Radial distribution of electromagnetic vibration and noise on a three-phase squirrel-cage induction motor — Influence of measurement point

In recent years, increasing emphasis on environmental considerations has led to an increased demand for low-noise induction motors (IMs). Although the basic theory of IMs has been clarified in numerous studies [1], the relationship between the radial distribution of electromagnetic vibration and noise and the force wave that causes them has yet to be analyzed in sufficient detail. In this study, we experimentally examined the radial distributions of electromagnetic vibration and noise in an IM under load conditions. In the previous paper [2], it was experimentally clarified that the peculiarity of the vibration component relative to load conditions was different from the peculiarity of the vibration component under other conditions.
