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 calculated start-up characteristics of the induction motor have been compared with the measurement results. On the basis of the obtained results, an analysis of rotor skew effect, skin effect and the saturation on the accuracy of the presented calculations have been undertaken.
