Abstract

L'invention porte sur un transformateur et plus particulièrement sur un système et un procédé de fabrication d'un transformateur recourant à une technique de compaction magnétodynamique comportant les étapes suivantes: mise en place dans une enceinte conductrice d'une bobine et d'un matériau pulvérulent conducteur tel que de la ferrite entourant la bobine et ses spires; alimentation d'un condensateur produisant un puissant courant énergétique dans une deuxième bobine entourant l'enceinte, le matériau pulvérulent et la première bobine, ce qui provoque la compaction de l'enceinte, du matériau pulvérulent et de la bobine . On peut ainsi réaliser un composant électrique tel qu'un transformateur, un moteur, un commutateur, un rotor ou une bobine d'arrêt.
