Abstract
(EN)
The present invention addresses the problem of providing a highly durable all-weather motor capable of maintaining motor performance in such a way that the degradation of the motor performance is prevented by enhancing a heat dissipation property and the intrusion of foreign objects is prevented by enhancing dust-proof and drip-proof properties. The problem is solved as followed. A rotor (14) has: a rotating case body (4) covering the outer circumferential side of a stator core (12) and both end sides of a bearing housing (11) in the axial direction, having an intake opening portion (4e) on one end side in the axial direction, and having a discharge opening portion (4f) on the other end side in the axial direction, said intake opening portion (4e) taking in air in the axial direction, said discharge opening portion (4f) discharging air in the radial direction; and a fin (17) provided on the inner surface of the rotating case body (4) at the other end in the axial direction. The intake opening portion (4e) and the discharge opening portion (4f) are each covered with a water-shedding filter material (18) having a predetermined opening size.

La présente invention aborde le problème de la fourniture d'un moteur tout-temps très durable capable de maintenir des performances de moteur de telle sorte que la dégradation des performances du moteur est empêchée par l'amélioration d'une propriété de dissipation de chaleur et l'intrusion d'objets étrangers est empêchée par l'amélioration des propriétés anti-poussière et anti-égouttement. La solution de l'invention porte sur ce qui suit. Un rotor (14) comprend : un corps de boîtier rotatif (4) recouvrant le côté circonférentiel externe d'un noyau de stator (12) et les deux côtés d'extrémité d'un boîtier de palier (11) dans la direction axiale, ayant une partie d'ouverture d'admission (4e) sur un côté d'extrémité dans la direction axiale, et ayant une partie d'ouverture de décharge (4f) sur l'autre côté d'extrémité dans la direction axiale, ladite partie d'ouverture d'admission (4e) admettant de l'air dans la direction axiale, ladite partie d'ouverture de décharge (4f) déchargeant de l'air dans la direction radiale ; et une ailette (17) disposée sur la surface interne du corps de boîtier rotatif (4) à l'autre extrémité dans la direction axiale. La partie d'ouverture d'admission (4e) et la partie d'ouverture de décharge (4f) sont chacune recouvertes d'un matériau de filtre de délestage d'eau (18) ayant une taille d'ouverture prédéterminée.
