Abstract
An elongation ring adapted for use in a self-ventilated traction motor and for fixed placement between the non-driving end of the motor housing and a motor end shield. The ring has radial air outlet openings placed along its circumference and is adapted to enclose a fan wheel fixed on a motor driving shaft. A traction motor having such an elongation ring is also contemplated. The elongation ring provides a possibility to easily adapt a motor housing to different motor types such as a self-ventilated motor with the ring, or one with forced ventilation without the ring.
