Research Abstract

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.
