Eddy currents are at the origin of losses and signal distorsions in power electrical. In order to address their considerable impacts on both the energy efficiency and the performance requirement, eddy current modeling and its accuraccy are discussed from a thermodynamic approach. Whereas adaptive meshing strategies were extensively used in static cases, some valuable results are carried out in an induction machine case-study, providing a general validation for transient regimes.
