: : Dear Sir,
: : I am beginner in fault detection and I have some questions about shaft(rotor) unbalance, & misalignment.
: : What is common method for detection and diagnosis of these fault.
: : I can't understand the meaning of upper harmonic of rotational frequency in the spectrum of rotor.
: : I think we have only one frequency that is the rotational freqeuncy, where do these upper upper harmonic come? and what is the meaning of them?
: : Thanks a lot,
