Earlier studies have successfully demonstrated the use of the poly-coherent composite bispectrum (pCCB) in the faults identification in rotating machines. However, only amplitudes of the pCCB components were used in the earlier studies. Since the pCCB components are complex numbers (both amplitudes and phases). Hence, the real and imaginary features of the pCCB components are also explored in the fault identification of rotating machines in the current study. The observations from the present study through the experimental rig are presented and compared with the earlier observations using the amplitudes of the pCCB components. It shows that the real and imaginary of the pCCB components shows improvements in fault identification and classification along with a good representation of machine behaviour, compared with the magnitude only of pCCB components.
