Presentation and experimental validation of a behavioral model of dynamic properties for magnetic materials

The presented work constitutes a contribution to dynamic behavioural models of the magnetic circuits of electrical actuators. We propose an original model for the representation of the microscopic dynamic effects in the magnetic materials. This model attached together with the classic magnetic field diffusion equation resolution allows to describe completely the whole dynamic effects in a magnetic lamination. This model which needs only one parameter penalises a little the calculation time respect to the improvement of the results. An experimental validation considering different wave-form excitations and frequencies has shown that this parameter can be assumed as constant for a wide area of excitation solicitations
