1. Belt conveyor power transmission system equipped with two wound-rotor induction motors with start-up resistors, characterised in that it has additional resistor (R3) and battery of condensers (C), which are connected into the circuit of the engine rotor windings (M1, M2) by means of switches (W5, W6), connecting at the same time the windings with each other, while the mains switch (W2) of the engine (M2) is opened and the winding of engine stator (M2) is shorted to the switch (W3) and switches (W7, W8) of the start-up resistors (R1, R2) are opened.<IMAGE>
