Additional losses of asynchronous induction machines utilized in traction drives caused by the inverter have a great impact of the thermal behaviour of such machines. Therefore, an accurate modelling and evaluation of these additional losses is a very important task in particular with the initial design. Based on detailed measurement data from already built machines, a fast and reliable calculation method of these additional losses suitable for the initial design of new machines is presented based on equivalent circuits of the induction machine for each higher harmonic components of the terminal voltages applied by the inverter.
