FIELD: electrical engineering; electric drives minimizing power requirement. SUBSTANCE: electric drive has induction motor connected to voltage regulation unit in the form of thyristor voltage changer with its control system, adder, voltage and power sensors, arithmetic unit, multiplying unit, power and voltage signal differentiating units, and dividing unit. Motor sensors interacting with additionally introduced arithmetic units provide for increasing drive efficiency. EFFECT: improved efficiency under operating conditions of electric drive. 1 dwg
