摘　　要：对IE4高效率三相异步电动机机座的模态进行了分析。以一台22kW电动机为例,建立了IE4高效率三相异步电动机机座三维模型,应用有限元软件进行模态仿真,求解电机机座的固有频率,分析了机座的各阶振型。通过对比,研究了机座底脚、散热筋、以及接线盒对机座固有频率的影响,为机座结构优化提供了依据。This paper gives a model analysis on stator frame of IE4 high-efficiency three-phase induction motor.Taking a 22 kW motor as an example,a 3 D model of the stator frame of the motor was established.The modal simulation is carried out to solve the natural frequencies of stator frame by finite-element software,and the vibration modes with various orders were analyzed.By comparison,the influences of the frame foot,radiation rib and junction box on the natural frequency of the stator frame are studied,which provides a basis for structural optimization of the stator frame.
