We developed a pulse magnetization technology for a high temperature superconducting bulk magnet, because the motor / generator for next-generation ship promotion that had the bulk magnet built-in improves the performance drastically. In this study, we aimed for generating a pulse magnetic field suitable for the characteristic of the bulk magnet. A pulse magnetization device possible of the temperature control to less than 30K, a pulse magnetization power supply of the 25kJ output and the magnetic field sensor which could measure surface magnetic induction distribution in succession within 1ms was developed each by us. We tried a pulse magnetization experiment by using them.

我们开发了高温超导块体磁体的脉冲磁化技术，因为内置块体磁体的下一代船舶推广用电动机/发电机的性能大幅提高。在这项研究中，我们的目标是产生适合大块磁体特性的脉冲磁场。我们分别开发了可将温度控制在30K以下的脉冲磁化装置、输出25kJ的脉冲磁化电源以及可在1ms内连续测量表面磁感应分布的磁场传感器。我们利用它们尝试了脉冲磁化实验。
