摘要:
为了研究隐极同步电动机配套用无刷励磁机的通风方案中冷却空气的流动路径及冷却特 点,依据流体动力学原理理论,采用有限体积法,建立了某新型无刷励磁机相对地面结构的 1 /2 为 物理模型,研究了无刷励磁机通风冷却方案的流动路径、流场和温度场,并给出了通风方案的冷却 特点及流场和温度场的分布特点。计算结果表明,该励磁机方案的最高温度位置出现在靠近整流 盘侧的转子线棒端部,绝缘均不超温。与某电机研究所采用等效风路法所得该方案相同工况下计 算值相比,该通风方案数值模拟进风量误差为 5. 6% ,为进一步优化该励磁机冷却风路系统提供了 理论依据。
Abstract:
In order to study the flow path and cooling characteristic of cooling air of ventilation scheme for the brushless exciter of non-salient pole synchronous motor,the finite volume method was adopted,ac-cording to the computational fluid dynamics ( CFD) principles. A half physical model of a new brushless exciter structure that is relative to the ground was established. The flow path,flow and temperature fields of ventilation scheme of the brushless exciter were researched. The cooling characteristic of ventilation scheme and distribution feature of flow and temperature fields were given. The results show that the posi-tion of the highest temperature of the brushless exciter appear in the end of rotor bar. And the insulation temperature of brushless exciter is not overheating. Compared with the value that is calculated by the in-stitute of electronic machinery technology through Equivalent Network Method,the errors of total volume flow rate is only 5. 6% ,under the same condition. The results provide theoretical basis for further optimi-zing the air ducts structure of the exciter.
