Abstract:
1. A wind power generator comprising: a case; a first rotor having a first main axis in the form of a hollow shaft rotatably installed within a part of said case, a first main blade mounted to an end of said first main axis, coils or a permanent magnet installed on said first main axis; a first stator having a permanent magnet or coils installed on an inner wall of said case to correspond to said first rotor; a first auxiliary blade mounted to an end of a first inner axis which is rotatably installed within said first main axis; a second rotor having a second main axis in the form of a hollow shaft rotatably installed within the other part of said case, a second main blade mounted to an end of said second main axis, coils or a permanent magnet installed on said second main axis; a second stator having a permanent magnet or coils installed on the inner wall of said case to correspond to said second rotor; and a second auxiliary blade mounted to an end of a second inner axis which is rotatably installed within said second main axis, wherein said first main blade and said second main blade rotate in rotational directions opposite to those of said first auxiliary blade and said second auxiliary blade, respectively, and, wherein the rotational force of said first inner axis and the rotational force of said second inner axis may be transmitted to said second main axis and said first main axis, respectively.
