本文综述了高温超导体旋转电机的最新进展。高临界电流密度的散装高温超导体使我们能够设计一个紧凑的配置在一个实用的方案旋转电机。简要介绍了日本东京海洋科学技术大学自2001年以来轴向间隙型陷磁同步旋转电机的研制情况和系统的研究工作。最后，对其他研究小组在高温超导旋转电机方面的研究进展进行了总结。讨论了高温超导块材的材料进展、原位磁化、低温运行时的冷却和交流损耗等关键问题。
The paper contains a review of recent advancements in rotating machines with bulk high-temperature superconductors (HTS). The high critical current density of bulk HTS enables us to design rotating machines with a compact configuration in a practical scheme. The development of an axial-gap-type trapped flux synchronous rotating machine together with the systematic research works at the Tokyo University of Marine Science and Technology since 2001 are briefly introduced. Developments in bulk HTS rotating machines in other research groups are also summarized. The key issues of bulk HTS machines, including material progress of bulk HTS, in situ magnetization, and cooling together with AC loss at low-temperature operation are discussed.
