Abstract

NOYAU MAGNETIQUE POUR DES CHAMPS MAGNETIQUES TRIDIMENSIONNELS. IL PEUT ETRE CONSTITUE D'UN NOYAU CENTRAL 1 ET D'UN NOYAU EXTERIEUR 3, LE NOYAU CENTRAL 1 ETANT FORME DE TOLES EN FORME DE DISQUE DISPOSEES DE MANIERE A FORMER UN CYLINDRE ET LE NOYAU EXTERIEUR 3 DE TOLES RADIALES 4 DISPOSEES DE PREFERENCE SOUS LA FORME DE DEVELOPPANTE. POUR LE NOYAU CENTRAL, ON PEUT AUSSI UTILISER DES TOLES RECTANGULAIRES DISPOSEES DANS LE SENS DE LA LONGUEUR, ET POUR LE NOYAU EXTERIEUR DES TOLES DE FORME ANNULAIRE. LE NOYAU MAGNETIQUE PEUT AUSSI ETRE CONSTITUE DE FILS METALLIQUES DISPOSES PARALLELEMENT LES UNS PAR RAPPORT AUX AUTRES OU D'UN NOYAU EN POUDRE DE FER. APPLICATIONS A LA FABRICATION DE NOYAUX MAGNETIQUES.
