FIELD: electricity. ^ SUBSTANCE: control device of two-phase asynchronous motor in oscillating flow mode includes alternating current source, master generator, amplitude modulator, two phase links, rectifier, modulator and inverter. Inverter output is connected to control winding of two-phase asynchronous motor the excitation winding of which is connected to alternating current source. The first input of modulator is connected to amplitude modulator output and its second input is connected to rectifier output. Rectifier input is connected to output of the second phase link connected with its input to output of master generator. Phase link is connected with its inputs to alternating current source, and with its output to the first input of amplitude modulator. The second input of amplitude modulator is connected to output of master generator. Modulator output is connected to inverter input. ^ EFFECT: enlarging operating capabilities of the control device of two-phase asynchronous motor due to forming oscillating operating mode of asynchronous motor. ^ 3 dwg |
