Using the Potentials of Additive Manufacturing on the Field of Electrical Machine Production with Focus on Synchronous Reluctance Machine Rotors

增材制造工艺在不使用成型工具的情况下逐层生产组件和组件。这个过程允许在设计组件的几何形状以及设计材料属性时使用额外的和新的自由度。本研究项目的重点是利用这些新的自由度来改进电机的设计和制造，特别是同步磁阻同步电机的转子。近年来，这种类型的机器作为泵和风扇的节能驱动器获得了新的重要性。为此，特别是使用含6.5%硅的铁硅合金是增材制造的重点。在之前的研究中，在帕德博恩大学直接制造研究中心（DMRC）和汉诺威莱布尼茨大学驱动系统和电力电子研究所（IAL）的紧密合作下，获得了用于增材制造的不同材料系统的基本知识，它们的特性及其在电机中的应用，现在将用于寻找新的方法来更好地设计同步磁阻电机。

Additive manufacturing processes produce components and assemblies layer by layer without using formative tools. This process allows using additional and new degrees of freedom in designing the geometry of the components as well as in designing the material properties.The focus of this research project is using these new degrees of freedom for improving the design and manufacturing of electrical machines, especially of rotors of synchronous reluctance synchronous machines. This machine type has gained new importance in recent years as energy efficient driver of pumps and fans. For this purpose, especially the use of an ferro-silicon alloy with 6,5 % silicon is focused for additive manufacturing.In previous research, fundamental knowledge on different material systems for AM, their characterization and their application in electrical machines were achieved in tight cooperation between the University of Paderborn's Direct Manufacturing Research Center (DMRC) and the Institute for Drive Systems and Power Electronics (IAL) of Leibniz University Hannover, which shall now be used for finding new ways for a preferable design of synchronous reluctance machines.
