Document Type and Number:
Japanese Patent JP2015050911
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration attenuation apparatus and power storage facility having the same, capable of preventing an apparatus from being destructed due eccentric vibration by effectively attenuating the eccentric vibration when the eccentric vibration occurs at a rotating shaft of a flywheel and preventing kinetic energy accumulated in the flywheel from being wastefully consumed.SOLUTION: The vibration attenuation apparatus includes a rotating magnet 21A rotating together with a rotating shaft M, and a conductor plate 22 which is arranged on vacuum container (stationary member) 11 side, disposed to face the rotating magnet 21A, spaced in the axial direction of the rotating shaft M, the conductor plate 22 generating an eddy current by rotation displaced from the center of the rotating shaft M.
