and the data proccssing speed are greatly increased in comparison with the manual method. In addition, a simple and straightforward method for obtaining the speedtorque curve of induction motors using the results of locked-rotor test and load test is proposed in this paper. |
