CA 2469440

An inside-out ceiling fan motor has a stator mounted to a downrod with an annular array of stator coils positioned about a rotor axis of rotation. A rotor is rotatably mounted about the stator. The rotor has a plurality of vanes spaced along the rotor periphery and canted at an angle of attack to a plane of rotor vanes rotation oriented normally to the rotor axis of rotation to scoop ambient air into the rotor during fan operation through the stator coils to cool them.

Moteur de ventilateur de plafond décroisé qui comporte un stator fixé à une tige inférieure avec un réseau annulaire d'enroulements statoriques placés autour de l'axe de rotation d'un rotor. Un rotor est monté rotatif autour du stator. Le rotor comporte une pluralité d'aubes espacées le long de la périphérie du rotor et penchées à un angle d'attaque par rapport au plan de rotation des aubes du rotor, orientées normalement vers l'axe de rotation du rotor pour envoyer l'air ambient vers le rotor durant le fonctionnement du ventilateur par l'entremise des enroulements statoriques afin de les refroidir.
