The design AFPM generator is designed following from information of the energy from the location area. As the result, the AFPM generators have 12 poles of magnet and 9 winding coils of the part rotor and stator respectively. The diagram of the designed AFPM generator is shown in Fig. 4, and Table I. Fig. 5 shows the relationship of the height and power water that generate from natural water sources in selected areas. The designed AFPM generator to generate the electric power from 6 meters of water head and 0.l41 m3/min of flow rate is most suitable for installation and operation with acceptable efficiency. In addition the various head of water can generate the different of electric power. The simulation result of electric power versus the head of water is illustrated in Fig. 5.
