Development of an Improved Methodology of Calculation of Parameters of an Asynchronous Motor Equivalent Circuit Using Experimental Data Obtained on the Basis of a Specialized Measuring Complex

Abstract

In the paper the existing methods for calculating the parameters of the equivalent of asynchronous motor circuit based on rated parameters has been analyzed. The simplified engineering methods for calculating the parameters of the equivalent of asynchronous motor circuit, presented in Russian and foreign literature, have been considered and an improved method for determining the parameters of asynchronous motor using experimental data obtained on the basis of a specialized measuring complex has been developed. On the basis of developed mathematical model of asynchronous motor with a squirrel cage, the accuracy of calculating the parameters of the equivalent circuit diagram, calculated on the basis of simplified and improved methods, has been verified.
