Abstract: A dynamic vibration absorber needs to be designed so that the natural frequency of the dynamic vibration absorber alone becomes equal to the natural frequency of a stator. If these natural frequencies greatly deviate from each other, the effect is reduced. Therefore, the natural frequency of the dynamic vibration absorber alone needs to be accurately calculated to make designing. However, in actual, the natural frequency is greatly influenced by the rigidity around the mounting position of a vibration damping target, and thus there is a problem that the natural frequency becomes different from the designed value upon mounting. An object of the present invention is to reduce an influence on the natural frequency of the dynamic vibration absorber alone given by the rigidity around the mounting position, by mounting a plurality of dynamic vibration absorbers to a dynamic vibration absorber mounting member, thereby making the dynamic vibration absorber more effective.
