Abstract

Le noyau de fer pour bobine ou transformateur comporte selon la présente invention, un empilement de tôles en T 1 et deux empilements de tôles en L 2. Les faces supérieures des branches des L sont biseautées 5 ainsi que les extrémités des branches horizontales des L. L'entrefer est déterminé par une tige passant dans une rainure pratiquée dans la face inférieure de la branche du T. Grâce à l'invention, on minimise les pertes en tôle lors du poinçonnage.
