METHOD FOR SUPPRESSING RADIO-FREQUENCY RADIATION FROM ELECTRIC DRIVE; ELECTRIC DRIVE AND ITS MOTOR Russian patent published in 2000 - IPC

FIELD: electrical engineering. SUBSTANCE: electric drive that has motor and electronic controller with fast-response switching device generating high-frequency energy uses electric screen for taking radio- frequency energy connected via feedback to input of fast-response switching device. Method provides for stepless control of motor output power or torque without heavy loss of electrical energy at low radio- frequency radiation. EFFECT: facilitated suppression of radio-frequency radiation. 22 cl, 19 dwg
