PURPOSE: A generator is provided to generate an electrical energy by using an electromagnetic induction generated among the inner rotor, magnet and the outer rotor, while allowing the generator to operate regardless of the existence of wind. CONSTITUTION: A generator(100) comprises a generator housing(110) having a key groove(112) and an open front; a fixed shaft(120) having a key(122) to be accommodated into the key groove, which is extended into a predetermined length in a forward direction; a front cover(130) and a rear cover arranged at the front end and the rear end of the fixed shaft, respectively, in such a manner that the front cover and the rear cover are rotatable; a front bearing(140) and a rear bearing(140a) for coupling the front and rear covers to the front and rear of the fixed shaft, respectively; a cover extension shaft(132) extended from the center of the front cover to the outside of the generator housing; a cylindrical or propeller type impeller(150) arranged at an end of the cover extension shaft, which rotates the front cover through the cover extension shaft; a permanent magnet(160) interposed between the front and rear covers; the first stator(170) fixed at the inner surface of the generator housing, which generators an induced electromotive force corresponding to the magnetic force of the permanent magnet; the second stator(170a) arranged at the fixed shaft, which generates an electrical field between the permanent magnet and the second stator; a commutator(180) arranged at the lower portion of the fixed shaft; a brush(190) fixed at the inner surface of the rear cover, which supplies power from an external source in case of absence of wind; and a housing cover(110a) for covering the open front of the generator housing. |
