Abstract

L'invention concerne un dispositif générateur pour la production d'énergie électrique dans des installations utilisant des sources d'énergie renouvelables. Conformément au préambule de la revendication 1, pour produire une tension indépendante de la vitesse de rotation pour une fréquence réseau fixe, l'invention prévoit que le générateur est muni de deux sections axiales placées sur un arbre et comprenant respectivement un stator et respectivement un rotor et que les rotors comportent des enroulements d'excitation interconnectés de telle manière qu'un champ magnétique rotatif de fréquence Fv peut être appliqué aux stators de sorte que la fréquence de rotation en sortie du stator est indépendante de la vitesse de rotation de l'arbre du rotor.
