摘要
该文以一台物联网车用铁氧体辅助同步磁阻电机(FMaSynRM)为研究对象,以Elmer开源有限元平台为核心,联合运用其他开源软件建立FMaSynRM二维磁场和电路耦合的瞬态有限元模型,重点阐述了其几何建模、网格划分、磁路耦合以及后处理可视化等环节的执行逻辑。在考虑逆变器输出容量限制和主要工作点不同控制逻辑下,对FMaSynRM的铁耗、铜耗、功率因数等主要性能指标进行分析计算,并将计算结果和场图分布与商用有限元分析结果进行对比。最后对样机进行加工和测试,获得其在较宽调速范围内的输出功率图和效率图,并检验其主要性能指标,验证了Elmer在电机电磁场有限元建模计算领域的可靠性和准确性,为其他类型的电机和电磁装置的开源有限元建模提供参考和借鉴。
This paper takes a ferrite magnet assisted synchronous reluctance motor(FMaSynRM)as the study object. To establish the two-dimensional electromagnetic-coupled transient model of this FMaSynRM, this paper selects the open-source platform Elmer as the core solver and cooperates with some other open-source packages. The logic to build the geometry, generate the mesh, tune the electromagnet-coupled setting, conduct the post-processing is emphasized in this paper. With the consideration of the inverter’s capacity, the iron losses, copper losses, power factor etc. at main operating points are evaluated by Elmer and comparisons are made with the commercial software. Finally, the prototype is manufactured and tested. The out-put power and efficiency maps at different speeds are obtained and the results meet the design requirements. The reliability and correctness of the modelling of the FMaSynRM by Elmer is proven, which sets an example for the design of other machines and similar electromagnetic apparatus by the open-source platform.
