Abstract

a. Moteur à courant continu comportant un aimant et des enroulements de commande pour constituer un rotor et un stator ainsi qu'un circuit de commande comprenant un détecteur de position angulaire du rotor et des étages d'amplification. b. Moteur caractérisé en ce que les étages d'amplification réagissent aux signaux de position pour engendrer des courants de commande respectivement proportionnels à sin**2 theta et cos**2 theta ( theta étant l'angle de rotation du rotor), ces courants étant respectivement fournis aux enroulements de commande et le sens de ces courants fournis aux enroulements de commande étant périodiquement inversé. c. L'invention s'applique notamment aux moteurs d'appareils d'enregistrement et/ou de reproduction du son.
