INFLUENCE OF ELECTROMAGNETIC PARAMETERS OF AN ASYNCHRONOUS MOTOR WITH A SHORT-CIRCUITED CAGE ON TRANSIENT PROCESSES

The article discusses the electromagnetic parameters of an asynchronous motor (AD) with a short-circuited cage of general industrial application for the study of transient processes in an electric drive. The main purpose of the study is to determine the transient characteristics of AD by comparing parameters with reference data and calculations in the ANSYS Maxwell RMxprt program. The parameters defined in the program were found to provide more accurate results for transients. The comparative analysis showed that the active resistance of the stator winding coincides with the reference value, while the inductance is 21 % lower and the mutual inductance is 26 % higher. The use of these parameters in the mathematical model of AD made it possible to obtain more accurate results in comparison with traditional reference values, which contributes to a better understanding of transient processes. The obtained results emphasize the importance of using modern tools, such as ANSYS Maxwell RMxprt, in the study of electromagnetic parameters to increase the accuracy of modeling transient processes in AD, which is relevant for optimizing their designs and operational characteristics.
