出于经济原因，高温超导(HTS)电机和发电机等高温超导电机被设计为使用铁芯来缩短高温超导带的长度。在这些情况下，高温超导带被放置在铁芯中，并在交流漏磁场内传输交流电流。研究了铁芯排列方式对交流损耗特性的影响。我们修改了变压器的铁芯，移除了一个矩形段，然后在创建的矩形凹槽中放置了一条高温超导带子。铁芯受到交流线圈产生的交流磁场和传输交流电流的高温超导带的影响。我们将HTS磁带放置在不同的矩形位置，并改变它们的形状。在所有条件下，交流传输电流损失都大于高温超导带材无铁芯时的损失，交流漏磁场产生交流磁化损失。因此，高温超导带在铁芯中的布置方式对交流损耗特性有很大影响，值得进一步研究。
For economic reasons high-temperature superconductor (HTS) machines, such as HTS motors and generators, are designed to use an iron core to reduce the HTS tape length. In these situations, the HTS tapes are positioned in the iron core and transport the ac current within the ac leakage magnetic field. We investigated the influence of the iron core arrangement on ac loss characteristics. We modified the iron core of a transformer by removing a rectangular segment and then positioned an HTS tape in the rectangular recess created. The iron core was affected by the ac magnetic field generated by the ac coil, and the HTS tape transporting the ac current. We placed the HTS tapes in different rectangular positions and varied their shape. In all conditions, the ac transport current losses were greater than losses experienced when the HTS tapes were situated without the iron core, and the ac leakage magnetic fields produce ac magnetization losses. Therefore, how the HTS tape is arranged in the iron core affects the ac loss characteristics and merits further study.
