A low frequency rolling bearing fault diagnosis method based on local projective noise reduction;

According to characteristics of both the vibration signals and the stator currents when appering a fault in the rolling bearing of the induction motor,Park vector module signal of the three-phase current is calculated,and the envelope of vibration signals from the rolling bearing of the motor is analyzed.

Because the signal from rolling bearing is non-linear and non-Gaussian, here, the bispectrum analysis method is applied to the different types of rolling bearing and the different serious extent for the same bearing fault.
