Abstract:
A traction motor comprises a stator, a rotor core, an iron core holder, a cooling fan, a rotor, a frame, a bracket, and a bearing unit. The cooling fan includes a main plate that separates the inside and the outside of the totally-enclosed traction motor; blades provided on the bracket side of the cooling fan and along a rotational direction of the rotor; and a guide provided on the bracket side of the blades. In the bracket, inlets are provided within an area obtained when the guide is projected onto the bracket. The guide is formed such that air drawn in through the inlets is guided to a rotor shaft.
