<p>PURPOSE: An aerogenerator is provided to prevent damage to an aerogenerator body or front and rear vanes due to strong wind by positioning a main body vertically to the direction of wind using the drive of a drive motor. CONSTITUTION: An aerogenerator comprises a tower rotary shaft(31), a clutch connection shaft(33), a magnet clutch(34), an operational shaft(35), a worm gear(36), a drive motor(38), and a control member. The tower rotary shaft is connected to a main body(1) inside a tower post(30). The clutch connection shaft is connected by a coupling(32). The magnet clutch selectively supplies the torque of the operational shaft to the clutch connection shaft. The operational shaft is connected to the bottom of the magnet clutch. The worm gear is combined with the outer circumference of the operational shaft. The drive motor forwardly and reversely rotates a worm(37) engaging with a worm gear. The control member comprises an encoder(51) and a control unit. The encoder outputs the wind direction information corresponding to the rotation angle of a wind vane(50) installed on the top of the main body.</p> |
