NVH Prediction of Electric Vehicle Driving Motor Base on Radial Electromagnetic Force Analysis

Article Preview

Abstract:

This paper takes PMSM of EV as research object. Radial electromagnetic force analysis, housing modal analysis and NVH prediction are conducted. Radial electromagnetic force order and frequency are obtained by theoretical calculation, numerical verification is executed using Ansoft software. Modal characteristics are obtained by FEA numerical simulation. Combined the results of the electromagnetic analysis with modal simulation, the NVH performance is investigated.
