摘　　要：针对正在开发的YB3隔爆型三相异步电动机外风路的流场机理进行了研究,采用基于CFD理论的流体仿真分析方法,对YB3电机的典型规格450 6P电机外风路进行了流场仿真分析,突破了复杂结构建模、网格划分等的技术,解决了介质假设、边界条件设置等问题,通过CFX软件的分析、数据处理,揭示了YB3电机外风路的流场机理,并通过对比分析印证该方法的正确性。为YB3电机的研发以及其他高效电机的研发提供了技术保障。As for the YB3 series flameproof three-phase induction motors under develop- ment, flow field mechanism of external wind path is researched. Simulation analysis on flow field of external wind path of typical product （6-pole YB3 motor with frame size 450） is carried out based on CFD theory by fluid simulation analysis method. This method has made a break- through in technologies of complex structure modeling and grid partition and has solved prob- lems of assuming medium and setting boundary condition. This paper reveals flow field mecha- nism of external wind path of YB3 series motors by CFX software analysis and data processing and confirms correctness of the method by contrastive analysis. It provides a technical support for research and development of YB3 series motors and other high-efficiency motors.
