摘　　要：基于微型厢式货车用驱动电机的运行工况建立其各类损耗的分析模型,结合有限元软件对电机铜耗、铁心损耗、永磁体涡流损耗等进行计算,并进一步得到机壳水冷散热结构下的电机温度分布;计算结果与实验结果较吻合,验证了电机损耗与温升求解过程的准确性。应用智能优化算法对电机电磁与水道结构中的多个参数进行磁热耦合多目标优化,优化后的电机整体模型与初始方案相比,综合性能得到有效提高。Various loss analysis models were established based on the operating condition of the drive motor for microvan.Combined with the established model and finite element software,the motor copper loss,iron core loss and eddy current loss of permanent magnet were calculated,and the temperature distribution of the motor under the structure of shell water cooling could be further obtained.The calculated results were in good agreement with the experimental results,which verified the accuracy of the calculation process of loss and temperature rise.The intelligent optimization algorithm was used to optimize the electromagnetic and waterway structure parameters by adopting the magneto-thermal coupling method.Compared with the initial motor scheme,the overall performance of the motor was improved after optimization.
