To Explore High Precision Calculating Method for Induction Motor's Equivalent Circuit Parameter

本文提出了一种用计算机进行三相异步电动机等效电路参数高精度计算的方法。该方法根据电动机的空载试验、堵转试验及负载试验的实验数据。通过计算机不断计算修正 ,使等效电路参数理论计算值逐步收敛于实验值。同时将本方法与现行各主要等效电路参数精度计算方法进行比较探讨。

A high precision method of calculating equivalent circuit parameters of 3 phase induction motor is discussed in this paper. Based on the experimental data of the motor under unload test, blocked test and load test, with the continuous calculation and modification using a computer, the theoretical equivalent circuit parameters will finally approach the experimental value. At the same time, compared and studied the differences between this method and the current foreign high precision calculating methods.Proved that the new calculation method is correct and practicable.
