ELECTRIC DRIVE Russian patent published in 2010 - IPC H02P27/05 H02P25/00 

FIELD: electricity.

SUBSTANCE: electric drive comprises asynchronous electric motor with phase rotor, three-phase transformer, transistors and diodes. At the same time beginnings of transformer windings are connected to appropriate phases of rotor circuit, and ends are connected to collectors of controlled transistors, parallel to which diodes are connected, between phases of transformer there are normally open contacts of contactors arranged, secondary windings of transformer are connected via rectifier to consumer of electric energy.

EFFECT: maintenance of electric energy quality at required level and electric energy extraction from rotor circuit.
