Abstract

A dynamic characteristic measurement device of the present invention includes magnetic force generators () arranged on the back surface side of impellers (), the magnetic force generators that oscillate the impellers () with magnetic force, an oscillation controller () that drives these magnetic force generators, and vibration sensors () that detect vibration of a rotation shaft (). The dynamic characteristic measurement device further includes an arithmetic device () that calculates a dynamic characteristic of a rotor () by implementing a frequency analysis and a mode analysis based on an oscillation signal from the oscillation controller () and a vibration signal from the vibration sensors ().
