Abstract: PURPOSE: A device for measuring a dynamic characteristic of a bearing, a system for analyzing the dynamic characteristic, and a method for analyzing the dynamic characteristic of the bearing are provided to predict an unbalanced response and a super-high rotor-bearing system by using the rigidity and a damping coefficient of a bearing. CONSTITUTION: A device for measuring a dynamic characteristic of a bearing comprises a motor housing, a rotor(30), electromagnet(50), and a sensor(40). The motor housing comprises a hollow and stator. The rotor comprises permanent magnetic in which a pure iron core(33) is arranged. The rotor is supported by an airfoil bearing and inserted into the hollow. The electromagnet is arranged in both end parts of the rotor, thereby being formed to excite the rotor. The sensor is formed in order to measure a displacement difference of the rotor caused by excitation.
