摘　　要：电机温升对电机的性能有重要影响,是电机设计的关键。基于流体动力学原理,对矿用防爆电机的热流耦合场进行数值计算,得到了电机内部流场特性、电机整体温度分布、电机各部件峰值温度及所在位置。通过方案比较,确定定、转子铁心长度;然后进行结构优化,采用电机内置风扇、定转子铁心增设通风孔两种方法增强电机内部冷却效果,并验证数值计算的可行性。所得结论为电机设计提供了一定的理论参考。It was the key of motor design because that the motor temperature rise has a significant effect on performance of the electric motors. Thermal-fluid coupled field of mine explosion-proof motor was numerically calculated based on computational fluid dynamics principles. Characteristic of flow field inside the motor, the overall temperature distribution of motor, peak temperature and peak temperature location of motor parts were obtained. Firstly, determine the length of the stator and rotor core by the comparison of proposals. Secondly, optimize the structure according to the temperature distribution, and the motor cooling effect was improved by the method of installing the fan inside the motor and adding vents to the core of stator and rotor. Finally, verify the feasibility of the numerical calculation. The conclusion would provide theoretical references for motor design.
