Abstract
Moteur à courant alternatif à vitesse variable, comprenant un moteur principal et un dispositif de commande de vitesse comportant plusieurs balais et un collecteur fixe sur lequel frottent les balais par l'intermédiaire duquel le courant arrive aux enroulements fixes du moteur principaL Un tel moteur est caractérisé en ce que les balais sont sollicités élastiquement contre la surface périphérique intérieure du collecteur fixe en étant soumis dune part à la force élastique de ressorts, et d'autre part à la force centrifuge. Principales applications : commande de la vitesse de moteurs à induction.
