A wind power generator using induced pressure difference is provided to generate great revolution power with small wind power and to reuse air after generation by floating a windmill blade part with pushing power of opposite polarity magnets and by injecting the air used in generation to the windmill blade. A wind power generator using induced pressure difference comprises the followings: a main body unit(1) installed vertically from ground, having an air path(67) guiding an air flow from a lower portion to a higher portion; a windmill blade part(3) installed above the main body part, having multiple radial blades(2) to be rotated by wind; a rotation axle(4) installed vertically, to support and rotate with the windmill blade part; at least one exhausting fan device(9) installed under the windmill blade part, to inhale air from the main body part and inject the air to the blade by rotating with the rotation axle; a venturi pipe(52A) connecting one end to the exhausting fan device and the other end to the main body part, to increase flowing speed of air through the main body part by reducing sectional area; a generation unit(12) including a turbine housing(48) installed in the venturi pipe, a turbine(47) rotating by air flowing in the venturi pipe, and a generator(51) producing electricity using revolution of the turbine. The windmill blade part rotates on a floating state by permanent magnets having opposite polarity installed each on a frame over the main body part and under the windmill blade part. |
