Abstract

LA PRESENTE INVENTION A TRAIT A UN DISPOSITIF D'EXCITATION SANS BROSSES, AUTOREGULATEUR, POUR DES GENERATEURS ELECTRIQUES SYNCHRONES UNIPHASES ET TRIPHASES. LE DISPOSITIF D'EXCITATION SELON LA PRESENTE INVENTION EST CARACTERISE EN CE QUE LE STATOR DE L'EXCITATRICE COMPORTE UN ENROULEMENT AMPEREMETRIQUE RELIE EN SERIE A UN ENROULEMENT CORRESPONDANT DE CHAQUE PHASE DE L'INDUIT DU GENERATEUR; EN OUTRE, IL COMPORTE UN ENROULEMENT D'EXCITATION A VIDE ALIMENTE PAR LA TENSION D'UNE PHASE DU GENERATEUR SUSDIT; L'ENROULEMENT D'EXCITATION A VIDE ETANT TEL QU'IL ENGENDRE UN CHAMP ALTERNATIF FIXE AYANT UN NOMBRE DE COUPLES POLAIRES EGAL A CELUI DU CHAMP TOURNANT ENGENDRE PAR LES ENROULEMENTS AMPEREMETRIQUES DE L'EXCITATRICE. CE DISPOSITIF SERT POUR L'EXCITATION DES GENERATEURS ELECTRIQUES SYNCHRONES UNIPHASES ET TRIPHASES DE PETITE ET MOYENNE PUISSANCE.THE PRESENT INVENTION RELATES TO A BRUSHLESS, SELF-REGULATING EXCITATION DEVICE FOR SINGLE-PHASE AND THREE-PHASE SYNCHRONOUS ELECTRIC GENERATORS. THE EXCITATION DEVICE ACCORDING TO THE PRESENT INVENTION IS CHARACTERIZED IN THAT THE EXCITER STATOR INCLUDES AN AMPEREMETRIC WINDING CONNECTED IN SERIES TO A CORRESPONDING WINDING OF EACH PHASE OF THE GENERATOR'S ARMCHAIR; IN ADDITION, IT CONTAINS A VACUUM EXCITATION WINDING SUPPLIED BY THE VOLTAGE OF A SUSDIT GENERATOR PHASE; THE VACUUM EXCITATION WINDING BEING SUCH AS IT GENERATES A FIXED ALTERNATIVE FIELD HAVING A NUMBER OF POLAR TORQUES EQUAL TO THAT OF THE ROTATING FIELD GENERATED BY THE AMPEREMETRIC WINDINGS OF THE EXCITATOR. THIS DEVICE IS USED FOR THE EXCITATION OF SINGLE-PHASE AND THREE-PHASE SYNCHRONOUS ELECTRIC GENERATORS OF SMALL AND MEDIUM POWER.
