Abstract
L'invention concerne des circuits magnétiques, nouveaux et perfectionnés pour les appareils électriques inductifs, et des procédés nouveaux et perfectionnés de construction d'un appareil électrique qui facilite la fabrication d'un tel appareiL Les circuits magnétiques nouveaux et perfectionnés sont du type empilé, et ils utilisent différents joints à gradins et recouvrement entre culasses 32, 34 et jambages 26, 28 choisis du circuit magnétique. Les procédés nouveaux et perfectionnés comportent les phases de pré-empiler les jambages, empiler la culasse inférieure pendant que les jambages sont pratiquement orientés horizontalement, partir d'un flanc des jambages et progresser vers l'autre flanc, et empiler la culasse supérieure tandis que les jambages sont pratiquement orientés verticalement, en partant pratiquement des points milieux des jambages et progresser vers l'extérieur dans des directions opposées.
