Abstract

Le moteur selon l'invention est du type à stator à aimantation permanente et à rotor formé en matériau magnétique doux. Selon l'invention, ce rotor est formé d'un disque transversal à l'arbre et disposé en regard de la face magnétisée du stator, et circonférentiellement divisé en plusieurs dents polaires par des moyens à haute réluctance magnétique séparant magnétiquement les dents les unes des autres pour magnétiser simultanément les dents adjacentes en polarités opposées alternant en fonction du champ magnétique produit par la bobine Un tel moteur peut être miniaturisé tout en présentant un bon rendement de sortie et une bonne réponse en fréquence
