Abstract
(EN)
A laminated iron core (10) that has: ring-shaped iron core pieces (14) that are formed by arranging magnetic arc-shaped iron core pieces (12) in a ring; and a laminate iron core body (16) that is formed by laminating a plurality of the ring-shaped iron core pieces (14). The laminated iron core (10) also has: first weld parts (18A) that are provided to the laminated iron core body (16) along the lamination direction of the ring-shaped iron core pieces (14); and second weld parts (18B) that are provided to a portion of the ring-shaped iron core pieces (14) and extend from an outermost ring-shaped iron core piece (14) toward the lamination-direction inside.
(FR)
Un noyau de fer stratifié (10) qui a : des pièces de noyau de fer en forme d'anneau (14) qui sont formées par agencement de pièces de noyau de fer en forme d'arc magnétique (12) en un anneau ; et un corps de noyau de fer stratifié (16) qui est formé par stratification d'une pluralité des pièces de noyau de fer en forme d'anneau (14). Le noyau de fer stratifié (10) comprend également : des premières parties de soudure (18A) qui sont disposées sur le corps de noyau de fer stratifié (16) le long de la direction de stratification des pièces de noyau de fer en forme d'anneau (14) ; et des secondes parties de soudure (18B) qui sont disposées sur une partie des pièces de noyau de fer en forme d'anneau (14) et s'étendent à partir d'une pièce de noyau de fer en forme d'anneau (14) le plus à l'extérieur vers l'intérieur de la direction de stratification.
