ROTOR DAMPER USING MAGNET

摘要

A damper using a magnet according to the present invention is a rotor damper comprising a rotary shaft; a rolling bearing part for supporting the rotary shaft; a retainer for covering the rolling bearing part; an inner wheel joined to the outer circumference of the retainer; a housing for covering the retainer at a distance; an outer wheel joined to the inner circumference of the housing to face the inner wheel; and a centering spring for making the retainer supported in the housing. The damper using a magnet includes a permanent magnet joined to the inner wheel; and an electromagnet joined to the outer wheel to face the permanent magnet, thereby reducing the vibration of the rotary shaft using the interaction of the magnetic force between the permanent magnet and the electromagnet.
