The paper deals with the problem of defining the efficiency factor of electric traction machines of locomotives in operating conditions. Due to the fact that most of the time locomotives are operated with underload, for an objective evaluation of the energy efficiency of locomotives, it becomes necessary to take into account the power underutilization of traction electric machines in energy conversion. Based on the methods of electric drive theory, a formula for defining the efficiency factor for traction electric machines operating in a wide range of capacities is developed, which takes into account the influence of changes in operating modes on the efficiency of energy conversion. The analysis results of 2TE25KM diesel locomotive operation data are presented and the dependence of the efficiency factor in accordance with the position of the driver's controller is determined.
