Prédiction de signatures électriques dans un actionneur en prenant en compte les lois de matériaux

Abstract : In an electromagnetic actuator, the magnetic circuit's main function is to beam the electromagnetic energy to the desired zone (the air-gap). In this magnetic circuit, some energies of different natures are transformed, stored, exchanged and dissipated. The performances of the softwares to represent the transient states and the losses depends on the way that the softwares evaluates all these kinds of energy. This imposes to the model to be able to describe , in transient state, all the history of the material magnetization.
Our work is basing on developping simulation tools in which the magnetic circuit is a part of the heart of the energetic conversion. Some simplifying assumptions or/and couplings between methods a priori or in real time authorize us to study the transient states inside the magnetic circuits and to evaluate the losses.
the coupling between the methods and the associated assumptions are described following the chapters. The results allow the fine analysis of the magnetic circuit function for several industry-oriented systems and the reflexion on eventual improvements to bring to these systems
