Abstract: The authors present a novel nonlinear homogeniza- tion technique for laminated iron cores in 3D FE models of electromagnetic devices. It takes into account the eddy current effects in the stacked core without the need of modelling all laminations separately. A nonlinear constitutive magnetic law is considered. The system of nonlinear algebraic equations obtained after time discretisation is solved by means of the Newton-Raphson scheme. By way of validation the method is applied to a 3D FE model of a laminated ring core with toroidal coil.
