Abstract :
This paper presents results on both experimental research and theoretical analysis of data acquisition aspects for vibration fault detection and isolation systems and in particular, for studying the signature of "real" sampled vibration signals in electric drives with unbalanced rotor. It was revealed that the structure of real vibrations of electric drives with unbalanced rotor is a very complicated nonlinear combination of many factors acting together. Finally, the impossibility of adequate vibration diagnosis without taking into account all effects that may alter the vibration (or stator current) power spectrum was discussed
