Abstract

L'invention porte sur une méthode de commande d'un enrouleur de câbles en commandant la vitesse et le couple en détectant la vitesse et le couple d'un moteur CA à induction à l'aide d'un codeur et d'un ampèremètre, et en comparant la vitesse et le couple détectés à une vitesse et à un couple prédéterminés. Ladite méthode consiste: à fixer une vitesse et un couple de référence nécessaires pour commander le moteur CA à induction tournant dans un sens et dans l'autre pour enrouler le câble autour d'un tambour; à mesurer la vitesse et le couple actuels du moteur CA à induction à l'aide du codeur et de l'ampèremètre; à comparer la vitesse et le couple mesurés avec la vitesse et le couple de référence dans un contrôleur; et à asservir la vitesse et le couple du moteur CA à induction aux résultats comparés dans le contrôleur.
