Technical Electrodynamics| Summary: | A complex coupled-field multiphysics mathematical model to describe the electromagnetic, thermal, and ventilation processes in a traction induction motor has been developed. This model takes into account the mutual influence of these processes on the characteristics of the motor, ensuring high accuracy of the simulation results, that distinguish it from existing approaches and mathematical models. The model is implemented on the example of a serially-produced motor STA-1200, with a capacity of 1200 kW, characterized by high level of electromagnetic and thermal loads, used in train locomotives. Although the design of the series-production STA-1200 was considered optimal, the application of the developed multiphysics model has allowed for additional recommendations to improve its performance by accurate considering the mutual influence of different physical processes occurring during its operation. Specifical ly, when operating in the same nominal operation mode, the improved motor has better specific mass-dimensional and energy characteristics compared to the serially-produced STA-1200.
