This article proposes a multilevel optimization design approach based on airgap harmonics for a double-stator flux-modulated permanent-magnet (DS-FMPM) motor, utilizing flux modulation theory. The method optimizes motor design at different levels, integrating response surface method, sensitivity analysis, and genetic algorithm, resulting in the successful manufacturing and testing of a prototype motor with verified feasibility.
In this article, based on flux modulation theory, an airgap-harmonic-based multilevel optimization design approach is proposed for a double-stator flux-modulated permanent-magnet (DS-FMPM) motor. The proposed DS-FMPM motor is purposefully designed, so as to realize the design requirements of driving cycle. In the proposed optimization approach, based on three fundamental elements of general flux modulation theory, motor optimization design is carried out from three levels. Furthermore, a response surface method, sensitivity analysis, and a genetic algorithm are purposely employed in different levels to obtain optimal motor design. In addition, electromagnetic performances of a DS-FMPM motor are demonstrated in detail. Finally, a prototype motor is manufactured and tested. Both simulation and experimental results verify the feasibility of the DS-FMPM motor and the effectiveness of the proposed airgap-harmonic-based multilevel optimization design approach.
