N2 - The flux regulation principle of E-core hybrid-excited switched-flux permanent-magnet (HE-SFPM) machine is investigated from a new perspective of variable field harmonics. The investigated machine has a relatively simple structure, as well as improved torque density compared to the parallel HE-SFPM machines resorting to magnetic field short-circuiting based flux adjustment. However, the flux adjustment mechanism of the E-core HE-SFPM machine is not unexplored by the flux modulation effect in depth hitherto. In this paper, a magneto-motive-force (MMF) permeance based model is employed to extract and identify the main working field harmonics. Subsequently, the flux-enhancing and flux-weakening effects are investigated based on the variation patterns of the main air gap field harmonics. The influences of the design parameters on the variable field harmonic effect of the investigated HE-SFPM machine are analyzed, which can provide an underlying mechanism and general design guideline for this type of machine. Finally, the analytical model and finite-element (FE) analyses are experimentally validated by a manufactured prototype.
