DEVICE FOR GUIDANCE OF ELECTROMAGNETIC VIBRATORS Russian patent published in 2009 - IPC G05D19/02 

FIELD: physics, guidance.

SUBSTANCE: invention concerns control means and can be used for guidance of vibration amplitude of electromagnetic vibrators. The device contains consistently joined the electromagnetic vibrator with the data unit of velocity of working body, the amplifier, a differentiating link. The integration block, the rectifier, a comparison device, system of the pulsewise-phase guidance, the controllabled rectifier and the bridge inverted rectifier are consistently connected to the amplifier. The threshold device related through drivers with shutters of two transistors of the bridge inverted rectifier in which are consistently joined the first transistor, is connected to the differentiation block the first diode, the second transistor, the second diode, the first transistor. The diagonal of a direct current of the inverted rectifier is joined to the condenser and the controllabled rectifier, and the diagonal is alternating-current joined to the electromagnetic vibrator.

EFFECT: embodying of stabilisation of vibration amplitude in a resonant mode, fuller use of a wattless power of the vibrator.
