Etude d'écrans supraconducteurs à haute température critique massifs : application à la réalisation d'une machine électrique de conception originale

Abstract : After a zero magnetic field cooling, high temperature superconductors are able to expel the flux lines out of their volume. We propose to use this property to make an inductor for electrical motors using superconducting shields to concentrate the flux density. As the theoretical study of this system requires the use of numerical calculation, we have developed a 3D magnetic field calculation tool based on a Markov chain Monte-Carlo method. This probabilistic method leads to a quantifiable error of calculation that we have minimized by using a signal regularization method. We have made the design of an inductor and have realized it. Thus, we have verified the efficiency of the structure and the efficiency of the calculation tools developed.
