Abstract

Ce circuit évite les effets des tensions parasites de courte durée, ménage les contacts des relais et supprime le passage direct du moteur 11 d'un sens de rotation à l'autre par l'utilisation de deux temporisateurs 14 et 15 entre un comparateur 1 de la tension assignée U? et la tension réelle Ul fournie par le transformateur réglable et les organes de commutation 12, 13 pour l'alimentation et l'inversion du moteur 11.This circuit avoids the effects of short-term parasitic voltages, protects the relay contacts and eliminates the direct passage of the motor 11 from one direction of rotation to the other by the use of two timers 14 and 15 between a comparator 1 of the rated voltage U? and the actual voltage Ul supplied by the adjustable transformer and the switching members 12, 13 for supplying and reversing the motor 11.
