The losses of induction motors driven by PWM inverters are analyzed using the finite element method considering the carrier harmonics. The calculated results are compared with the experimental ones. To consider the effect of the carrier, the theoretical voltage waveform due to the switching pattern of the inverter is given to the analysis by coupling the primary voltage equation and the finite element formulation. The method to decompose the electromagnetic field distribution into time-harmonic components is introduced in order to investigate the effects of the harmonic fields separately and to specify the main loss factors. It is clarified that the rotor surface loss especially increases due to the carrier and that the accuracy of the calculated characteristics of the motor is improved by considering the carrier.
