论文摘要

电气机械芯是由具有高磁性特性的铁磁材料形成的。由于铁磁材料具有较高的相对磁渗透性,因此它们在电磁器件芯的形成中很重要。用于制造电机的常规减法和粉末冶金方法可提供明显的核心损失,并降低磁通量密度和磁渗透性。随着技术的发展,可以使用增材制造过程克服传统过程的局限性。因此,本文提出了两种类型的单相变压器的3D可打印模型,分别称为E-I Shape和U-I Shape Transformers。研究了设计具有铁磁芯的电气机械部分的可能性。根据磁通量密度分布和体积损耗密度,根据comsol的各种操作情况下的大量有限元仿真方法的结果评估了变压器的效率。评估了变压器芯上各种铁磁材料(例如软铁(Fe)和铁氧体(FE2O3)的性能。该分析表明,如果可以由3D打印制成U-I形变压器,则它将是较高工作频率的最佳可行结构。

The electrical machinery core is formed with a ferromagnetic material that offers high magnetic properties. As ferromagnetic materials have high relative magnetic permeability, they are important in the formation of electromagnetic device cores. Conventional subtractive and powder metallurgy methods for fabrication electrical machineries offer significant core losses and reduce magnetic flux density and magnetic permeability. With the advancement of technology, the limitation of the traditional process can be overcome by using the additive manufacturing process. Hence, this paper proposes a 3D printable model of two types of single-phase transformers, referred to as E-I shape and U-I shape transformers respectively. Possibilities of designing the electrical machinery part which has a ferromagnetic core are investigated. The efficiency of the transformers is evaluated in terms of magnetic flux density distribution and volumetric loss density based on the results of a large number of Finite element simulation methods under various operating situations on COMSOL. The performance of various ferromagnetic materials such as Soft Iron (Fe) and Ferrite (Fe2O3) on the transformer core is evaluated. This analysis reveals that if U-I shaped transformer can be made from 3D printing, it will be the best feasible structure for higher operating frequency.
