ACTIVE VIBRATION REDUCTION DEVICE AND METHOD USING ELECTRO-MAGNETIC FORCE OF NON-CONTACT MOVING COIL

摘要

The present invention relates to an active mount device, and more specifically, to a non-contact operating coil type active vibration reduction device which can partly absorb external shock and can actively reduce vertically applied vibration through magnetic control of a permanent magnet facing a solenoid coil which generates electromagnetic force and moves by the vibration applied in a vertical direction, to actively reduce the vibration transmitted from a vibration generator (which refers to devices inducing the vibration such as various types of equipment facilities and pumps). According to one embodiment of the present invention, the device can actively absorb the vibration or shock, by rapidly detecting the shock or the vibration transmitted from the vibration generator.
