Operation Features of Electric Locomotive Traction Motors of Taishet - Takshimo Northern Direction of the Eastern Polygon of Russian Railways

Abstract

The authors have established the starting up and operation of the electric locomotive of the Eastern Polygon of Russian Railways after long-term holding at a low temperature in winter, with increased power, current and winding temperature due to the transition of bearings from rolling mode to sliding behaviour, with a multiple increase in power, loss of friction in the roller-ring contacts of the bearing cause intensive ageing of insulation. It is proposed to heat up the traction motors during the holding.
