TORQUE-CONTROLLED INDUCTION DRIVE Russian patent published in 2002 - IPC

FIELD: electrical engineering; frequency-torque controlled drives for industry, transport, and electromechanical equipment. SUBSTANCE: electric drive has electromechanical induction converter 1 with stator phase leads 2, 3 and squirrel-cage rotor 4, speed transducer , first and second adders 6, 7, first functional synchro converter 8, second functional converter 9, first, second, and third multipliers 10, 11, 12, integrator 13, polarity identifier 14, root extractor 15, and current amplifiers 16, 17. Inputs of units 14, 15 and third input of adder 6 whereto desired torque signal is applied function as electric drive input. Novelty is introduction of second adder 7 and connection of third input of adder 6 to drive input. EFFECT: enhanced dynamic characteristics. 5 dwg
