PCT No. PCT/JP98/02106 Sec. 371 Date Nov. 26, 1999 Sec. 102(e) Date Nov. 26, 1999 PCT Filed May 12, 1998 PCT Pub. No. WO98/54463 PCT Pub. Date Dec. 3, 1998A permanent magnetic dynamo comprises a wind gatherable stand having a tapered outer wall surface that extends from the lower end toward the upper end of the wind gatherable stand in order to guide wind upward; a roof supported through support shafts fixedly standing at the peripheral edge of the wind gatherable stand such that an open space is formed above the wind gatherable stand; a rotary shaft pivotably supported by the roof and the wind gatherable stand and having a horizonal drive blades located in the open space at upper end thereof; a permanent magnetic rotor disposed within the wind gatherable stand and fixed to the rotary shaft to rotate to a vertical axis together with the rotary shaft; stator windings disposed as to face annular permanent magnetic cylindrical portions which are connected to horizontal arm portions constituting the permanent magnetic rotor; and diamagnetic annular attachment plates fixedly provided within the wind gatherable stand, so that the permanent magnetic dynamo can efficiently collect wind blown against the wind gatherable stand to the horizontal drive blades and the degree of cogging phenomenon becomes small.
