摘要
建立了面贴式轴向磁通永磁涡流耦合器的分层解析模型,并且进行了特性分析。通过结合三维等效磁路法、法拉第电磁感应定律和安培环路定理,对轴向磁通永磁涡流耦合器建立了电磁场解析模型。该解析模型能够有效处理模型复杂的几何外形,同时能够考虑三维参数对模型的影响。在解析模型的基础上,讨论了导体层材料、导体层厚度和解析分层数目对解析模型适用性的影响。三维有限元仿真验证表明,建立的分层解析模型在一定范围内有较高的解析精度。
A new analytical framework for the surface - mounted permanent magnet axial flux eddy current coupler is established and the characteristic analysis is carried out. By combining three -dimensional magnetic equivalent circuit approaches, Faraday＇s law and Ampere＇s law, a electromagnetic analysis model of the axial - flux eddy current coupler is established. In addition to account for the three dimensional parameters, the proposed analytical approach can effectively deal with the complex geometric shape of the model. The discussions of the influence of the material and the thickness of the conductor layer on the applicability of the multi - layer analytical model, the influence of the number of layer are carried out based on the analytical model. The results of three - dimensional finite - element simulation show that the established multi - layer analytical model is precise within a certain range.
