This article proposes a novel axial-modular flux-switching permanent magnet (AM-FSPM) machine, which contains two modular parts and integrated toroidal windings. After investigating the operation principle of the AM-FSPM machine, the modular PM field complementarity and integrated armature reaction field complementarity principles of two AM parts are revealed based on the field modulation theory. Then, a comprehensive comparison of the modulation principle between the AM-FSPM and conventional FSPM machines is conducted from perspectives of the PM field, armature reaction field, cogging torque, and electromagnetic torque production mechanism. It can be found that the modulation principle reveals the difference between the operation principles of two flux-switching machines. In addition, the cogging torque reduction capability of the AM-FSPM machine is investigated, which provides guidance on stator-slot and rotor-pole combinations in the design stage of industrial applications. Moreover, compared with conventional FSPM machines, the AM-FSPM machine exhibits high torque capability and flux weakening capability and, meanwhile, maintains high efficiency at high speed. Furthermore, its characteristics are verified by the experiments.
