Abstract

Tôle de noyau d'une seule pièce comportant au moins une fenêtre, pour transformateurs, bobines d'induction, stabilisateurs ou analogues, dans laquelle, pour permettre l'insertion par une de ses parties dans une bobine, est prévue une séparation partant de sa fenêtre et s'étendant jusqu'à sont contour extérieur, tandis qu'un entrefer est ménagé entre les bords de séparation opposés. Cette tôle de noyau est caractérisée en ce que l'entrefer 9, 10 est formé par introduction partielle d'une déformation permanente 15 dans une zone éloignée dudit entrefer.One-piece core sheet comprising at least one window, for transformers, induction coils, stabilizers or the like, in which, to allow insertion by one of its parts into a coil, a separation is provided from its window and extending to its outer contour, while an air gap is formed between the opposite partition edges. This core sheet is characterized in that the air gap 9, 10 is formed by partial introduction of a permanent deformation 15 in a zone remote from said air gap.
