Abstract

The two-dimensional (2D) analytical model for the calculation of the components of the flux density distribution in the air gap in a dual-stator axial-field flux-switching permanent magnet (PM) motor (DSAFFSPM) is presented. The novelties of this study are deriving a 2D hybrid analytical model and replacing the rotor teeth with some surface currents for the calculation of air-gap magnetic flux density for the first time in the DSAFFSPM motor. The 2D analytical model for DSAFFSPMs is more challenging due to the doubly salient structure and inner PM of the stator. 1D analytical interior PMs are first transferred to the bore of the stator body using the magnetic equivalent circuit model (MEC). Next, the effects of the rotor teeth are taken into consideration by injecting virtual surface currents for 2D analytical model. Applying boundary conditions and solving the Laplace/Poisson equations, the vertical and tangential flux components of the flux density distribution in the air-gap DSAFFSPM motor are computed. The verification of the proposed method and the obtained results are validated by the 3D finite element method.

双定子轴向磁场磁通开关永磁电机的二维混合分析电磁模型

本文介绍了计算双定子轴向磁通开关永磁（PM）电机（DSAFFSPM）气隙磁通密度分布成分的二维（2D）分析模型。本研究的新颖之处在于首次在 DSAFFSPM 电机中推导出二维混合分析模型，并用一些表面电流代替转子齿来计算气隙磁通密度。由于定子的双突出结构和内部 PM，DSAFFSPM 的二维分析模型更具挑战性。首先使用磁等效电路模型 (MEC) 将一维分析内部 PM 转移到定子机身内孔。然后，在二维分析模型中注入虚拟表面电流，以考虑转子齿的影响。应用边界条件并求解拉普拉斯/泊松方程，计算出了气隙 DSAFFSPM 电机中磁通密度分布的垂直和切向磁通分量。三维有限元法验证了所提方法和所得结果。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
