Fatigue aging of insulation of traction motors of diesel locomotives

This paper analyzes the problem of occurrence and development fatigue processes in insulation traction motors autonomous locomotives. Factors causing destruction (cracking, delamination, voids) operation have been studied course research. Three characteristic stress cycles (reversible, repetitive, random) were described to make failure predictions. Outcomes investigations temperature conditions windings electric machines diesel locomotives show that during experiences variable thermomechanical stresses. Received data can be recommended take into account creation new for locomotives, as well resource recovery already existing ones.
