详细介绍了Maxwell软件的铁耗计算模型以及铁耗参数提取计算方法及步骤。采用最小二乘法对硅钢片材料M19_29G的铁损曲线进行拟合分析，得到了可直接输入Maxwell进行计算的铁耗系数。采用Maxwell自带的铁耗参数提取功能验证了计算结果的正确性。为Maxwell软件铁耗系数提取的实现提供了另外一种途径，使得数据处理过程更加开放、灵活，不再受限于软件本身。所述Maxwell软件铁耗参数提取过程对其他商用有限元软件的铁耗系数提取具有重要的参考价值。%The iron loss calculation model of Maxwell software and method and steps of iron loss coefficient extraction were introduced. Iron loss curve of silicon steel sheet material M19_29G fitting was analyzed using the least square method. The iron loss coefficient which could be directly was applied to Maxwell could be obtained. The accuracy of the results was verified by using the Maxwell’s own extracted iron loss coefficient. Provided a new way for the realization of Maxwell software iron loss coefficient extraction, which made the data processing more open and flexible, and was no longer limited by the software itself, and the process of extracting iron loss coefficient for the Maxwell software was an important reference value for other commercial finite element software.
