Summary: | FIELD: locomotive manufacture. SUBSTANCE: frequency-controlled electric drive is provided with at least two bow windings of motor stator connected to separate self-contained inverters of static frequency converter. Currents flowing in self-contained inverters are shifted from each other through angle depending on number of bow windings. EFFECT: enhanced reliability of drive due to reduced load currents in power circuit. 3 dwg |
