The IFE electromagnetic drive and the feeder or tube form a vibrating system consisting of two masses. The excitation of the vibration is made by the pumping force of the magnet being connected to the mains via an IFEcontrol unit. The amplitude of the vibration can be adjusted while in operation.
Structural frame bases are used to support mechanical equipment and provide rigid platforms for attachment of vibration isolators, without allowing excessive differential movement between driving and driven members. The bases provide a means by which the equipment can be stabilized and motion reduced by lowering the equipment center of gravity.
