In bearing fault diagnosis, apart from fault frequencies the modulated frequencies generally happens to appear in the signature. Can any one let me know how to calculate the carrier signal for specific ball bearing configurations. and under what condition of bearing carrier will be present or absent as it affect the analysis process
Dear Satish,
In our opinion, this is not really interesting. It is better to go through demodulations!! Our works are summarized in my IECON 2016 Tutorial.

Thanks Prof Mohamed Benobouzid for proving very useful IECON 2016 paper and presentation . As we are doing research in bearing fault vibration signal analysis, if we know carrier signal then we are able to find fault by blind source separation analysis.
Dear Sir,
Thank you for the IECON paper. It is a great work on the fault analysis and signal processing technique. I have read the paper, but I, have experimented the fault analysis in prognosis tool and it shows the carrier not much affecting the signals, in that case, FFT could trace where as the envelope technique wrongly classify the behavior or the fault. Can you please let me know, how to identify the actual fault frequency of the bearing, if we do not look into the actual mathematical equation that gives the fault frequency depending on the bearing configurations.
