摘要:
 为了分析电机不同结构下的外风扇的冷却能力并有效优化其冷却能力,以Y2-250M
异步电机原始风扇为例,依据流体力学理论对电机外风扇进行了数值计算和分析,并对不同结构下
的冷却性能进行了详细的分析。研究结果表明,风扇结构的改善可有效减小风扇的风磨损耗,提高
电机的冷却效果,有效提升电机的运行效率,据此完成了外风扇的优化。该研究对风扇扇叶及其结
构优化提供了理论依据,对电机新型通风结构设计方法的探索具有促进效果
Abstract:
 In order to analyse the motor fan cooling capacity under different structures and to optimize its
cooling capacity,aY2-250M asynchronous motor was taken as an example. Not only was the motor external fan’s
fluid fields calculated and analyzed,which was based on the theory of computational fluid dynamic( CFD) ,but also
the cooling capacityof different structures fans were analyzed in detail as well. The results showed that the
improvement of fan structure can reduce fan wind friction loss, improve the cooling effect and operation efficiency of
the motor in effect. We can complete the external fan optimization based on this conclution. This study provides
theoretical basis for fan blades and its structural optimization,and the exploration of design method of motor’s new
ventilation structure is promoted effectively as well.
