Reliability of Electric Locomotive Traction Motors at Eastern Polygon

Abstract

The authors have established the intensive nature of the reducing the reliability of traction electric motors of VL80 and VL85 freight electric locomotives long-term operated on the railways of the Eastern Polygon and 2,3,4ES5K electric locomotives recently received from the manufacturing plant. This makes it possible to identify the weakest units of traction electric motors, the dominant cause for reducing their reliability, and to rationally manage the provision process of their maximum possible failure-free operation.
