摘要:
为了提高定子无铁芯轴向磁场永磁(AFPM)电机中绕组涡流损耗计算的准确性,首先推导了该电机的3D磁场解析模型,并利用3D有限元分析验证了模型的有效性;其次,结合3D解析磁场分析结果,对样机的无铁芯绕组涡流损耗进行了分析计算,不仅考虑了磁密3个方向分量及各方向谐波分量,还对绕组进行了轴向分层,考虑了轴向位置对损耗的影响;最后,对样机进行了实验测定,将基于3D解析磁场计算的无铁芯绕组涡流损耗结果同经验公式及实验测试结果进行了对比分析.结果表明:考虑了3D磁场特性、谐波成分及轴向分层的涡流损耗计算方法大大减少了计算误差,在所研究转速范围内比经验公式计算值均高出34%左右,更接近实际情况.
Abstract:
In order to improve the calculation accuracy of the winding eddy current loss in the stator coreless axial-flux permanent magnet(AFPM)machine, a 3D magnetic field analytical model was derived, and the 3D finite element analysis(FEA)was used to validate the effectiveness of the model. Then, based on the 3D analytical solutions, the coreless winding eddy current loss of the prototype was calculated, considering 3D magnetic field and harmonic components and the influence of axial position on the loss through delaminating the winding axially. Finally, the experiment was performed on the prototype and the analytical results were compared with the experimental results and empirical formula. The results demonstrate that the proposed eddy current loss solution which considers 3D magnetic field, harmonic components and axial position is 34% higher than the empirical formula result in the range of the studied speed and it is closer to the actual situation.
