本文对两种超导电机的电磁特性进行了评估：一类是采用高温超导励磁线圈和铜电枢绕组的超导电机；另一类是采用高温超导励磁线圈和铜电枢绕组的超导电机。另一种是全超导电机，具有高温超导励磁线圈和MgB2超导电枢绕组。 1.5、3.0 和 5.0 MW 电机的设计采用了分析公式和 FEM。我们还考虑了如何降低MgB2绕组结构中的交流损耗。 我们的结果分析主要针对输出密度和效率进行，表明采用超导电机在实现更高输出方面实现电动飞机推进系统更为现实；分析结果表明，全超导电机有潜力达到16kW/kg以上。
This paper evaluates the electromagnetic characteristics as to two types of superconducting motors: one is the superconducting motors adopting high-temperature superconducting field coils and copper armature windings; and the other is fully-superconducting motors, which have high-temperature superconducting field coils and MgB2 superconducting armature windings. Analytical formulas and FEM are employed for the designs of 1.5-, 3.0-, and 5.0-MW motors. We consider how to reduce ac loss in MgB2 winding structure as well. The analysis of our results, which was conducted mainly over output density and efficiency, suggests that the adoption of superconducting motors is more realistic in realizing electrical aircraft propulsion system in terms of higher output; the analysis results show that the fully-superconducting motors have a potential to reach over 16 kw/kg.
