Abstract

One of the most promising applications of high temperature superconducting motors is as traction motors for electric aircraft. However, although optimization of the stator slot shape has a significant effect on the characteristics of the motor, no effective design method has yet been proposed. In this study, the stator slots of a high temperature superconducting induction/synchronous motor with a maximum output of 20 MW were designed using a method called the self-assembling design method. Using the above model, a two-dimensional electromagnetic design was carried out, which simultaneously achieved a power density of 33.4 kW/kg at take-off mode and an efficiency of 97.1% in cruise mode. Furthermore, mechanical stress calculations at maximum output were carried out, and it was confirmed that the results were within the allowable range.

应用自组装设计方法对电动飞机用20mw级高温超导感应/同步电机进行电磁设计与性能分析

高温超导电机最有前途的应用之一是作为电动飞机的牵引电机。然而，虽然定子槽形的优化对电机的特性有显著影响，但目前还没有提出有效的设计方法。本研究采用自组装设计方法对最大输出功率为20 MW的高温超导感应/同步电机定子槽进行了设计。利用上述模型进行了二维电磁设计，同时实现了起飞模式下的功率密度33.4 kW/kg，巡航模式下的效率为97.1%。进行了最大输出时的机械应力计算，确认结果在允许范围内。

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
