Abstract

The aim of this letter is to present a prototyping measurement system for the characterization of ferromagnetic cores under a controlled magnetic field. The main part of the system is a short-circuited magnetizing coil that forms a relatively large square loop. The loop stands fixed in the vertical plane, and it is equipped on one side of the square with a connector for opening and closing of the loop. Thus, a ring-shaped core made of grain-oriented electrical steel can be placed around the loop and become magnetized. A number of measurements have been performed using the system to validate its applicability. Experiments were performed for the sinusoidal and triangular waveforms of the magnetic field, under quasistatic and dynamic conditions. In addition to the presentation of the measurement system, this letter also presents measured hysteresis loops and corresponding energy loss. Part of the results obtained with the presented method are compared with the results obtained using the standardized method. The main features of the measurement system are discussed.

可控磁场波形下铁磁芯特性的测量系统

这封信的目的是提出一个原型测量系统，用于在受控磁场下表征铁磁芯。该系统的主要部分是一个短路的磁化线圈，形成一个相对较大的方形回路。环路固定在垂直平面上，在方形的一侧配备有用于打开和关闭环路的连接器。因此，由晶粒取向的电工钢制成的环形芯可以放置在回路周围并被磁化。使用该系统进行了大量测量，以验证其适用性。在准静态和动态条件下，对磁场的正弦波形和三角波形进行了实验。除了介绍测量系统外，这封信还介绍了测量的磁滞回线和相应的能量损失。用所提出的方法获得的部分结果与用标准化方法获得的结果进行了比较。讨论了测量系统的主要特点。
