Abstract

L'invention concerne une structure de circuit magnétique, du type empilé, ayant des jambages extérieurs 14, 16, un jambage intérieur 18 et des culasses supérieure et inférieure 20, 22 formées d'une pluralité de groupes empilés de couches de tôles métalliques. Les dimensions en longueur des tôles de jambage et de culasse varient en directions opposées de couche à couche à l'intérieur de chaque groupe de couches, les points milieux des tôles étant en alignement dans chaque. jambage et chaque culasse. Cet agencement décale les extrémités des tôles de jambage et celles de culasse, de couche à couche, et donne un joint à gradins et recouvrement entre extrémités jointives des tôles de jambage et de culasse. Les positions relatives des tôles de jambage et de culasse sont choisies pour répartir uniformément les vides formés aux coins 86, 88, 90, 92 intérieurs du circuit magnétique entre les tôles de jambage et de culasse à l'intérieur de chaque groupe de couches de tôle.
