摘要
开关磁阻电机(SR电机)定子固有频率研究对降低电机的噪声具有重要意义.给出了SR电机定子振动模态分析的数学模型,利用ANSYS有限元软件对二维和三维模型进行计算和分析.结果表明,利用二维模型代替三维模型对定子进行预估计切实可行,可以大大减少工作量,提高计算速度.
It is important to study the stator model frequencies of SRM for reducing acoustic noise and vibration of SRM. The mathematic representation of SR motor＇s vibration mode is described in the paper. Different modes of the 2D and 3D models are completely calculated and analyzed using ANSYS. It is feasible to estimate the stator mode frequencies using 2D instead of 3D model. Thus, the efficiency of calculating could be improved.
