Abstract

L'invention porte sur un agitateur très robuste à aimants permanents comprenant: un cadre (3); un arbre principal (14); un disque tournant (13); des aimants permanents (15); et un couvercle de sécurité (9) non magnétique. L’arbre (14) est vertical et son extrémité supérieure à laquelle est fixé le disque (13) traverse le cadre (3). Le disque (13), horizontal, comporte plusieurs aimants permanents (15) fixés à sa surface supérieure. Les aimants permanents (15), disposés de manière à former une boucle fermée du pôle nord au pôle sud, sont faits de Nd-Fe-B, et sont placés dans la chambre du couvercle (9) fixé au cadre (3). Le couvercle (9) comporte à sa partie haute une plaque (12) non métallique thermorésistante arrondie et un dispositif de refroidissement par air. La partie inférieure de l’axe (14) est reliée à un mécanisme de freinage (1) fixé à la surface inférieure du cadre (3). L’arbre d’entraînement du mécanisme de freinage (1) est couplé à l’arbre d’un moteur (2) à vitesse variable commandée par modulation de fréquence. Le moteur (2), commandé par un contrôleur logique programmable (21) placé dans un boîtier, tourne alternativement dans un sens et dans l’autre, et entraîne les aimants permanents (15) alternativement dans un sens et dans l’autre en synchronisme via le mécanisme de freinage (1), l’arbre (14) et le disque (13). L’agitateur, très économe en énergie et sûr, peut s’utiliser dans les fours de fusion à sole plate d’usage courant.
