Title
(EN) BULK AMORPHOUS METAL MAGNETIC COMPONENT
(FR) COMPOSANT MAGNETIQUE METALLIQUE AMORPHE RAPPORTE
Abstract
(EN)
A bulk amorphous metal magnetic component has a plurality of layers of amorphous metal strips laminated together to form a generally three-dimensional part having the shape of a polyhedron. The bulk amorphous metal magnetic component may include an arcuate surface, and preferably includes two arcuate surfaces that are disposed opposite each other. The magnetic component is operable at frequencies ranging from between approximately 50 Hz and 20,000 Hz. When the component is excited at an excitation frequency 'f' to a peak induction level Bmax, it exhibits a core loss less than 'L' wherein L is given by the formula L = 0.0074 f(Bmax)1.3+ 0.000282 f1.5(Bmax)2.4, said core loss, said excitation frequency and said peak induction level being measure in watts per kilogram, hertz, and teslas, respectively. Performance characteristics of the bulk amorphous metal magnetic component of the present invention are significantly better when compared to silicon-steel components operated over the same frequency range.

Composant magnétique métallique amorphe rapporté qui possède une pluralité de couches de bandes métalliques amorphes stratifiées ensemble pour former une pièce généralement tridimensionnelle ayant la forme d'un polyèdre. Ledit composant peut comporter une surface incurvée, et comporte de préférence deux surfaces incurvées qui se trouvent à l'opposé l'une de l'autre. Ce composant peut fonctionner à des fréquences situées entre environ 50 Hz et 20.000 Hz. Lorsqu'il est excité à une fréquence d'excitation 'f' jusqu'à une induction maximale Bmax, il présente une perte dans le noyau inférieure à 'L', L étant donné par la formule L = 0,0074 f(Bmax)1,3+ 0,000282 f1,5 (Bmax)2,4. La perte dans le noyau, la fréquence d'excitation et le niveau d'induction maximal sont mesurés respectivement en watts par kilogramme, hertz et teslas. Les caractéristiques de performance du composant magnétique métallique amorphe rapporté selon la présente invention sont considérablement meilleures que celles des composants silicium-acier fonctionnant sur la même plage de fréquences.
