摘要：采用计算流体动力学的方法对YX3小型电机外冷却系统进行了数值计算。分析了冷却风扇的叶片数、叶片外径和叶片宽度对电机风扇通风性能的影响,并从降低风扇输入功率的角度对风扇进行改进设计和样机试验验证。结果表明,装有改进风扇的电机机械损耗下降了39.1%,温升基本不变,电机效率提高了0.6%。
The numerical calculation of YX3 small motor external cooling system was carried out by using computational fluid dynamics method. The influence of blade main structure parameters on the ventilation performance of external cooling fan of small motor was analyzed. From the perspective of reducing the input power of the fan,the fan structure was improved and experimentally verified. The result showed that mechanical loss of the motor with improved fan was reduced by 39.1%,the temperature didn＇t change basically and the efficiency was increased by 0.6%.
