Abstract
In this paper, a finite element (FE) simulation process for the NVH prediction of electric motors is proposed. The proposed process first simulates the motor excitation forces using a 2D electromagnetic force model which is derived from Maxwell and then it applies these forces to a simplified 3D electric machine model. This simplified 3D model is validated by comparing the structural transfer functions calculated from impact hammer test and FE simulation. Finally, the proposed simulation process is validated by comparing predicted sound pressure levels at different selected locations to an electric motor NVH test results from a semi-anechoic chamber.
