The fixed magnetic body of the vibrator, supplied with a 230V AC alternating current, generates an alternating attraction at 50 Hz on the block opposite which is fixed on the machine to vibrate. This special magnetic block will be positioned at a distance from the vibrator thus forming a working air gap. Ensure that there is no mechanical contact between the vibrator and the magnetic block during operation to avoid shocks. The amplitude of the movement is adjusted using the VF6 voltage variator.
