This work objective is to study the thermal conditions of traction electric motors (TEM) of an electric locomotive after factory repairs. Comparison of theoretical and practical methods for defining the temperature of the armature copper of a traction motor after factory repairs. Thermal modes of TEM operation were defined theoretically, using methods of mathematical modelling, and experimentally by the method of IR diagnostics. The scientific novelty of the work lies in the confirmation of the possibility of using mathematical modelling methods when testing traction motors after repairs. The temperature of the armature copper theoretically (by calculation), taking into account the cooling air, was 105 °C, and in practice, when testing traction motors hourly, the temperature was 101 °C. The error between the theoretical and practical methods of diagnosing is less than 4%, which indicates the relevance and possibility of using this method of thermal control during further tests of traction motors.
