飞机推进系统的电气化将要求电机的功率密度显著提高，超过当前最先进的水平。永磁同步电机能够实现高功率密度值，但转子拓扑结构的选择对应用很敏感。本文介绍并比较了四种1MW高速永磁电机的设计，包括表面和内部永磁电机的变化。每种设计都符合相同的规格，并与定子模块化兼容，从而提供多种驱动系统优势。所开发的机器的性能和特点进行了比较，并提出了一个初步的PM机设计使用内转子表面PM机拓扑结构作为未来飞机推进系统的候选人作进一步调查。
Electrification of aircraft propulsion will require significant improvements in the power density of electric machines beyond the current state-of-the-art. Permanent magnet (PM)synchronous machines are capable of achieving high power density values, but selection of the rotor topology is sensitive to the application. This paper presents and compares four 1 MW highspeed PM machine designs, including variations of surface and interior PM machines. Each design meets identical specifications and is compatible with stator modularization, which offers multiple drive system benefits. The performance and features of the developed machines are compared, and a preliminary PM machine design using an inner rotor surface PM machine topology is presented for further investigation as a candidate for a future aircraft propulsion system.
