Vibration of bearing has been clarified theoretically in previous researches. However, research on vibration modes of the bearing structure mounted on an electric motor has never been conducted. In this paper, radial vibration of the bearing structure mounted on motor is examined by three different methods: a) finite element analysis b) experimental modal analysis under static condition, and c) operation modal analysis. Moreover, researches regarding the vibration effect of a bearing on the bearing structure under different grease condition were also carried out.
