Abstract
Due to the advancement of the electrification of vehicles in automotive industry, there is a growing demand for accurate prediction methodologies for the noise and vibrations generated by electric machine stators. However, it is still difficult to predict such noise and vibration generated by the electric machine stators because the finite element modeling of the structural dynamic characteristics of the motor stators is challenging, because of the complexities caused by the lamination of the electrical steel sheets. In this paper, experimental modal analyses have been conducted on the motor stator and the effects of design parameters such as adhesive layers and bolted joints on the motor vibration and noise are discussed in detail.
