Simulation of thermal processes in asynchronous traction electric motor of a locomotive

This article analyzes the problem of increasing the reliability of AC traction electric machines installed on traction rolling stock. In the course of the study, a finite element model of thermal processes was built, and the thermal state of an asynchronous traction motor (ATED) of a diesel locomotive was studied in the Solid Works program. The basic method for studying thermal processes in ATED was the finite element method (FEM), as well as the basic equations of heat transfer and the theory of heating a multicomponent solid. The constructed finite element model of the ATED rotor of a diesel locomotive makes it possible to determine the dependence of the temperature values of the rotor elements on the current flowing through them. The obtained values of the temperature distribution of the ATED squirrel-cage rotor are recommended to be taken into account in the design, manufacture and testing of AC electric machines of diesel locomotives.
