Abstract

Dispositif de protection pour un organe d'alimentation de machine équipé d'un moteur à courant continu. Il comprend un moyen de détection pour mesurer la vitesse de rotation de l'arbre principal du moteur, un moyen de comparaison pour émettre des signaux de commande basés sur la différence mesurée entre la vitesse de rotation ainsi mesurée et une vitesse de rotation prédéterminée, un moyen de réglage pour limiter ces signaux de commande à une valeur prédéterminée au cas où ces signaux de commande sont au-delà de la valeur autorisée, et un moyen de réglage de courant d'induit pour régler le courant arrivant à l'induit du moteur à courant continu en fonction de ces signaux de réglage. Application : protection pour machines comportant une table de travail.
