heal.abstract	This paper presents a methodology for determination of harmonic iron loss in laminated iron cores under nonsinusoidal excitation. The methodology adopted is based on a particular three-dimensional finite-element model by using a reduced scalar potential formulation. Eddy currents in iron laminations are considered by means of convenient surface current densities. Experimental verification is performed by comparing computed and measured leakage field. in an E-shape laminated core case. A convenient modification of induction motor equivalent circuit parameters is proposed, enabling consideration of switching frequency iron loss in case of inverter supply.	en
