| 摘 要： | 旋转磁心损耗广泛存在于高频变压器T形连接点处与高速电机的定子上。为了对二者进行更好的分析,需要将高频下的旋转磁心损耗进行精确测量。本文就四种不同的励磁结构进行有限元分析,阐述了励磁结构对准确度的影响。在此基础上,根据超微晶物理特性提出一种立体式二维高频励磁装置,对励磁绕组进行计算,并优化设计了磁轭结构,将测试频率提高到10k Hz。

Design and Optimization of a Magnetizer for High Frequency Rotational Magnetic Characterization for Nanocrystalline Alloy |

| Abstract: | Rotational core loss is widely distributed in the T-joint of high frequency transformer and the stator of high speed motor. In order to have a better understanding of such properties, rotational core loss need to be characterized accurately in high frequencies. In this paper, four different magnetizing structures have been analyzed through the finite element method. The influence of the structures on the accuracy has been discussed. A new type magnetizer for high frequency two-dimensional magnetization is developed considering the physical characteristics of nanocrystalline alloy. The yoke geometric structure is optimized, which can extend the measuring frequency up to 10kHz. |
