Abstract

Today, dedicated metal 3D printing platforms can produce industrial grade homo-material metal components, promoting the fabrication of soft magnetic components for electrical machines with three-dimensionally optimized topologies. The printed components have been shown to exhibit excellent DC magnetic properties, indicating the maturity of the technology for applications incorporating quasi-static magnetic fields, such as magnetic couplings or rotors of synchronous machines. In the paper, finite element modeling of a synchronous reluctance magnetic coupling is investigated. Previously 3D printed and researched material of electrical steel with 6.5% added silicon content with selective laser melting is adopted in the model, alongside the printing limitations of the printing system. Commercial finite element modeling software COMSOL Multiphysics is employed for modeling. Printing of the modeled coupling was currently unsuccessful due to unoptimized printing parameters.

轴向同步磁耦合建模与选择性激光熔化打印

如今，专用的金属3D打印平台可以生产工业级同质材料金属部件，促进了具有三维优化拓扑结构的电机软磁部件的制造。打印的组件已被证明具有优异的直流磁性，这表明该技术在结合准静态磁场的应用方面已经成熟，例如同步电机的磁联轴器或转子。本文研究了同步磁阻联轴器的有限元模型。模型采用先前3D打印和研究的电工钢材料，添加6.5%硅含量，选择性激光熔化，同时考虑到打印系统的打印限制。采用商用有限元建模软件COMSOL Multiphysics进行建模。由于未优化打印参数，建模耦合的打印目前不成功。
