The paper analyses operational indicators of electric locomotives with commutator and induction motor traction motors. It is established that, due to the inherent limitations of the commutator motors, electric locomotives can work with rated power in speed range of 51.2–79 km/h, at maximum speed of 100 km/h power doesn’t exceed 68 % of rated. In order to increase the energy efficiency the authors have proposed to widen by several times the speed range at a constant rated power and reduce as much as possible operation at overload modes. Induction motors have significantly wider ranges for electromagnetic, thermal and mechanical loads. The calculation of losses in converter of phases and frequency for induction motors with various number of phases showed that total losses of three-phase motor reach 1.9 %, losses of motor with even number of phases doesn’t exceed 0.8 %. As a result, it is preferable to use traction motors with 8-phase winding.
