Abstract
Le dispositif d'entraînement est essentiellement un moteur à champ tournant, utilisant un rotor sans enroulement Chaque phase du stator forme, par adjonction d'une capacité, un circuit oscillant. Un circuit de commande applique une tension continue au circuit oscillant ou le court-circuite suivant une fréquence de commutation correspondant au régime voulu. Pour obtenir la stabilisation de la vitesse du rotor et éviter le pompage on agit, dans une réalisation préférée de l'invention, par une régulation de la tension continue d'entrée de l'unité de commande.The drive device is essentially a rotating field motor, using a rotor without a winding. Each phase of the stator forms, by adding a capacitor, an oscillating circuit. A control circuit applies a direct voltage to the oscillating circuit or short-circuits it at a switching frequency corresponding to the desired speed. In order to obtain stabilization of the speed of the rotor and avoid pumping, one acts, in a preferred embodiment of the invention, by regulating the DC input voltage of the control unit.
