A traction motor module of the present invention includes: a fixed shaft; a traction motor including a housing including a first housing combined with the fixed shaft and a second housing of a tube shape combined with the first housing, a stator fixed to an inner wall of the second housing, a rotary shaft which is arranged in a space formed by the stator and protrudes from the second housing, and a rotor including a magnet arranged between the stator and the rotary shaft; and a hub unit which surrounds the traction motor by a tube shape, and is rotated by receiving power from the rotary shaft. The first housing includes a first through-hole formed at the center of the first housing and a second through-hole which is arranged around the first through-hole and has a passage connected to the first through-hole. A coil fixing part to fix a coil wound around the stator is formed in the connection passage. |
