Abstract :
The paper presents a methodology for determination of harmonic iron losses in laminated iron cores under non sinusoidal excitation. The method is based on a convenient modification of Jiles-Atherton model to account for dynamic effects. The model tuning is performed by using measured hysteresis loops in iron laminations for sinusoidal excitation of various frequencies in Epstein device. An example of inverter fed induction motor is given showing that the method results are in good agreement with the experimental ones
