Abstract

L'invention a trait à des perfectionnements apportés aux machines électriques. Elle a pour objet une machine électrique statique ou dynamique, équipée d'un noyau de fer formé 'un grand nombre de couches distinctes. Le noyau de fer 1, il, 18, peut être composé de plusieurs éléments 1, 2, 12, 13, 19 se composant de couches feuilletées 1a, 2a, 12b, 13b, 19a, assemblées et adjacentes par l'intermédiaire de joints 1c, 2c, 12a, 13a, 19b réalisés pour qu'il en résulte une résistance magnétique variable, inversement proportionnelle à la longueur des lignes de force magnétiques 4, 5, et les joints, lorsqu'ils sont réalisés par enlèvement de matière, tel que par moulage, sont soumis à un traitement éliminant une liaison métallique, telle qu'une bavure de meulage, formée éventuellement entre les différentes couches, et en ce qu'entre les joints des différentes parties de noyau est prévu un matériau étranger 6, 17, 21. Application notamment à la réalisation de circuits magnétiques de machines électriques.The invention relates to improvements made to electrical machines. It relates to a static or dynamic electric machine, equipped with an iron core formed 'a large number of distinct layers. The iron core 1, 11, 18, can be composed of several elements 1, 2, 12, 13, 19 consisting of laminated layers 1a, 2a, 12b, 13b, 19a, assembled and adjacent by means of joints 1c , 2c, 12a, 13a, 19b made so that the result is a variable magnetic resistance, inversely proportional to the length of the magnetic lines of force 4, 5, and the joints, when they are produced by removing material, such as by molding, are subjected to a treatment eliminating a metallic bond, such as a grinding burr, possibly formed between the different layers, and in that between the joints of the different core parts is provided a foreign material 6, 17, 21. Application in particular to the production of magnetic circuits of electric machines.
