|発明の名称||VIBRATION SUPPRESSING DEVICE|
PROBLEM TO BE SOLVED: To provide an active vibration suppressing device capable of preventing occurrence of electric power loss steadily by utilizing magnetic force between permanent magnets.
SOLUTION: This vibration suppressing device is composed of the first rotatable permanent magnet 1 formed by making magnetic poles different alternately in the peripheral direction, the second permanent magnet 2 arranged by separating it from the first permanent magnet in the axial direction and polarized in the same manner as the first permanent magnet, and a supporting means 4 for supporting the second permanent magnet 2 so as to move freely in the axial direction and prevent its rotation in the peripheral direction. Rejecting magnetic force and pulling magnetic force acting between the first and second permanent magnets are adjusted by changing rotation angle of an electric motor 3 connected with the first permanent magnet 1, and vibration in the axial direction caused by external force between the first and second permanent magnets is suppressed by magnetic force controlled actively without causing electric power loss for generating magnetic force of an electromagnet by using the permanent magnets.
