摘要

高功率密度是航空飞行器用电动机关键性能需求,电动机转子结构对功率密度指标具有显著影响.采用磁极偏移结构提高永磁同步电动机功率密度和永磁体利用率.针对150 kW、12 000 r/min额定工作点,基于遗传优化算法开展表贴式、表嵌式以及表嵌式磁极偏移结构永磁同步电动机的优化设计和性能对比研究,并在表嵌式磁极偏移结构基础上对比不同填充材料、磁极偏移角的影响.结果表明,表嵌式磁极偏移结构电动机相比于表贴式结构电动机,可以将功率密度提高2.1%,永磁体用量减小17.6%,转矩脉动降低11.6%,具有良好的应用潜力.

Abstract

High power density is critical to high-performance electrical machines in aviation, and the rotor structures of the machines play an essential role. This paper focuses on the permanent magnet (PM)-shifting rotor to enhance the power density and PM utilization ratio of PM synchronous machines. Aimed at the rated operation point with a power of 150 kW and a speed of 12 000 r/min, global optimizations using the non-dominated sorting genetic algorithm II (NSGA-II) are applied individually to the surface-mounted, surface-inserted, and surface-inserted-shifted PM machines. Then, the three optimal machines are comprehensively evaluated and compared. Additionly, a comparative investigation is conducted on the surface-inserted-shifted PM machines with different structures and different PM shifting angles. The results reveal that surface-inserted-shifted PM machines achieve a 2.1% increase in power density, a 17.6% reduction in PM usage, and an 11.6% decrease in torque ripple compared to conventional surface-mounted PM machines, indicating strong potential for aircraft applications.

Key words： high power density machine; permanent magnet (PM) synchronous machine; permanent magnet-shifting; NSGA-II optimization algorithm
