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).
