Abstract

EN Results of research about influence of mechanical and electromagnetic phenomena on electric motor vibration in different supply options has been shown in this paper. Three different supply options have been taken under consideration: typical star connection, single-phase connection with work capacitor and connection through an inverter. Vibration signals recorded on electric motor end shield and frame has been digitally processed using Multi-Synchronous Averaging (MSA). This technique allowed to decompose total vibration signal into signals associated with mechanical and electromagnetic phenomena occurring in electric motor. The comparison of rms values and spectra shapes of total and decomposed vibration signals has been made. Energy shares of previously mentioned phenomena in vibration signal for different supply options has been also estimated.
