FIELD: transport.
SUBSTANCE: invention relates to mining and aims at perfecting mine electric locomotives. Locomotive traction drive is configured so that one of drive mounted axles is driven by induction motor with wound rotor while another drive mounted axle is driven by induction motor with squirrel-cage rotor. Stator winding of the latter is connected to first motor rotor winding via matching transformer turns ratio equal to that of reducing stator winding to first motor rotor winding.
EFFECT: balanced loads at locomotive mounted axles.
