Méthode tensorielle générale pour une modélisation multiphysique de dispositifs magnétomécaniques rapides

Abstract : Currently the goal of knowledge magnetomechanical devices is completed by means of several complementary approaches. On one hand the physical approach with mathematical formulations of magnetic forces. On the other hand, multiphysics approaches to achieve a deeper insight and more real, physical phenomena associated with interactions that act in the devices. And finally, the interdisciplinary approach that takes into account the lifecycle of the product, so called eco-design. A design of a ultra fast micromotor with induced magnetization and axial flux is presented in this paper with the physical approach showing the restrictions thereof. Accordingly therefore, the physical approach, a new tensor method is developed as a general contribution to a multiphysics modeling of magnetomechanical devices, bringing together the various numerical formulations of magnetic forces. A characterization of the new tensor is presented and applied to calculate the forces on bodies in contact.
