Abstract
Modal analysis is a technology for vibration characteristic research. It is the foundation for the structural dynamics analysis. Natural frequency is a very important performance in structural dynamics analysis. Modal characteristics of the electric vehicle (EV) driving motor were investigated by finite element method (FEM). FEM models for modal analysis were built for the stator winding, shell, end shield, rotor and shaft by appropriate structure simplification. The influences on natural frequencies of the motor were analyzed. Natural frequencies and mode shapes were simulated by FEM. The accuracy of the FEM analysis is validated by the modal analysis experiment of hammering method and the no-load noise spectrum analysis.
