Abstract

According to results of analysis of main reasons that lead to failures and unscheduled repairs of electric traction motors of 2ES6 «Sinara» electric locomotives the authors have developed an algorithm of predictive diagnostics for detecting electric damage of stabilizing, armature and exciting windings. They have also established that at functional test and search of electric damage of windings of various traction motors used on locomotives it is necessary to pay attention to armature current deviations between neighbour bogies.
