CONTROL DEVICE OF TWO-PHASE ASYNCHRONOUS MOTOR IN OSCILLATING FLOW MODE Russian patent published in 2016 - IPC H02P23/04 H02P23/00 

FIELD: electronic equipment.

SUBSTANCE: invention relates to electrical engineering, namely to oscillating alternating current drives. Control device of two-phase asynchronous motor in intermittent mode of motion consists of alternating current source, master generator, amplitude modulator, phase link, phase detector, electronic switch and inverter, which output is connected to control winding of two-phase asynchronous motor. Excitation winding of two-phase asynchronous motor is connected to alternating current source. Output of master oscillator is connected to first input of amplitude modulator, second input is connected to output of phase link. Input of phase link is connected to alternating current source. First input of electronic switch is connected to output of amplitude modulator, and by second input electronic switch is connected to output of phase detector. First input of phase detector is connected to phase link output, and second input is connected to output of master generator. Output of electronic switch is connected to voltage inverter input.

EFFECT: elimination of network frequency and master oscillator high-frequency pulsations during formation of oscillating flow of two-phase asynchronous motor.
