摘要 为研究不同数值计算方法在电机三维温度场分析中的应用,以一台11kW、1 500r/min全封闭自扇冷异步起动永磁同步电机为例,分别基于有限元法、有限体积法和有限公式法进行温度场仿真,并在多套剖分网格仿真计算的基础上,对比分析同一网格下应用有限公式法和有限元法的永磁同步电机三维温度场计算结果。同时,分析有限公式法在不同网格数下的计算收敛性。最后,对比有限公式法、有限元法温度场计算结果与有限体积法流固耦合传热计算结果的区别,并以试验值对比验证了仿真计算的准确性。

Abstract:In order to study the application of different numerical methods in the three- dimensional temperature field calculation of electric machines, a 11kW, 1 500r/min totally enclosed fan-ventilated line-start permanent magnet motor was taken as an example. The three-dimensional temperature field was calculated based on finite element method (FEM), finite formulation method (FFM), and finite volume method (FVM), respectively. With the use of multiple sets of meshes, the three-dimensional temperature field of permanent magnet synchronous machine (PMSM) was calculated by both FFM and FEM, and the results were compared with the same grids. Meanwhile, the computing convergence of FFM with different grids was analyzed. Finally, the differences of temperature field calculation results with FFM, FEM and FVM were compared, and the accuracy of the calculation was verified by a temperature rise test.
