Abstract
The paper presents a methodology for determination of harmonic iron losses in laminated iron cores under sinusoidal and non-sinusoidal excitation. The measurements are performed by using a convenient Epstein device supplied by a signal amplifier and are registered in a PC by using an appropriate data acquisition system. Eddy currents in iron laminations are modeled by finite element techniques while leakage field, respective inductances and losses are compared to measured ones.
