A Method and Approach to Determine the Equivalent Circuit Parameters of Miniature Three-Phrase Induction Motors

提出了一种小型三相异步电动机等效电路参数的计算方法。该方法根据三相异步电动机的空载试验、堵转试验、直流制动试验推导了可以分别求取三相异步电动机各等效电路参数的一整套公式,经对多台样机的实际测定与计算,证明其精度较传统的计算方法有明显的提高。

This paper describes a method to determine the equivalent circuit parameters of three-phrase induction motors.In the method, a whole set of formola to calculate different equivalent circuit parameters of such motors is set up based on free load test, lock test and DC brake test. The method has been applied to measurement and calculation on sample machines and results achieved are more accurate than those by classic methods.
