In this paper, the phenomenon of vibration and noise in a small fan motor by electromagnetic force were investigated by 3 dimensional electromagnetic analysis and structural vibration analysis. As a result, it was found out that the significant radiated noise was generated in the axial direction between harmonic frequency of electromagnetic force and natural frequency of the fan.
