A reluctance generator includes a circular stator made by silicon steel sheets and amorphous metal, first and second exciting coils, first and second outputting coils, and a rotator disposed in the stator. The stator includes four projecting poles. Two opposite ones and the other two opposite ones of the projecting poles are respectively formed with first and second teeth at distal ends thereof.
