Outline of Final Research Achievements

In recent years, enhanced environmental considerations have led to an increased demand for low-noise three-phase squirrel-cage induction motors (abbr. IMs). Although the basic theory of IMs has been clarified in numerous studies, 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 examine the radial distributions of electromagnetic vibration and noise in an IM under load conditions. As a result, it was experimentally clarified that the peculiarity of the vibration component for the load condition was different from the peculiarity of component at the other measurement point. And the peculiarity of the vibration component in a load condition is differently by the measurement position. We investigated the effect of the measurement position on the vibration component. We show that the vibration component to detailed experimental results.
