Magnetic field indicators of traction electric machines of rolling stock in the railway system of Uzbekistan

In this article, the application of numerical methods to determine the magnetic field parameters of traction motors operating on Uzbekistan's railways allows us to characterize their design features, which is necessary to complement existing mathematical models and determine the efficiency of traction motors as energy converters. The magnetic field vector potentials of traction motors under local conditions are calculated, including those of high-speed electric rolling stock, subway cars, electric locomotives, diesel locomotives, and a number of foreign models. Design and operational features are discussed, and comparative tables are provided.
