中文摘要：

运用机电类比的方法推导了定子固有频率的计算方法,用ANSYS软件对电机定子建立了的三维有限元模型进行了模态分析,计算出了它们的固有频率及其振型,避免和电磁力的频率及次数发生共振,从而降低永磁同步电机的电磁振动和噪声。

英文摘要：

The electromechanical analytical method was used to derive the calculation method of the natural frequency of the stator,and the ANSYS software was used to set up motor stator three-dimensional finite element model and model analysis,calculate the natural frequency and vibration mode,avoid resonance vibration with the frequencies and force wave exponent number of electromagnetic force which could reduce electromagnetic vibration and noise of PMSM.
