Abstract

Avec l'enroulement suivant l'invention, lorsque la tension d'alimentation est appliquée aux bornes A8 , B 8 et C8 , l'enroulement est commuté pour être connecté en triangle DELTA et fonctionne avec le nombre de pôles 2p1 = 8 (vitesse inférieure du moteur). Afin d'obtenir un fonctionnement avec le nombre de pôles 2p2 = 6 (vitesse supérieure du moteur), il faut appliquer la tension l'alimentation aux bornes A6 , B6 et C6 , les bornes A8 , B8 , C8 étant courtcircuitées. Dans ce cas, l'enroulement est commuté pour être connecté suivant le schéma en double étoile L'invention peut être utilisée dans les moteurs électriques triphasés à deux vitesses employés en particulier pour la commande des machines-outils à usinage par coupe, ou pour la commande des mécanismes élévateurs.
