Title (EN) LIMITED ANGLE EXTERNAL ROTOR MOTOR ACTUATOR SYSTEM
(FR) SYSTÈME ACTIONNEUR À MOTEUR À ROTOR EXTERNE À ANGLE LIMITÉ
Abstract:
(EN) An actuator system has a external rotor motor (22) having: (i) an internal armature configured as a stator (22) having a set of coils (66) wrapped around a set of arms, and (ii) an external permanent magnet (64) rotor having a set of poles configured to rotate less than 90 degrees around the stator. The actuator system has a drive shaft (26) configured to be rotated by the external rotor motor. The actuator system has a drive train (24) connecting the external permanent magnet rotor (30) to the drive shaft, and configured to provide gear ratio to the drive shaft.
(FR) L'invention porte sur un système actionneur qui comprend un moteur à rotor externe (22) comprenant : (i) un induit interne configuré sous la forme d'un stator (22) comprenant un ensemble de bobines (66) enroulées autour d'un ensemble de bras, et (ii) un rotor à aimant permanent externe (64) comprenant un ensemble de pôles configurés pour tourner à moins de 90 degrés autour du stator. Le système actionneur comprend un arbre d'entraînement (26) configuré pour être fait tourner par le moteur à rotor externe. Le système actionneur comprend une transmission (24) reliant le rotor à aimant permanent externe (30) à l'arbre d'entraînement, et configurée pour conférer un rapport de démultiplication à l'arbre d'entraînement.
