Abstract

L'invention concerne un servomoteur, comprenant un corps de moteur et une broche (11), la broche (11) étant pourvue d'un dispositif de dissipation de chaleur. Le dispositif de dissipation de chaleur comprend une bague de conduction de chaleur (31) emmanchée sur la broche, une surface externe de la bague de conduction de chaleur ayant une pluralité de groupes d'aubes de ventilateur de refroidissement s'étendant vers l'extérieur à partir de celle-ci, et chacun des groupes d'aubes de ventilateur de refroidissement comprenant deux ailettes de refroidissement (33) disposées en parallèle. Le dispositif de dissipation de chaleur comprend en outre un couvercle de dissipation de chaleur (21) en forme de disque, un trou d'arbre étant disposé dans le couvercle de dissipation de chaleur. La broche passe à travers le trou d'arbre du couvercle de dissipation de chaleur. Une pluralité d'entrées d'air (32) sont disposées sur une surface arrière du couvercle de dissipation de chaleur, et un tuyau d'admission (23) est installé sur l'entrée d'air. La surface arrière du couvercle de dissipation de chaleur est fixée à une surface supérieure du moteur par l'intermédiaire d'une tige de liaison (24). Le refroidissement d'air dissipe efficacement la chaleur de la broche et abaisse la température. La structure à double ailette conçue de manière unique élimine rapidement la chaleur, tout en réduisant également le coefficient de traînée de la broche, et en réduisant la perte d'énergie.
