FIELD: electricity.
SUBSTANCE: invention relates to alternating current periodic movement drives. Electric drive of oscillating rotary motion consists of two-phase asynchronous motor, excitation winding of which is connected to alternating current source, and control winding to voltage inverter output, voltage-frequency converter, frequency demodulator, precision adjustable direct voltage power supply, phase link and two adders. Output of precision of controlled DC voltage supply unit is connected to first input of first adder, which second input is connected to frequency demodulator output, which input is connected to alternating current source, and output is connected to voltage-frequency converter input. Voltage-frequency converter output is connected to first input of second adder, which second input is connected to phase link output, and output is connected to voltage inverter input. Input of phase link is connected to alternating current source.
EFFECT: control of motion parameters of electric drive vibration-rotation operation mode.
