Calculation of asynchronous traction motor start-up characteristics by FEM method

International Symposium on Power Electronics Power Electronics, Electrical Drives, Automation and Motion, 2012
2D and 3D calculation of squirrel-cage traction motor start-up characteristics at rated voltage and frequency have been performed by using a numerical FEM based program. From the equivalent circuit parameters, which are obtained by analytical calculation, a simulation of a start-up using an analytical dynamic model was performed.

The Importance of the Cross Geometry over the Optimal Design of Asynchronous Traction Motors

2020 International Conference and Exposition on Electrical And Power Engineering (EPE), 2020
In electric traction, the motors that drive the railway vehicles consume a lot of active and reactive electricity, so the operating costs are high. Therefore, a reduction of the operating cost is proposed, through an optimal design of the asynchronous traction motors. This is a very difficult problem, assuming the knowledge of the operating conditions,
