Abstract

This paper deals with the numerical computation of the average induction over sheet laminations by solving the magnetic diffusion equation. Different models are used to describe the magnetization law: an anhysteretic law and the static and dynamic hysteresis Preisach models. The computed flux and associated losses are then compared to experimental results for wide frequency range and different magnetization levels
