Abstract

Toles d'acier électrique à grains orientés ayant une faible perte en watts après le recuit de détente, ces toles d'acier, qui ont subi un recuit de texture finale, et auxquelles une tension est communiquée, comportent un certain nombre d'évidements sur leur surface formant des empreintes dans le corps en tole d'acier d'une profondeur de l'ordre de 0,01 à 0,1 mm, ces évidements étant remplis d'une composition ayant un coefficient de dilatation thermique plus petit que celui du corps en tole d'acier, les domaines magnétiques étant subdivisés à partir de ces évidements et de cette composition, leur procédé de production et appareil pour les obtenir.
