An airflow hood for a self-ventilated traction is motor mechanically attached to a casing of the traction motor and substantially surrounds a rotatable motor shaft of the traction motor. The airflow hood includes a main body mounted on the casing, and an air duct presenting at one end an airflow inlet and at the other end an airflow outlet downwardly oriented. The airflow hood is located at a proximal end of the traction motor opposed to a shaft prolonging the rotatable motor shaft for driving an axle. The air-flow outlet is arranged asymmetrically with respect to a longitudinal axis of the traction motor on one side of the traction motor.
