FIELD: electricity.
SUBSTANCE: torque asynchronous electric drive comprises an asynchronous motor (1) with a three-phase stator winding (2-4) and a short-circuited rotor (5), a sensor of rotation frequency (6), the first - third functional converters (7-9), an integrator (10), a summator (11), the first - third multipliers (12-14), the first - third current amplifiers (15-17). The inlet of the electric drive is the first inlets of the second and third functional converters (8), (9).
EFFECT: improved energy efficiency of electric drive operation due to taking into account of magnetic conductor saturation and losses in steel of asynchronous motor stator and rotor.
