摘要/Abstract

摘要： 为了揭示全封闭扇冷式（Total enclosed fan-cooled，TEFC）感应电动机底脚拉筋结构对电动机流场流变特性以及温升分布性能的影响，近而寻求拉筋结构最优化通风冷却性能，以一台TEFC感应电动机为例，在对该电动机进行温升试验测试及温度场数值分析研究的基础上，依据结构特征建立电动机轴向半域流体场以及温度场耦合求解模型，采用有限体积元法对多种拉筋结构方案下的电动机内流体场及温度场进行数值计算。通过对各方案下电动机定子铁心、定子绕组、机壳等部件温升特征以及电动机域内流变特性的比较分析，明确了电动机机壳拉筋对电动机内流体场以及温度场的影响规律，给出了机壳拉筋结构优化方案。

Abstract: In order to reveal the effect of foot tendons structure of the TEFC induction motor on the flow field rheological characteristics and temperature rise distribution performance and obtain the optimal ventilation cooling performance of the foot tendons structure, taking a TEFC induction motor as an example, the fluid field and temperature field coupled solved region of half the motor is established according to the structure characteristics, and the fluid field and thermal field inside the motor with several foot tendons structures are calculated using finite volume element method on the basis of numerical analysis of temperature field and temperature rise test. By comparing of the temperature rise characteristics of stator core, stator winding, frame and so on, and rheological characteristics inside the motor domain under different scheme, the influence of motor foot tendons structure on the fluid field and temperature field is cleared and the optimal scheme of tendons structure is given.

Key words: numerical research, structure optimization, temperature field, total enclosed fan-cooled(TEFC) induction motor, ventilation performance
