摘要

本文提出了一种基于谐波定向减少的双转子磁通调制永磁（DR-FMPM）电机定子铁芯损耗的研究方法。基于磁场调制理论，得出了 DR-FMPM 电机气隙谐波与定子铁芯损耗之间的关系。然后，在分析中考虑了气隙谐波的电枢磁场源和永磁磁场源。通过这种方法，可以识别出只造成损耗而不产生转矩的气隙谐波，并识别出这些谐波的磁场源。在此基础上，提出了针对这些气隙谐波的谐波定向减小设计方法。最后，通过有限元分析（FEA）验证了定子铁芯损耗分析和抑制的有效性。

Research on Stator Loss Suppression of a Dual-Rotor Flux-Modulated PM Motor Based on Harmonic Directional Reduction

In this article, a research method to reduce the stator core loss of dual-rotor flux-modulated permanent magnet (DR-FMPM) motor based on harmonic directional reduction is presented. Based on the field modulation theory, the relationships between airgap harmonics and stator core loss of the DR-FMPM motor is obtained. Then, the armature field and permanent magnet field sources of the air gap harmonics are considered in the analysis. In this manner, the airgap harmonics that only cause loss without contributing to torque are identified, and the magnetic field source of these harmonics can be recognized. Based on this, the design method of harmonic directional reduction for these airgap harmonics are proposed. Finally, the effectiveness of the stator core loss analysis and suppression is verified by finite element analysis (FEA).
