Abstract

Moteur à courant continu pour la commande programmée de machines-outils, comportant une carcasse qui contient des aimants reliés à des enroulements d'excitation, et associés à un induit portant un arbre axial rotatif. Ce moteur est pourvu d'enroulements de compensation 9 placés entre les aimants 3 et l'induit, et solidarisés avec les aimants 3. Les enroulements 9 sont placés en série avec des enroulements 12 constituant deux pôles de commutation. Les enroulements 9 empêchent la réaction de l'induit de perturber le flux principal émis par les aimants, et par conséquent de désaimanter ces derniers. De plus, l'invention permet de réduire le diamètre de l'induit et par conséquent son moment d'inertie.
