项目摘要
Processing electrical steels to stator and rotor cores of electrical drives results in deteriorated magnetic material properties due to the induced mechanical stresses. Increased electrical losses during operation of the electric motor are the result. Particularly when cutting the electrical steel sheets, the plastic deformation in the area of the cut surface leads to large stresses remaining in the material.In the first phase of the project, the influence of individual shear cutting parameters on the magnetic properties of electrical steels could be demonstrated. However, the effects of individual cutting parameters on the magnetic properties are not independent of one another. They usually influence each other. On the basis of the findings from the first project phase, comprehensive shear cutting strategies must be developed taking into account the requirements for the electrical drive to be produced.Within the framework of the subsequent project it is necessary to secure and expand the findings by means of a further electrical steel alloy with 2.8 wt-% silicon. The analysis of the shear cutting process continues parallel on a numerical as well as on an experimental level. Investigations on electrical steels from the research group-internal and industrial production process ensure the transferability of the results for the industry.Apart from the pure investigation of the magnetic effect of the manufacturing process, the applicability of the results within the development process of electric motors is to be ensured. A consideration of reduced magnetic electromagnetic properties is thereby already possible during the design phase.A comprehensive assurance of the research results is made by means of a demonstrator in the last part of the second phase. It is intended to demonstrate the potential for improving magnetic material properties through the findings of the research group.
将电工钢加工成电气驱动器的定子和转子铁芯,由于诱发的机械应力,导致磁性材料性能恶化。结果就是电动机运行时电损耗增加。特别是在切割电工钢板时,切割表面区域的塑性变形导致材料中留下很大的应力。在项目的第一阶段,可以证明单个剪切参数对电工钢磁性能的影响。然而,各个切削参数对磁性能的影响并不是相互独立的。它们通常相互影响。根据项目第一阶段的研究结果,必须制定综合剪切切割策略,同时考虑到要生产的电气驱动器的要求。在后续项目的框架内,有必要通过进一步使用含有2.8 wt-%硅的电工钢合金来确保和扩展研究结果。剪切过程的分析在数值和实验水平上并行进行。研究小组对电工钢的内部和工业生产过程的调查确保了结果在工业中的可转移性。除了对制造过程的磁效应进行纯粹的研究外,还要保证结果在电动机开发过程中的适用性。因此,在设计阶段就可以考虑降低磁性电磁特性。在第二阶段的最后部分,通过一个实例对研究结果进行了全面的验证。它旨在通过研究小组的发现证明改善磁性材料性能的潜力。
