Title (EN) IMPROVEMENT TO ELECTRIC MOTOR OF THE BRUSHLESS DIRECT CURRENT MOTOR TYPE
(FR) PERFECTIONNEMENT AU MOTEUR ELECTRIQUE DU TYPE MOTEUR A COURANT CONTINU SANS BALAI
Abstract:
(EN) The present invention relates to electric motors of the brushless direct current motor type. The motor is comprised of two coaxial stators (5, 5') with a common magnetic circuit (6) and two concentric rotors (4, 4') mounted on a driving part secured to the motor shaft (1a). The invention applies to synchronous motors and to asynchronous motors.
(FR) La présente invention concerne les moteurs électriques du type moteur à courant continu sans balai. Le moteur comporte deux stators coaxiaux (5, 5') à circuit magnétique (6) commun et deux rotors concentriques (4, 4') montés sur une pièce d'entraînement fixée à l'arbre moteur (1a). L'invention s'applique aux moteurs synchrones et aux moteurs asynchrones.
