Abstract
La présente invention a pour objet un procédé de fabrication d'au moins un tore magnétique (1) pour capteur de courant continu, ce procédé étant caractérisé en ce que ledit tore (1) est réalisé par juxtaposition de plusieurs couches (2a,2b,2c,2d) constituées chacune par une bande constituée d'un film réalisé en un matériau magnétique, puis fixation desdites couches juxtaposées les unes aux autres de manière à réaliser une bande, puis réalisation du tore à partir de la bande, la section du tore (1) étant dépendante du nombre de couches juxtaposées. La présente invention a encore pour objet un tore (1) réalisé suivant ce procédé.The subject of the present invention is a method of manufacturing at least one magnetic core (1) for a direct current sensor, this method being characterized in that said core (1) is produced by juxtaposition of several layers (2a, 2b, 2c, 2d) each consisting of a strip consisting of a film made of a magnetic material, then fixing said layers juxtaposed to each other so as to produce a strip, then producing the torus from the strip, the section of the torus (1) being dependent on the number of juxtaposed layers. The present invention also relates to a torus (1) made using this process.
