Formulations intégrales magnétostatiques 2D dédiées au pré-dimensionnement des machines électriques tournantes

Abstract : This PhD thesis aims to develop an alternative method to the finite elements method for an efficient electrical rotating machines pre-design.Electrical engine pre-design involve of a quick calculation of the magnetic field within the rotating machine and be able to extract of this field the main physical characteristics of the machine. The physical characteristics searched for are the magnetic torque applied on the rotor and the magnetic flux through the coils of the engine.After a quick review of the existing methods for electrical engine pre-design, integral methods developed in Grenoble electrical laboratory will be took on to carry out the calculation of the magnetic field in the engine. Those methods allow a fast and precise calculation of the magnetic field thanks to an excellent evaluation of the interaction between the elements of the mesh.The integral formulation used in this thesis is a vector potential volume integral formulation where the vector potential is interpolated over the edges of the mesh. This formulation has been adapted to the specificities of the electrical engine simulation and optimized for the case of multi-static computations. Finally, original post functions have been developed to compute the physical characteristics of the electrical engine from the magnetic field solution provided by the volume integral formulation. Two methods of torque computation are presented along with one semi-analytical method for the computation of the flux through the coils of the engine.This study brings out that the coupling between the vector potential volume integral method and the post functions described above provides good results faster than the finite elements method for several physical characteristics of the electrical machine.
