Modelling, Simulation and Monitoring of New Asynchronous Motor for EMU Train

In this paper there are presented the mathematical models, written in the two-axes theory, with and without saturation, for traction asynchronous motors used on the Electric Multiple Unit (EMU) train. The behaviour of a new motor rated at 430 kW has been simulated by means of these models, in different dynamic regimes. These simulations and the conclusions emerging from them are presented. In the last part of the paper there are presented a few tests which validate the simulations carried out.
