Abstract

La réalisation d'un moteur de petites dimensions mais à puissance de sortie élevée requiert une grande efficacité de refroidissement. A cet effet, dans un moteur dont le carter est divisé en trois parties, à savoir une partie latérale avant (14), une partie centrale (18) et une partie latérale arrière (16), un séparateur en résine en feuille (26) est disposé sur la surface interne d'un noyau de stator (20) solidaire du carter central (18), et des organes d'étanchéité (30) sont serrés entre les deux extrémités étendues dudit séparateur et des saillies annulaires (14a, 16a) des carters avant et arrière (14, 16), de sorte que la partie d'enroulement de stator est rendue étanche et l'enroulement de stator (40) est refroidi directement par un fluide.
