520 _aThis thesis presents a comparison between using conventional permanent magnet (PM) and Halbach PM array configurations in yokeless and segmented armature axial flux permanent magnet synchronous machines. An analytical model is adopted to carry out the study and finite element models are used to verify the results. A sensitivity analysis is carried out to investigate the effects of motor parameters on performance. An optimization routine is introduced to achieve some performance requirements and fully optimize the machine. The rotor disk design is studied from electromagnetic and mechanical points of views for the conventional PM and Halbach array configurations. From electromagnetic point of view, the rotor flux density is reduced.This allows the reduction of the rotor thickness and better the power density of the machine. However, from mechanical point of view, the air gap flux density increases. Therefore, the rotor thickness needs to be larger to support the rotor fixation for the same rotor displacement
