Title:
自己換気主電動機の中の空気出口のためのモジュラー化された延長リング
Document Type and Number:
Japanese Patent JP2012503461
Kind Code:
A
Abstract:
The invention relates to an elongation ring 3 adapted for use in a self-ventilated traction motor and for fixed placement between the non-driving end of the motor housing 1 and a motor end shield 5. The ring has radial air outlet openings 4 placed along its circumference and thus is adapted to enclose a fan wheel 2 fixed on a motor driving shaft. The invention also relates to a traction motor comprising such an elongation ring. 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.
