FIELD: transport; vehicle traction electric drive. SUBSTANCE: system has at least two induction motors supplied in parallel by common power source. The latter is controlled by control unit which sends to it first control signal which determines supply frequency and second control signal which determines supply voltage amplitude. Control signals are regulated depending on main supply current measurement signal, control signal and signal corresponding to maximum rotor speed. If two induction motors are used, one of them is coupled with two front wheels, and the other, with two rear wheels of vehicle. If four induction motors are used, two of them are coupled with independent front wheels and two others, with independent rear wheels. EFFECT: enlarged operating capabilities. 18 cl, 9 dwg
