我们研究了电枢绕组结构对采用REBCO带的全超导同步电动机性能的影响。在垂直于磁带平面的方向上施加在磁带上的横向磁场发生变化时，结构对绕组磁带中交流损耗的影响是重要的。一般情况下，将绕组系数减小到1是改善电机性能的有效方法。为此，电枢绕组的形状宜采用鞍形绕组，而不宜采用跑道绕组。本文对500kw级REBCO带的全超导同步电动机性能进行了数值计算。工作温度为65 K。为了验证鞍形绕组的可行性，用YBCO胶带缠绕了5圈试验线圈，并进行了临界电流测量。没有观察到性能的退化。
We investigate effects of armature winding configurations on properties of fully superconducting synchronous motors using REBCO tapes. The effect of the configurations on ac losses in the winding tapes due to the changing transvers magnetic fields applied to the tapes in direction of perpendicular to the flat face of the tapes is important. In generally, it is effective to close winding factor to 1 for improvement of properties of motors. For the purpose, the shape of armature windings is better saddle-shaped winding than race-track winding. In this paper, numerical calculations on the properties of fully superconducting synchronous motors using REBCO tapes with 500 kW class were described. Operating temperature was 65 K. In order to demonstrate the feasibility of saddle-shaped winding, test coil with 5 turns were wound with YBCO tapes and then critical current measurements were carried out. The degradation of the properties has not observed.
