FIELD: electric rolling stock. SUBSTANCE: proposed traction electric drive contains several groups of traction motors, dc voltage impulse converters, linear contactors and input LC-filter. According to invention, additional circuits consisting of series-connected contactor and diode should be used to be connected between groups of traction motors to provide stepless transfer from one connection of traction motors to the other and additional mode contactors to change mode of operation of drive. Namely, traction or electric regenerative braking. EFFECT: improved tractive properties of electric drive, reduced power consumption. 1 dwg
