This paper presents an axial flux permanent magnet (AFPM) synchronous generator that was manufactured for the reduction of cogging torque by considering the different angles of a rectangleshaped permanent magnet (RSPM). The placement angle of RSPM was changed from 0 to 28 degrees to obtain total harmonic distortion, line voltage, and cogging torque. A numerical finite element model using Maxwell software was created. The model was validated by the experimental results, with and without a load. The optimum placement angle was obtained at 20 degrees, whose total harmonic distortion (Thd) and cogging torque (Tc) were improved by 41.6% and 71.4%, respectively.
