| Abstract: | The rotor of motor can easily run eccentrically once the balls of motor stator bearing are broken, which, thus, can easily cause the motor trouble. Using wavelet transform to analyze sound signals of balls can effectively find out the precise corresponding relationship between the sound energy and the size of broken balls, so that any motor trouble can be prevented. |
