Title (EN) IRON CORE AND MOTOR USING SAID IRON CORE
(FR) NOYAU DE FER ET MOTEUR UTILISANT LEDIT NOYAU DE FER
(JA) 鉄心とその鉄心を用いたモータ
Abstract:
(EN) This iron core comprises: stacks of a plurality of fixed magnetic steel sheets; a stack of alloy thin bands sandwiched between the stacks of the magnetic steel sheets; a fastening mechanism penetrating through the stacks of the magnetic steel sheets and the stack of the alloy thin bands; and a mount base. The iron core has a structure in which the stack of the alloy thin bands including nanocrystal grains is vertically sandwiched between the stacks of amorphous alloy thin bands. In this way, compressive or torsional force acting on the stack of the alloy thin bands is decreased. This motor comprises a rotor and the iron core.
(FR) L'invention concerne un noyau de fer comprenant : des empilements d'une pluralité de feuilles d'acier magnétique fixes ; un empilement de bandes minces d'alliage pris en sandwich entre les empilements des feuilles d'acier magnétique ; un mécanisme de fixation pénétrant à travers les piles des feuilles d'acier magnétique et l'empilement des bandes minces d'alliage ; et une base de montage. Le noyau de fer a une structure selon laquelle l'empilement des bandes minces d'alliage comprenant des grains de nanocristal est pris en sandwich verticalement entre les empilements de bandes minces d'alliage amorphe. De cette manière, une force de compression ou de torsion agissant sur l'empilement des bandes minces d'alliage est réduite. Ledit moteur comprend un rotor et le noyau de fer.
(JA) 固定された複数の電磁鋼板の積層体と、上記電磁鋼板の積層体にはさまれた合金薄帯の積層体と、上記電磁鋼板ならびに合金薄帯の積層体を貫通する締結機構と、取付台と、を有する鉄心を用いる。また、上記合金薄帯の積層体は、ナノ結晶粒を有する合金薄帯の積層体の上下を、非晶質合金薄帯の積層体ではさんだ構造を有する鉄心を用いることで、合金薄帯の積層体に作用する圧縮やねじれの力を小さくする。さらに、回転子と、上記鉄心と、を含むモータを用いる。
