Abstract

a. Noyau formé de quatre parties formant une section transversale en croix. b. Noyau caractérisé en ce que chaque partie comprend deux branches en L, la première et la seconde partie étant assemblées en une section en T, la troisième et la quatrième partie étant juxtaposées en une section en U, les quatre parties etant assemblées de telle manière que soient formées par une portion de tronc et une portion transversale en croix, les parties étant formées d'empilages d'éléments stratifiés à section en forme de L. c. Noyau applicable à la constitution d'éléments inducteurs de transformateurs ou analogues.at. Core formed of four parts forming a cross section. b. Core characterized in that each part comprises two L-shaped branches, the first and second part being assembled in a T-section, the third and the fourth part being juxtaposed in a U-section, the four parts being assembled in such a way that are formed by a trunk portion and a cross section, the portions being formed of stacks of L-shaped sectional laminate elements. c. Core applicable to the constitution of inducing elements of transformers or the like.
