Abstract

La présente invention concerne un arrangement électronique pour régler la vitesse d'une machine d'induction. Dans cet arrangement, les impulsions d'allumage Z1R,S,T ou Z2R,S,T des thyristors n1R,S,T et n2R,S,T sont produites de manière à ce que les tensions de sortie du régulateur à courant triphasé 6 forment un système à tension triphasée dont la première harmonique a une fréquence plus faible que la fréquence du réseau d'alimentation. L'invention s'applique notamment aux ascenseurs et monte-charge.The present invention relates to an electronic arrangement for regulating the speed of an induction machine. In this arrangement, the ignition pulses Z1R, S, T or Z2R, S, T of thyristors n1R, S, T and n2R, S, T are produced in such a way that the output voltages of the three-phase current regulator 6 form a three-phase voltage system whose first harmonic has a frequency lower than the frequency of the supply network. The invention applies in particular to elevators and freight elevators.
