Abstract

Ce moteur synchrone est du type de ceux comprenant, un rotor avec un enroulement en cage d'écureuil, constitué par un arbre plein et des paquets de tôles maintenant les barres de la cage, des pôles conséquents du rotor étant disposés dans des plans axialement espacés, un stator avec un enroulement de champ et un enroulement d'excitation à courant continu disposé sur le rotor entre les plans précités. Dans le moteur selon l'invention, les paquets de tôles 27 forment des bagues fermées et l'arbre du rotor présente des évidements locaux pour former des pôles 21, 22. Dans un tel moteur il n'y a pas de difficultés pour atteindre l'état synchrone au démarrage.This synchronous motor is of the type comprising a rotor with a squirrel-cage winding, consisting of a solid shaft and bundles of sheets holding the bars of the cage, the consequent poles of the rotor being arranged in axially spaced planes , a stator with a field winding and a direct current excitation winding disposed on the rotor between the aforementioned planes. In the motor according to the invention, the packets of sheets 27 form closed rings and the rotor shaft has local recesses to form poles 21, 22. In such a motor there is no difficulty in reaching the shaft. 'synchronous state at startup.
