Abstract
L'invention a trait à un système régulateur de vitesse. Lorsque deux mécanismes d'entraînement à courant continu et à vitesse réglée sont reliés l'un à l'autre par une matière commune à traiter, par exemple un feuillard à laminer, la tension dans le feuillard est réglée par un système compensateur de couple. Les mécanismes d'entraînement à courant continu utilisent un système d'affaiblissement du champ pour la régulation de la vitesse et le courant du moteur seul n'est donc pas représentatif du couple. La vitesse du moteur est surveillée pour produire un signal omega m qui est une valeur par unité, la vitesse nominale du moteur étant considérée comme égale à l'unité Un signal compensateur de couple Vt est produit et est proportionnel au signal de courant d'induit Ia pour des valeurs de omega m =< 1, Vt étant égal à Ia / omega m pour des valeurs de omega m >= 1. Un diviseur et un circuit de commutation linéaire sont utilisés à cet effet. Application aux laminoirs.
