Comparison of vibration and noise measurement of induction machine under static eccentricity

Abstract

The paper is focused on the comparison of vibration and emitted noise measurement of induction machine under static eccentricity in an environment with steady acoustic noise producing facilities. Such an environment can introduce for example simple industrial drive stand operating under constant load in a closed room. The analyses are focused to the frequency spectrum up to 1500 Hz which allows us to validate the frequency spectrum of emitted noise by vibration measurement. The analyzed frequency band is sufficient considering vibration response of implemented fault. The analyses of healthy machine are carried on as well to get the reference point.
