FIELD: electrical engineering.
SUBSTANCE: proposed device for cooling rail traction motor has centrifugal fan designed for rotating in one or two directions; it is disposed in air intake chamber and functions to force air into motor. Air stream forced by fan is bifurcated into inner flow conveyed into confined space accommodating at least motor rotor and external flow passed to air ducts for cooling motor stator. Motor frame has nozzle formed between its inner and outer parts which is separated by means of inner base part from confined space accommodating motor rotor and inner part of its stator.
EFFECT: enhanced cooling efficiency, reduced risk of dirt deposition on motor.
