    In this paper, the noise and vibration characteristics of axial flux permanent magnet synchronous motors were compared and analyzed according to different pole-slot combinations using an electromagnetic-structural coupled analysis. Under load conditions, finite element analysis was performed to evaluate torque ripple and the axial electromagnetic force imbalance acting on the stator tooth surface for each configuration. Modal analysis was then conducted to identify the natural frequencies of the stator. The electromagnetic forces were applied to a coupled electromagnetic-structural simulation to analyze their effects on vibration and noise responses in the frequency domain. Finally, the NVH characteristics of each pole-slot combination were compared using noise levels and waterfall diagrams at various operating speeds.
