Abstract
This paper investigates the relationship between the distributions of the core loss and the flux density harmonic amplitude along the axial direction in an axial-modular flux-switching permanent-magnet (AM-FSPM) machine. The flux leakage in the no-magnetic ring leads to an uneven distribution of flux density in the core due to the modular cooperation structure. Subsequently, variations in the fundamental flux density amplitudes in the PM field and the armature reaction field are obtained with changes in the thickness of the no-magnetic ring. In addition, the impact of no-magnetic ring thickness on machine torque and core loss is analyzed to determine the optimal thickness for the no-magnetic ring. Finally, the validity of the theoretical analysis is confirmed by experimental validation. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
考虑无磁环影响的轴向模块化磁通开关永磁电机铁芯损耗分析
本文研究了轴向模块式磁通开关永磁（AM-FSPM）电机磁芯损耗与磁通密度谐波幅值沿轴向的分布关系。由于模块化配合结构，无磁环漏磁导致磁芯内磁通密度分布不均匀。得到了永磁磁场和电枢反应场的基频密度幅值随无磁环厚度的变化规律。此外，分析了无磁环厚度对电机转矩和铁芯损耗的影响，确定了无磁环的最佳厚度。最后，通过实验验证了理论分析的有效性。©2024日本电气工程师协会和Wiley期刊有限责任公司。
