摘要
论文先简要介绍模态分析理论,再运用机电类比的方法推导定子固有频率的计算方法,并用ANSYS软件对电机定子建立的三维有限元模型进行模态分析,计算出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动机的电磁振动和噪声。
The paper introduces the theory of the model analysis. The electromechanical analogy method is used to de rive thc calculation method of the natural frequency of the stator, and the ANSYS software is used to set up motor stator three-dimensional finite element model and model analysis. The natural frequency and vibration mode are calculated to avoid resonance of frequencies and force with electromagnetic force then reduce electromagnetic vibration and noise of PMSM.
