In this paper, it is aimed to design an original axial flux synchronous reluctance motor (AF‐SynRM), which has not been studied in the literature, has multiple barriers in its rotor, and to produce prototype of this motor. In the preliminary study of the AF‐SynRM design, analytical calculations are made on the rotor in two different topologies barrier types, multiple barrier structures, and three different insulation rates. It is modeled with the 3D finite element method (FEM). Torque, torque ripple, saliency ratio, shaft power, and efficiency parameters are analyzed. In the model that gives the best the results analytically, the model is ready for production by changing the barrier geometry with genetic algorithm (GA) based optimization analysis, reducing the torque ripple and completing the structural analysis. The model is made ready for prototype production. Compared to the radial flux model with the same power rating with the proposed design method, 2.2 kW EA‐SynRM prototype with higher torque density and lower volume was produced. The prototype produced has been tested according to the criteria of IEC TS 60034‐30‐2 and has the IEC 60034‐30‐1:2014 IE4 Super Premium efficiency class. Torque, torque ripple, power factor, shaft power, torque per amper, and efficiency parameters are analyzed and compared with simulation results. It will be a good alternative in applications where high efficiency and torque are desired with its lack of copper losses due to the absence of a cage in the rotor and low maintenance costs with its magnet less structure.

新型轴向磁通同步磁阻电动机的最佳转子设计与验证

本文旨在设计一种原始轴向磁通同步磁阻电机(AF‐SynRM),该电机尚未进行过文献研究,其转子中有多个障碍,并生产了该电机的原型。在AF-SynRM设计的初步研究中,对转子进行了两种不同拓扑屏障类型,多种屏障结构和三种不同绝缘率的解析计算。使用3D有限元方法(FEM)对其进行建模。分析了转矩,转矩波动,显着比,轴功率和效率参数。在通过分析得出最佳结果的模型中,可以通过使用基于遗传算法(GA)的优化分析来更改障碍几何形状,减少转矩波动并完成结构分析来准备生产该模型。该模型已准备就绪,可以进行原型生产。与所提出的设计方法具有相同额定功率的径向通量模型相比,生产了具有更高扭矩密度和较小体积的2.2 kW EA-SynRM原型。所生产的原型已按照IEC TS 60034-30-2的标准进行了测试,并具有IEC 60034-30-1:2014 IE4超高级效率等级。分析了转矩,转矩波动,功率因数,轴功率,每安培转矩和效率参数,并将其与仿真结果进行了比较。在需要高效率和高扭矩的应用中,它将是一个很好的替代选择,由于转子中没有保持架,因此由于缺少铜而损失了铜,并且由于缺少磁铁,结构维护成本低。生产了具有更高扭矩密度和更小体积的2 kW EA‐SynRM原型。所生产的原型已按照IEC TS 60034-30-2的标准进行了测试,并具有IEC 60034-30-1:2014 IE4超高级效率等级。分析了转矩,转矩波动,功率因数,轴功率,每安培转矩和效率参数,并将其与仿真结果进行了比较。在需要高效率和高扭矩的应用中,它将是一个很好的替代选择,由于转子中没有保持架,因此由于缺少铜而损失了铜,并且由于缺少磁铁,结构维护成本低。生产了具有更高扭矩密度和更小体积的2 kW EA‐SynRM原型。所生产的原型已按照IEC TS 60034-30-2的标准进行了测试,并具有IEC 60034-30-1:2014 IE4超高级效率等级。分析了转矩,转矩波动,功率因数,轴功率,每安培转矩和效率参数,并将其与仿真结果进行了比较。在需要高效率和高扭矩的应用中,它将是一个很好的替代选择,由于转子中没有保持架,因此由于缺少铜而损失了铜,并且由于缺少磁铁,结构维护成本低。分析功率因数,轴功率,每安培转矩和效率参数,并将其与仿真结果进行比较。在需要高效率和高扭矩的应用中,它将是一个很好的替代选择,由于转子中没有保持架,因此由于缺少铜而损失了铜,并且由于缺少磁铁,结构维护成本低。分析功率因数,轴功率,每安培转矩和效率参数,并将其与仿真结果进行比较。在需要高效率和高扭矩的应用中,它将是一个很好的替代选择,由于转子中没有保持架,因此由于缺少铜而损失了铜,并且由于缺少磁铁,结构维护成本低。
