Abstract

L'invention concerne généralement un circuit de commande d'un équipement électrique à grande puissance, tel qu'un moteur triphasé. Ce circuit comprend un relais R comprenant des seconds contacts R2, R3, R4 pour l'alimentation d'un moteur triphasé M, et des contacts de commande R1 associés à un circuit de maintien 24 pour l'excitation de la bobine Rw du relais, le transformateur 10 d'alimentation du relais comprenant deux enroulement second 21 et 22 pour produire une impulsion de courant important passant dans les contacts R1 pour les nettoyer. L'invention s'applique notamment aux métiers à tisser sans navette.
