IMPROVEMENT OF THE EFFICIENCY OF COOLING OF ELECTRIC TRACTION COMMUTATOR MOTORS WITH AXIAL VENTILATION

POVYSHENIE EFFEKTIVNOSTI OKHLAZHDENIYA KOLLEKTORNYKH TYAGOVYKH ELEKTRODVIGATELEI S AKSIAL'NOI VENTILYATSIEI

On the basis of experimental investigations, the possibility of improving the efficiency of cooling of electric traction commutator motors by changing the direction of the cooling air flow and by using an independent commutator cooling arrangement is demonstrated. At the same time, this permits a reduction in the medium and maximum values of armature overheating, given the same overall flowrate of the cooling air.
