FIELD: railway transport. SUBSTANCE: invention relates to electric trains furnished with induction drives. Method of group equalizing of loads of traction induction motors is proposed based on correction of phase currents owing to control of currents in circuits coupling motors operating on common electric shaft. Use of said method provides uniform load of all traction motors (over entire load control range) at their supply with equal voltage of one frequency. EFFECT: simplified power supply. 3 cl, 2 dwg
