Abstract
(EN)
This core is used in an axial gap type rotating electric machine and is provided with: an annular yoke having a plurality of through holes disposed in the circumferential direction; and a plurality of columnar teeth each having one end inserted into each of the plurality of through holes and arranged side by side in the circumferential direction of the yoke. The yoke and each of the teeth are configured by mutually independent green compact moldings, and the one end of each of the teeth is disposed by being deviated within the through holes.
(FR)
L'invention concerne un noyau qui est utilisé dans une machine électrique tournante de type à entrefer axial et qui est pourvu : d'une culasse annulaire ayant une pluralité de trous traversants disposés dans la direction circonférentielle ; d'une pluralité de dents en colonne ayant chacune une extrémité insérée dans chaque trou de la pluralité de trous traversants et agencées côte à côte dans la direction circonférentielle de la culasse. La culasse et chacune des dents sont configurées au moyen de moulages compacts verts, indépendants les uns des autres, et la première extrémité de chacune des dents est disposée de façon déviée à l'intérieur des trous traversants.
