Abstract
The article considers the development prospects of the Eastern polygon, indicates the need to increase the service life of the equipment of the operated electric locomotives. The statistics of equipment failures of the Ermak series electric locomotives is presented. It is revealed that the greatest number of failures occurs in the traction electric motor, namely, in its collector-brush device due to the occurrence of an electric arc transfer and insulation breakdown. The reasons for their occurrence are considered. It is proposed to equip traction electric motors with additional sensors, namely: a spark alarm, which will allow timely detection of sparking in the collector-brush device and prevent the formation of a circular fire, and temperature sensors, which will allow direct determination of the winding temperature. The article presents the installation locations of these sensors.
