航空航天业制定了雄心勃勃的环境排放和降噪目标，这导致了对未来航空航天运输技术的一些激进提议。确定的颠覆性技术之一是混合动力电力推进。使用电机进行航空航天推进并不是一个新概念。全超导机器有潜力实现大型民用运输飞机应用所需的特定扭矩、功率和效率能力的阶跃变化。然而，全超导机器仍处于起步阶段。本文研究了使用基准航空航天规范的航空航天分布式风扇电机的交流全超导电机的两种不同定子设计概念的电磁设计。选择 1 MW 的基准航空航天规格，并使用传统永磁电机的设计来评估两种等效全超导交流电机设计的性能。交流全超导电机包括安装在传统转子铁芯上的超导块状磁体和安装在非磁芯中的MgB2超导线绕定子。该论文着眼于全超导空芯定子设计以减轻重量，并提出了一种新的无轭定子设计以减少电枢损耗。本文将研究与当前航空航天目标的效率和功率密度相关的不同电机设计的关键设计问题。
The aerospace industry has ambitious environmental emissions and noise reduction targets that have led to some radical proposals for future aerospace transportation technologies. One of the disruptive technologies identified is hybrid electric propulsion. The use of electrical machines for aerospace propulsion is not a new concept. Fully superconducting machines have the potential to deliver the step-change in specific torque, power and efficiency capabilities required for large civil transport aircraft applications. However fully superconducting machines are still in their infancy. This paper looks at the electromagnetic design of two different stator design concepts for an AC fully superconducting machine for an aerospace distributed fan motor using a benchmark aerospace specification. A benchmark aerospace specification of 1 MW was chosen and the design of a conventional permanent-magnet machine was used to assess the performance of the two equivalent fully superconducting AC motor designs. The AC fully superconducting machine includes superconducting bulk magnets mounted on a conventional rotor core and an MgB2 superconducting wire wound stator in a non-magnetic core. The paper looks at a fully superconducting air-cored stator design to reduce weight and a new yokeless stator design is proposed to reduce the armature losses. The paper will look at the key design issues of the different motor designs in relation to the current aerospace targets for efficiency and power densities.
