The present invention provides a direct drive typed traction motor for a railway vehicle including a coupling comprised of a carbon fiber. The direct drive typed traction motor for a railway vehicle of the present invention comprises: a stator fixed in a carriage for railway vehicle; a rotor including a permanent magnet and combining with an axle; a frame covering the stator and the rotor; a housing combined with both ends of the frame; and a coupling reducing a vibration generated from the rail by combining with the axle, and having a carbon fiber as a material, so that a weight and initiative may be reduced, a response characteristic is improved, flux path structure is smoothly performed, and heat generation is increased. A stabilized combining structure of a frame structure and a coupling, and reduction in weight of the coupling is very important for preventing accidents and in a good cooling property of the traction motor. Accordingly, the total weight of the traction motor is reduced, and a response speed is improved by comprising the coupling material of the traction motor with the carbon fiber.
본 발명은 대차에 고정되는 고정자; 영구자석을 포함하고 차축과 결합되는 회전자; 상기 고정자와 회전자를 감싸는 프레임; 상기 프레임의 양단에서 결합되는 하우징; 상기 차축과 결합되어 레일로부터 오는 진동을 감소시키고, 중량 감소, 이니셔 감소, 응답 특성 개선, 자로(flux path)구조 원활, 열방출 개선 되도록 탄소섬유를 재료로 하는 커플링; 을 포함하여 구성되는 것을 특징으로 하는 탄소섬유로 구성된 커플링을 포함한 전동차용 직결구동방식 견인전동기를 제공한다. 프레임의 구조와 커플링과의 안정된 결합 형태 구조 및 경량화는 안전사고 방지 및 견인전동기의 냉각 특성에서 매우 중요하고, 이와 관련되어 견인전동기의 커플링의 재료를 탄소섬유로 구성하여 견인전동기 전체의 중량을 감소시키고 또한 응답속도가 개선되는 효과가 있다.
