VALVE ELECTRIC DRIVE OF OSCILLATORY MOTION Russian patent published in 2017 - IPC H02K33/04 H02P25/02 

FIELD: electricity.

SUBSTANCE: valve electric drive of oscillatory motion comprises the two-phase motor, the alternating current source and the voltage inverter, the outlet of which is connected to the one motor stator winding. The other stator winding of the ac electronic motor is connected to the outlet of the low frequency filter, which is linked with its inlet to the outlet of the rectifier, the inlet of which is connected to the alternating current source. The voltage inverter inlet is connected to the outlet of the phase shifter, the first inlet of which is linked to the drive oscillator outlet, and the second inlet - to the summation unit outlet. The first summation unit inlet is connected to the function generator outlet. The second summation unit inlet is connected to the neutral shift controller. The function generator inlet is connected to the outlet of the frequency-to-voltage converter, the inlet of which is connected to the drive oscillator outlet. The functional capacity enhancement is achieved by means of the oscillation neutral position control within the predetermined frequency range of the oscillations, and its energy performance improvement - by using the ac electronic motor in the function of the actuating machine in the ac electronic motor electric drive.

EFFECT: oscillatory motion electric drive functional capacity enhancement and its energy performance improvement.
