Abstract: Firstly, the electromagnetic vibration of the frequency conversion permanent magnet motor was analyzed and calculated. Then according to the actual electromagnetic vibration vibration waveform of the motor, the optimal damping for vibration isolation was presented by minimization of the mean square value of vibration acceleration response. Finally, simulation proved the effectiveness of the calculated damping to motor vibration isolation.
