Abstract

Dispositif de commande d'un moteur sans balais à rotor 10 constitué par un aimant permanent, dont les enroulements statoriques 3, 4 sont montés en série avec des organes électroniques de puissance 5, 6 et dans lequel une bobine il détectrice de la position du rotor, montée sur le stator, commande les organes de puissance par l'intermédiaire d'un oscillateur LC 13. Un élément métallique 12 fixé au rotor 10 et passant devant la bobine détectrice il fait varier l'inductance du circuit LC de l'oscillateur 13 en commandant le fonctionnement ou l'arrêt de celui-ci. Application : moteurs à courant continu sans balais, notamment pour mopour motocompresseur de machines frigorifiques.
