以磁通流量损失最小为目标，对船舶电力推进用20 MW级高温超导电机的励磁绕组结构进行了优化研究。给出了通过数值分析得到的高温超导磁极线圈形状优化的算例。通过优化磁极线圈的横截面，发现优化后的磁极线圈与矩形基线圈相比，垂直于磁带表面的磁场明显减小。垂直磁场减小的结果表明，磁通流量损失显著减小。文中还指出，优化形状的线圈所需的高温超导带长度增加。
This paper presents the optimization study of the field winding structure of the 20 MW-class HTS motor for the electric ship propulsion based on the minimization of the flux flow loss. The examples of the optimized shape of the HTS field pole coils obtained by the numerical analysis are presented. By optimizing the cross section of the field pole coil, it is found that the magnetic field perpendicular to the tape surface in the optimized shape coil significantly decreases compared with that in the rectangular shape base coil. As the results of the reduction of the perpendicular magnetic field, it is shown that the flux flow loss remarkably decreases. It is also pointed that the necessary length of the HTS tape for the optimized shape coil increases.
