Abstract

A.PETIT MOTEUR A COURANT CONTINU, NOTAMMENT DE PUISSANCE ELEVEE, A AIMANT PERMANENT. B.DANS CE PETIT MOTEUR, LE DIAMETRE DE L'INDUIT, CHOISI OPTIMAL, EST CELUI POUR LEQUEL LE FLUX D'EXCITATION OU LE COUPLE DU MOTEUR EN TANT QUE FONCTION DE CE DIAMETRE, ATTEINT SON MAXIMUM ET IL EST PREVU POUR LE COURANT D'INDUIT UN ELEMENT DE LIMITATION DE COURANT QUI DEPEND DE LA TEMPERATURE, DE LA VITESSE DE ROTATION, DE L'INTENSITE OU DU TEMPS. C.L'INVENTION TROUVE SON APPLICATION PRINCIPALE DANS LES PETITS MOTEURS.A. SMALL DIRECT CURRENT MOTOR, ESPECIALLY HIGH POWER, WITH PERMANENT MAGNET. B. IN THIS SMALL MOTOR, THE DIAMETER OF THE ARMET, CHOSEN OPTIMUM, IS THAT FOR WHICH THE EXCITATION FLOW OR TORQUE OF THE MOTOR, AS A FUNCTION OF THIS DIAMETER, REACHES ITS MAXIMUM AND IT IS PROVIDED FOR CURRENT D 'INDUCES A CURRENT LIMITING ELEMENT WHICH DEPENDS ON TEMPERATURE, ROTATION SPEED, INTENSITY OR TIME. C. THE INVENTION FINDS ITS MAIN APPLICATION IN SMALL ENGINES.
