当前航空航天研究的一个重要推动力是飞机电气化，包括推进系统电气化。为了使电气化推进系统提供优于传统推进的净效益，电气系统必须满足高比功率、功率密度和效率标准。本文介绍了兆瓦级永磁同步电机的目标功率密度为13 kW/kg和96%的效率的组件的实验验证。这表明可以构建适合于该应用的定子。结果与FEA分析非常匹配，并增加了最终电机能够满足设计要求的信心。结果还强调了严格的制造公差的重要性，以最大限度地减少循环电流和相关损耗。
An important thrust in current aerospace research is aircraft electrification, including propulsion system electrification. For an electrified propulsion system to provide net benefit over conventional propulsion, the electrical systems must meet high specific power, power density, and efficiency standards. This paper presents experimental validation of components of a megawatt scale permanent magnet synchronous motor targeting power density of 13 kW/kg and 96% efficiency. This demonstrates that it is possible to build a stator appropriate for this application. The results closely match the FEA analysis and increase confidence that the final motor will be capable meeting the design requirements. The results also highlight the importance of tight manufacturing tolerances to minimize circulating currents and associated losses.
