VALVE ELECTRIC DRIVE WITH VIBRATING MOTION Russian patent published in 2019 - IPC H02P25/32 H02P25/89 H02P27/48 H02P7/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used in electric drives for scanning, calibrating, measuring, monitoring and controlling, as well as in automated electric drives of mechanisms with oscillatory movement of the working member. Valve motor oscillating motion contains a valve motor with two windings on the stator, the master generator, a rectifier connected by its output to a low-frequency filter input; a voltage inverter whose output is connected to the second stator motor winding. First stator winding of a valve motor is connected to the output of a voltage converter, the input of which is connected to the output of a function converter, the first input of which is connected to the output of a low-frequency filter, and the second – to the output of the frequency demodulator. Inputs of the frequency demodulator, rectifier and voltage inverter are connected to the output of the master oscillator.

EFFECT: improving the energy performance of a valve-driven oscillatory motion due to the formation of an oscillatory mode of operation with adjustable output motion parameters and maintaining a resonant mode of operation when adjusting the oscillation frequency by adjusting its own positional moment.
