Abstract: FIELD: electrical engineering; variable-speed ac drives. 
     SUBSTANCE: newly introduced in proposed electric drive is adaptive torque regulator that generates rotor flux linkage vector by shaping phase-by-phase assignment of its instant values whose frequency and amplitude depend on torque assignment. Angle of 45 deg. between stator current and rotor flux linkage vectors optimal from the standpoint of minimizing stator input current is attained by frequency variation. Rotor flux linkage is maintained by introducing phase modifiers whose outputs are connected to control inputs of pulse-width modulation current regulator. Inverter functions to produce stator phase currents at frequency and amplitude required to produce desired torque on condition that stator input current coming from supply mains is minimized and magnetic circuit is used as much as possible. Electric drive operates in real three-phase coordinate system which enables complete elimination of various coordinate conversions complicating calculations and needing mode rigorous requirements to management controller. 
     EFFECT: enhanced power and dynamic characteristics.
