Abstract

La présente invention concerne une commande de moteurs asynchrones. Selon l'invention, on prévoit en avant du moteur uniquement six thyristors 31 à 36 qui peuvent être allumés par paires. Des générateurs d'impulsions 512 à 517 sont synchronisés par paires à partir du réseau par l'intermédiaire de trois connections 518, 519 et 520 suivant les connections R, S et T du réseau triphasé. L'invention permet de doser le freinage et le mouvement ascendant des ascenseurs.
