摘　　要：电机的振动噪声和电机结构参数密切相关,为避免电机定子的共振,在设计阶段对电机定子进行模态分析具有重要意义。论文考虑了机座对电机定子振动固有频率的影响,给出了计算定子与机座耦合系统的固有频率的解析计算法,并通过ANSYS有限元方法进行了验证,结果证实两者能够很好的吻合。The motor noise and vibration had closed relevance to the structural parameters, to avoid the stator resonance, it is important to made mode analysis for the stator during the design period, the influences of the stator rind on the stator vibration is taken into consideration, a method for calculating the natural frequencies of the stator and stator rind coupling system is presented, and also calculates by simulation with ANSYS 3D FE software, which verifies that the results have a good consistency.
