Abstract

Ce circuit magnétique pour appareils électriques à induction tels que selfs, comprend un cadre composé de culasses et au moins une branche de noyau 3 disposée dans le cadre entre les deux culasses 1, 2. Entre les extrémités de la branche du noyau et les culasses, il est interposé des plaques de flux transversal 4 en une matière magnétique feuilletée. La stratification dans ces plaques doit être à angle droit par rapport à la stratification dans les culasses. La plaque de flux transversal doit recouvrir au moins toute la largeur de la culasse et toute la largeur de la branche de noyau. La plaque a une largeur égale au diamètre de l'enroulement placé autour de la branche de noyau pour qu'elle serve d'appui mécanique pour les extrémités de l'enroulement. Il est opportun de placer des couches intermédiaires de matière non magnétique entre l'extrémité de la branche de noyau et la plaque, ainsi qu'entre la plaque et la culasse.
