The design considerations of AC machines with windings made of high-temperature superconductors (HTS) are presented in the following paper. The considerations were narrowed to permanent-magnet excitation machines, although the results can be extrapolated to many other machine types as general guidelines. The influence of basic machine parameters and coefficients during the design of such machines are considered in order to estimate operating conditions of HTS windings. The number of poles, number of slots or slot dimensions, coil placement, and arrangement, are taken into account with the intent to fully utilize features of superconducting materials such as the capability of conducting high current density without significant losses. The attention is placed on low power machines, below 1 kW, operating at liquid nitrogen temperature (77 K). For analysis purposes, the finite element method (FEM) is used to calculate the distribution of the magnetic field and its effect on the critical current of the HTS coil. The numerical analysis is carried out in ANSYS software.

高温超导永磁励磁交流电机的电枢绕组分析

下文介绍了采用高温超导体（HTS）制成的绕组的交流电机的设计注意事项。尽管可以将结果外推到许多其他类型的机器作为通用准则，但考虑的范围仅限于永磁励磁机。为了估计高温超导绕组的工作条件，在设计此类电机时考虑了基本电机参数和系数的影响。为了充分利用超导材料的特性，例如传导高电流密度而没有明显损耗的能力，考虑了极数，槽数或槽尺寸，线圈放置和布置。重点放在运行在液氮温度（77 K）下的1 kW以下的低功率机器上。出于分析目的，使用有限元方法（FEM）计算磁场的分布及其对高温超导线圈临界电流的影响。数值分析在ANSYS软件中进行。
