heal.abstract	Iron loss analysis is important for transformer and electrical machine design. Especially, operation under distorted grid voltage waveforms and variable speed motors supplied by inverters present increased iron losses due to harmonic frequencies. The paper presents a methodology for determination of variable frequency iron losses in laminated iron cores under sinusoidal excitation. The method is based on a convenient modification of Jiles-Atherton model enabling 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. ©2008 IEEE.	en
