This paper investigate the design optimization of a new modular linear flux-switching permanent magnet (MLFSPM) motor with complementary, symmetrical and modular structure and compare its performance with the conventional linear flux-switching permanent magnet (LFSPM). The key of the proposed structure is that each phase armature winding is composed of two coils whose positions are mutually one half of the stator pole pitch and there are flux barrier between the two adjacent "E" models. Hence, the back-EMF waveform of each phase is sinusoidal and the three phase magnet circuits are symmetrical. We first optimize the design and analyze the electromagnetic performance of the proposed MLFSPM motor by means of finite element method (FEM). Then, the structure of the conventional LFSPM motor is also optimized and then compared with the proposed motor based on the same method. The results reveal that the proposed motor has sinusoidal and symmetrical three-phase back-EMF waveforms, smaller cogging force, and smaller force ripple than the existing motors. Moreover, a prototype of the proposed motor is built to validate the study.
