This paper attempts to design a direct-driven axial flux permanent magnet synchronous generator (AFPMSG) with better design accuracy considering magnetic flux leakages and fringing effect, using D²L design process. Design results of conventional and improved design process are analyzed and compared using 3-D finite element method (FEM). Improved design process shows better accuracy results than the conventional one. Improved design process is utilized to design single and multi-stack AFPMSG topologies. FEM structural analysis is utilized to decrease the intermediate rotor yoke thickness as to improve the output power to weight and output power to volume ratio of three-stack AFPMSG. Finally, characteristics of both single-stack and best model of three-stack AFPMSG topologies are analyzed and compared using 3-D FEM. Although single-stack AFPMSG has less weight and volume and higher power density, its output power depends on its outer rotor diameter. Whereas, three-stack AFPMSG has smaller outer rotor diameter and lower rotor inertia, but it is more costly due to its higher weight and volume and lower power density.
