摘　　要：铁损是评价硅钢片质量好坏的一个重要指标,介绍了一种运用ARM7智能芯片对单片硅钢片铁损进行自动测量的系统,从理论与实际运用两方面探讨了如何在不同磁通密度下对不同厚度和密度的单片硅钢片的铁损测量,并对系统的主要部分进行了介绍,包括励磁机构、电源以及软件设计。实验结果表明,该铁损测试仪器具有成本低、可靠性高、扩充和维护方便等优点,具有一定的推广应用价值。Iron loss is one of the primary quality factors of silicon steel sheet. An automatic measuring system was introduced based on ARM7 for iron loss of silicon steel single sheet. It was described that how to measure the iron loss of silicon steel single sheets whose thickness and density is not same, when the magnetic flux density is different from theory and practice application. The hardware and software designs were introduced. The results demonstrate that the single sheet tester is low cost and high reliability, and it facilitates to be expanded and maintained. It is worth to be widely promoted and applied.
