Title (EN) TAPE-WOUND CORE, AND METHOD FOR PRODUCING TAPE-WOUND CORE
(FR) NOYAU ENROULÉ SUR BANDE ET PROCÉDÉ DE PRODUCTION DE NOYAU ENROULÉ SUR BANDE
(JA) 巻磁心及び巻磁心の製造方法
Abstract:
(EN) This tape-wound core is obtained by winding an amorphous alloy ribbon which has a composition represented by Fe100-a-bBaSibCc, is cuttable, and has an iron loss at a frequency of 50 Hz and a magnetic flux density of 1.3 T of not more than 0.3 W/kg. a and b represent atomic ratios in the composition, and respectively satisfy 13.0 atom%≤a≤16.0 atom%, and 2.5 atom%≤b≤5.0 atom%. c represents the atomic ratio of C to 100.0 atom% of the total amount of Fe, Si, and B, and satisfies 0.20 atom%≤c≤0.35 atom%.
(FR) L'invention concerne un noyau enroulé sur bande qui est obtenu par enroulement d'un ruban d'alliage amorphe qui a une composition représentée par Fe100-a-bBaSibCc, qui peut être coupé, et qui présente une perte de fer à une fréquence de 50 Hz et une densité de flux magnétique de 1,3 T inférieure ou égale à 0,3 W/kg. Les éléments a et b représentent des rapports atomiques dans la composition, et satisfont respectivement 13,0 % atomique ≤ a ≤ 16,0 % atomique, et 2,5 % atomique ≤ b ≤ 5,0 % atomique. L'élément c représente le rapport atomique de c à 100,0 % atomique de la quantité totale de Fe, Si et B, et satisfait à 0,20 % atomique ≤ c ≤ 0,35 % atomique.
(JA) 本開示の巻磁心は、Fe100-a-bSiで表される組成を有し、裁断性を有し、かつ、周波数50Hz、磁束密度1.3Tの条件での鉄損が0.3W/kg以下であるアモルファス合金リボンが巻回されている。a及びbは、組成中の原子比を表し、それぞれ13.0原子%≦a≦16.0原子%、2.5原子%≦b≦5.0原子%を満たす。cは、Fe、Si及びBの合計量100.0原子%に対するCの原子比を表し、0.20原子%≦c≦0.35原子%を満たす。
