Zusammenfassung: | The invention relates to electrical technology. The control device forming the subject of the invention is characterised especially in that it comprises: a memory 10; an analyser 11 for the states of the phase regulators which has its output connected to the control input 12 of the said memory, the outputs of the latter being connected to the inputs of the control block 13 and each phase input of the memory 10 and of the analyser 11 of the states of the phase regulators being linked to the respective output 7, 8, 9 of the phase regulator block 6; a current feedback signal shaper 22 of the third phase conductor. The invention applies especially to the electric motors for advancing parts to be machined on machine tools.
L'INVENTION CONCERNE L'ELECTROTECHNIQUE.LE DISPOSITIF DE COMMANDE FAISANT L'OBJET DE L'INVENTION EST CARACTERISE NOTAMMENT EN CE QU'IL COMPREND: UNE MEMOIRE 10; UN ANALYSEUR 11 DES ETATS DES REGULATEURS DE PHASE QUI A SA SORTIE RACCORDEE A L'ENTREE DE COMMANDE 12 DE LADITE MEMOIRE, LES SORTIES DE CELLE-CI ETANT RACCORDEES AUX ENTREES DU BLOC DE COMMANDE 13 ET CHAQUE ENTREE DE PHASE DE LA MEMOIRE 10 ET DE L'ANALYSEUR 11 D'ETATS DES REGULATEURS DE PHASE ETANT RELIEE A LA SORTIE RESPECTIVE 7, 8, 9 DU BLOC 6 DE REGULATEURS DE PHASE; UN FORMATEUR 22 DE SIGNAL DE REACTION EN COURANT DU TROISIEME CONDUCTEUR DE PHASE.L'INVENTION S'APPLIQUE NOTAMMENT AUX MOTEURS ELECTRIQUES D'AVANCE DES PIECES A USINER SUR LES MACHINES-OUTILS. |
