PURPOSE: A large capacity generator is provided to reduce the weight and the volume by arranging a stator and a rotor on both sides of the large capacity generator. CONSTITUTION: A rotor part (210) includes a rotary shaft (211), a circular disk (212), a plurality of rotors (213), and a plurality of permanent magnets (214) which are combined with the rotors. The circular disk is vertically combined with one end of the rotary shaft. The rotors are vertically combined with the circular disk. A stator part (220) includes a plurality of stators which separately surround both sides of the rotors. A plurality of coils (230) are combined with both sides of the stators.
