The present invention relates to a totally-enclosed traction motor for a railway vehicle and, specifically, to a totally-enclosed traction motor for a railway vehicle having a workability improvement function, which comprises a rotor support device between a bearing housing and a rotor to disassemble and assemble only the bearing, thereby performing quick and smooth maintenance. The totally-enclosed traction motor for a railway vehicle comprises the rotor support device including a fixed frame and a moving frame therein, wherein the fixed frame is formed in a circular band form to be smoothly inserted and tightly coupled to an outer periphery of the cylindrical rotor, and an inner stepped unit is formed on the inside to prevent jamming and to form a supporting force when being coupled with the stepped unit of the rotor.

    본 발명은 철도차량용 전폐형 견인 전동기에 관한 것으로서, 특히 베어링 하우징과 회전자 사이에 회전자 지지장치를 구비하여 베어링만 분해 및 조립 가능토로 함으로써, 신속하고 원활한 유지보수를 이루어 작업성 향상 기능을 갖는 철도차량용 전폐형 견인 전동기에 관한 것이다. 구성은 내부에 고정 프레임과 이동 프레임으로 이루어지는 회전자 지지장치를 구비하는 철도차량용 전폐형 견인 전동기에 있어서, 상기 고정 프레임은 원기둥형의 회전자 외주로 원활한 삽입과 긴밀한 결합을 이루도록 원형 밴드(Circular band) 형상으로 이루어지고, 내측에 회전자의 단차부와 결합시 밀림을 방지하고 지지력을 형성하도록 내부 단차부가 형성되는 것을 특징으로 한다.
