Abstract

Dispositif de commande pour moteur asynchrone triphasé, alimenté par une source réglable de tension continue, comprenant un générateur de frequence déterminant la vitesse de rotation, un générateur de signal d'amorçage relié, par l'intermédiaire de circuits de commande, à des éléments de circuit d'un convertisseur, montés en série, par paires, dans au moins trois branches, et un générateur de signal d'extinction, ainsi qu'un circuit d'inversion agissant sur le sens de rotation pour la permutation des circuits de commande des éléments de circuit du converstisseur d'au moins deux branches. Un dispositif de blocage 43 est associé au circuit d'inversion 30, lequel dispositif de blocage empêche l'inversion de marche amorcée, la fréquence du générateur 9 étant transmis proportionnellement à la tension continue régulée U1. Applications : appareillage de commande et de régulation, notamment des moteurs électriques.Control device for a three-phase asynchronous motor, supplied by an adjustable DC voltage source, comprising a frequency generator determining the speed of rotation, a starting signal generator connected, through control circuits, to control elements. circuit of a converter, connected in series, in pairs, in at least three branches, and an extinction signal generator, as well as an inversion circuit acting on the direction of rotation for the permutation of the control circuits of the circuit elements of the converstor of at least two branches. A blocking device 43 is associated with the reversing circuit 30, which blocking device prevents the initiated reversal of operation, the frequency of the generator 9 being transmitted in proportion to the regulated direct voltage U1. Applications: control and regulation equipment, in particular electric motors.
