Abstract:In this paper the natural frequencies of the mode shape of vibration of the motor stator, damping characteristics are obtained by making use of experimental model analy sis of a YR-800kW asynchronous motor. and by analysis of measuring results of vibration of core. The result of this paper can be basis in studying and designing large and medium-sized electrical machines for low vibration and noise levels.
Keywords:Vibration Motor Modal analysis Noise
