Abstract
This paper proposes and analyzes a design approach for flux-switching DC-field (FSDC) machines with harmonics suppression. By purposely selecting appropriate stator/rotor-pole combinations, the even harmonics of phase coils can be cancelled and hence the harmonics suppression of back electromotive force (EMF) of the phase winding. The design criteria are firstly derived from the view of slot star diagram and back-EMF vectors, based on which the mathematics conditions are established. Then, the FSDC machines are optimized by multi-objective genetic algorithm (Moga) coupled with finite-element analysis (FEA) under the fixed copper loss. Consequently, the back-EMF harmonics of the phase winding and coils of the optimized machines are analyzed by FEA. It shows that the even harmonics of back-EMF of phase coils can be cancelled and the phase winding total harmonic distortion (THD) is significantly suppressed by the proposed method.
