Abstract
In the article the analysis of the existing ways of cooling of traction electrical machines of miner electric locomotives and conditions of their operation in mine working of the mining enterprises was carried out. The known constructive options of traction electric motors of domestic and foreign production are considered, their advantages and disadvantages were revealed. The assessment of system effectiveness of ventilation of the traction DTN-45 electric motor of a mine contact electric locomotive was carried out. The results of laboratory researches on the determination of temperature of heating of elements of the traction engine at natural and compulsory ventilation were presented. The optimum values of pressure and consumption of the cooling air were established.
