Abstract

Compact stator structure of conventional hybrid excited flux switching machines (HE-FSMs) suffer from parasitic effects of iron loss and demagnetization due to spatial harmonics in non-overlapped winding that effect electromagnetic performance i.e. average torque ($T_{avg}$), torque density (Tdvg), average power ($P_{avg}$), power density ($P_{den}$), efficiency (n), flux controllability and flux focusing effects. To overcome the aforesaid demerits, in this paper a novel modular H-type stator core is proposed to improve electromagnetic performance, flux controllability and flux focusing effects. Proposed modular HE-FSMs operating principle is analytically discussed whereas electromagnetic performance with varying flux gaps is investigated through finite element method (FEA). Analysis reveals that despite of better flux focusing effects, modular structure ease manufacturing process, transportation, assembly, and on-site maintenance. Finally, comparison of proposed design with existing state of the art exposes that H-type modular structure offers 42.35% higher $T_{avg}$, 42% improved $T_{den}$, better $P_{den}$ by 48.68%, truncate $T_{rip}$ by 13.43% with boost n of 98.6 %.

一种新型的h型模块定子和顺极永磁转子混合励磁电机

传统的混合励磁开关机(HE-FSMs)定子结构紧凑，由于非重叠绕组中的空间谐波影响电磁性能，即平均转矩($T_{avg}$)、转矩密度(Tdvg)、平均功率($P_{avg}$)、功率密度($P_{den}$)、效率(n)、磁通可控性和磁通聚焦效应，导致铁损耗和消磁的产生。为了克服上述缺点，本文提出了一种新型的模块化h型定子铁芯，以提高电磁性能、磁通可控性和磁通聚焦效果。分析讨论了模块化HE-FSMs的工作原理，并通过有限元方法研究了不同磁隙下HE-FSMs的电磁性能。分析表明，模块化结构虽然具有更好的助焊剂聚焦效果，但简化了制造过程、运输、装配和现场维护。最后，与现有技术水平的比较表明，h型模块化结构的$T_{avg}$提高了42.35%，$T_{den}$提高了42%，$P_{den}$提高了48.68%，$T_{rip}$截断了13.43%，boost n为98.6%。
