摘要
全封闭风冷永磁牵引电动机功率密度高、内部散热条件恶劣,对电机热设计和温升控制提出了较高要求。研究了热网络方法在电机温升分析中的应用,对一款全封闭风冷永磁电机构建热网络模型,并基于MATLAB/SIMULINK平台编程计算热网络参数,实现了对电机内部温升计算和热分析的快速响应。与试验结果对比发现,热网络方法温升计算结果具有较高准确性,能满足电机工程设计需要,对电机热设计具有工程指导意义。
For the high power density and poor heat dissipation condition, much attention was paid on thermal design of air-cooled enclosed PMSM. The application of the thermal network method in the analysis of temperature rise of PMSM was investigated. A thermal network model was presented for a certain PMSM, and its thermal parameters were calculated based on MATLAB/SIMULINK. With the thermal network, rapid calculation of thermal performance of PMSM could be achieved. Compared with experimental results, the thermal network proved higher accurate for design, and had guiding significance to the thermal design of PMSM.
