Title (EN) UNIVERSAL ELECTRIC MOTOR COWL
(FR) BOBINE DE MOTEUR ELECTRIQUE UNIVERSELLE
Abstract:
(EN) A cowl assembly (10) has a cylindrical housing (11) so tapered from base flange (14) to cap extension (18) for moulding purposes housing (11) provided with rectangular sections of opposed channels (12), an annular flange (15) extends about the outer end of the housing (11) whereby cap extension (16) may accommodate a motor cooling fan. The cap extension and the end wall (18) has a central aperture (19) therein providing high volume airflow from motor fan with a base mounting flange so arranged as to extend about the part circular base and the channels of a sealable shape. Airflow apertures (21) in housing (11) adjacent to the base flange and opposed manifolds (22) extend from these apertures. Manifolds (22) expand toward outlet ports (23) which are coplanar.
(FR) Un ensemble bobine (10) comporte un boîtier cylindrique (11) conique depuis le rebord de base (14) jusqu'à un couvercle ajouté (18), ce qui permet le moulage dudit boîtier (11), de sorte qu'il présente des sections rectangulaires de canaux opposés (12) ainsi qu'un rebord annulaire (15) qui s'étend autour de l'extrémité extérieure dudit boîtier (11). Le couvercle ajouté (16) peut recevoir un ventilateur de moteur. La paroi d'extrémité (18) du couvercle ajouté présente une ouverture centrale (19) permettant une entrée d'air importante en provenance du ventilateur, la bride de support de base étant conçue, de sorte qu'elle s'étende autour de la base circulaire et les canaux pouvant être fermés de manière hermétique. Des ouvertures de circulation d'air (21) sont prévues dans le boîtier (11), en position adjacente au rebord de base, et des collecteurs opposés (22) s'étendent depuis lesdites ouvertures. Des collecteurs (22) s'étendent jusqu'aux orifices de sortie (23), qui sont coplanaires.
