This paper investigates the influence of some leading design parameters on the force performance of a new complementary and modular linear flux-switching permanent-magnet (LFSPM) motor. The originality of the proposed structure is that each phase consists of two E-shaped modules, whose positions are mutually 180 degrees electrical degrees apart. Also, there is a flux barrier between the two modules. First, the structure and influence of some leading design parameters on the force performance of the complementary and modular LFSPM motor are analyzed. Then, a conventional LFSPM motor obtained directly from a rotary FSPM motor is optimized and compared with the complementary and modular LFSPM motor based on finite-element method. The results reveal that the proposed motor has sinusoidal and symmetrical three-phase back electromotive force waveforms and smaller cogging force and force ripple than the existing motors. Moreover, a prototype of the proposed motor is built to validate the study.
