Air Outlet Hood For Self Ventilated Traction Motors For Rolling Stock

Abstract: The invention relates to an airflow hood for a self-ventilated traction motor (6, 7) mechanically attached to a casing of said traction motor (6, 7) and substantially surrounding a rotatable motor shaft of said traction motor (6, 7), said airflow hood (9) comprising a main body mounted on said casing, and an air duct presenting at one end an airflow inlet and at the other end an airflow outlet (15) downwardly oriented. The airflow hood (9) is located at a proximal end of the traction motor (6, 7) opposed to a shaft prolonging said rotatable motor shaft for driving an axle (3, 4); and the air-flow outlet (15) is arranged asymmetrically with respect to a longitudinal axis of said traction motor (6, 7) on one side of said traction motor (6, 7).
