Investigation of Idle Running and Short-Circuit Performance Improvement for an Asynchronous Traction Motor

2019 International Conference on Electromechanical and Energy Systems (SIELMEN), 2019
It is proposed the possibility to simulate the idle running and short-circuit performance of an asynchronous traction motor. These tests are important, as they allow for the calculation of the motor parameters.

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.
