摘要

准确估计交流损耗对于设计高输出功率、轻便和安全的超导电机至关重要，特别是用于飞机应用。本研究检测了REBa2Cu3Oy磁带水平阵列中的交流损耗，以开发一种准确估计电机交流损耗的方法。测量了短带和线圈样品的交流损耗。特征参数包括带/线圈的个数n和带/线圈之间的距离g/w，这是超导层宽度归一化的结果。对于小振幅的外加电场，发现交流损耗受n和g/w的影响。随着n的增大或g/w的减小，交流损耗增大。此外，还验证了所提出的交流损耗估计方法的适用性。

AC Loss Property of Horizontal Array of Isolated REBCO Superconducting Tapes and Pancake Coils

Accurate estimation of AC losses is crucial for designing superconducting motors with high output power, lightweight, and safety, particularly for aircraft applications. This study examined the AC losses in a horizontal array of REBa ₂ Cu ₃ O _y tapes to develop an accurate method for estimating AC losses in motors. The AC losses of the short tape samples and coil samples were measured. The characteristic parameters included the number of tapes/coils, n , and the distance between the tapes/coils normalized by the width of the superconducting layer, g / w . For small amplitudes of the applied field, the AC loss was found to be influenced by n and g / w . As n increased or g / w decreased, the AC loss increased. In addition, the applicability of the proposed AC loss estimation method is verified.
