Abstract

Titre : Moteur électrique sans balais à membrane de régulation de pression interne La présente invention fournit un moteur électrique sans balais destiné à mettre en rotation une hélice d’un groupe moto-ventilateur d'un véhicule, comprenant au moins deux éléments électromagnétiques, au moins un des éléments électromagnétiques étant équipé d’au moins deux bobines, un boitier (11) délimitant un volume intérieur dans lequel sont logés un circuit d’asservissement et un circuit de puissance (15), le circuit de puissance (15) étant configuré pour relier électriquement une alimentation électrique du véhicule aux bobines. Le circuit de puissance (15) comprend au moins un tube (100) configuré pour mettre en communication aéraulique le volume intérieur du boitier (11) avec un environnement extérieur du boitier (11), le tube (100) traversant une paroi (51) du boitier (11), le circuit de puissance (15) comprenant au moins une membrane respirante (200) agencée pour fermer le tube (100), la membrane respirante (200) étant imperméable à l'eau liquide et perméable à au moins un gaz.
