Traction motor capable of reducing noise

The utility model belongs to the field of traction motors, and particularly relates to a traction motor capable of reducing noise, which comprises a noise reduction shell, a through groove is formed in the top of the noise reduction shell, sound absorption cotton is arranged in the middle of the inner walls of the four sides of the noise reduction shell, and a rotating hole is formed in one side of the noise reduction shell. The noise reduction device is reasonable in design, the traction motor can be placed in the noise reduction shell and matched with the sound absorption cotton for auxiliary use, compared with a normally used traction motor, the noise decibel generated when the traction motor works is greatly reduced, a production mold of the motor does not need to be changed, and the noise reduction device is suitable for formed motor models, convenient to use and high in practicability. And through cooperative use of a cooling fan, a rotating hole and a noise reduction shell with a large size, heat gener
