Abstract	This paper analyzes the noise and vibration in permanent magnet synchronous motors (PMSM). Electromagnetic forces have been identified as the main cause of noise and vibration in these machines rather than the torque ripple and cogging torque. A procedure for calculating the magnetic forces on the stator teeth based on the 2D finite element (FE) method is presented first. An analytical model is then developed to predict the radial displacement along the stator teeth. The displacement calculations from analytical model are validated with structural FEA and experimental data. Finally, the radial displacement is converted into sound power level. Four different PMSM topologies suitable for electric power steering application are compared for their performances with regards to noise and vibration.
