摘　　要：介绍了几个比较重要的风扇叶参数对电机外风扇性能的影响,并结合后倾式径向离心外风扇物理模型,对其进行流动特性分析,得出外风扇P-Q特性曲线,电机外风路系统的散热能力与该曲线有直接关系,从而为电机外风路设计提供参考。This paper introduces several important influence of fan blade parameters on external fan performance of electric motor,and combines with a physical model of backward-tilting radial centrifugal external fan to analyze flow characteristics of it.The P-Q characteristic curve of the external fan is obtained,which is directly related to the heat dissipation capability of the external wind path system of the motor.It provides some reference for the design of the external wind path of the motor.
