摘　　要：文章对某400 kW三相异步感应电机的设计开发经验进行了总结,针对初始电磁方案试验结果不符合设计要求的情况,经理论分析和电磁仿真分析,得出初始方案不合格的原因是轴向通风孔的尺寸太小。通过增大轴向通风孔的尺寸,有效改善了电机的功率因数,最终形成了满足要求的电磁方案。The design and development experience of a 400 kW three-phase asynchronous induction motor is summarized in the paper.In response to the situation that the test results of the initial electromagnetic scheme does not meet the design requirements,it is found that failure of the initial scheme is due to the too small size of the axial ventilation holes after theoretical analysis and electromagnetic simulation.By increasing the size of the axial ventilation holes,the power factor of the motor is effectively improved,and finally an electromagnetic scheme that meets the requirements is formed.
