Design, prototyping and analysis of a low-cost disk permanent magnet generator with rectangular flat shaped magnets



This paper presents a new structure to overcome some of the difficulties in axial-flux permanent magnet surface-mounted generators. In the new structure with a non-ferromagnetic holder, the centrifugal force acting on permanent magnets is counteracted. Hence, an increase in the rotation speed and the output power of the generator is feasible. The new design is inexpensive and easy to construct. Thus, by development of the proposed structure, it is possible to construct high-speed, low-cost axial-flux permanent magnet generators.
