Abstract

Due to inherent high torque density and low pulsating torque, the double-side flux-modulated permanent magnet machines (DS-FMPMMs), which are mounted with PMs on both the stator and rotor, have attracted extensive research attention. DS-FMPMMs have affluent air-gap magnetic field harmonics, which makes this type of machine difficult to analyze quantitatively. In this paper, a quantitative permeance-magnetomotive force (P-MMF) is adopted to obtain the electromagnetic performances of the proposed DS-FMPMMs. In addition, the modulation mechanisms are revealed insightfully in the double-side PMs MMF and the operating principle of the DS-FMPMMs is further explored.
