Abstract :
An axial-flux PM synchronous generator (AFPMSG) for direct-drive wind energy system is studied in this paper. The no-load magnetic field and armature reaction magnetic field in the air gap and the magnets of an AFPMSG are determined by analytical solution of Poisson´s and Laplace´s equations. The computed results show that the magnetic field of the machine comprises mainly an axial component, whereas the circumferential component is prominent only in the pole tip regions
