Abstract

Noyau magnétique (2) fabriqué avec du ruban de verre métallique ferromagnétique et un isolant en papier de mica (1). Le ruban et l'isolant sont enroulés ensemble, de sorte que les couches comportent des anneaux concentriques de chacune des matières par alternance. Le noyau enroulé est ensuite recuit dans des conditions de vide ou dans une atmosphère inerte telle que de l'azote sec ou du gaz argon. Des noyaux enroulés de ce genre offrent d'excellentes propriétés magnétiques à des taux de magnétisation élevés et des blocages de courant élevés entre les structures lamifiées adjacentes; ils conviennent tout particulièrement pour les applications de courant pulsé.
