<p>A ducted-type wind generator comprises a windmill, a motor drive system and a ducted-type wind generating device. The windmill has a windmill shaft (1) and blades (2) mounted on the windmill shaft. The motor drive system is mounted on a motor frame (19) and connected to the windmill shaft. The motor drive system revolves the windmill shaft (1) so as to rotate the windmill when it is no wind or insufficient wind. The ducted-type wind generating device is mounted on the windmill shaft and generates power by use of the combined wind produced by the rotation of the windmill shaft. The generator is an active wind generator, and the revolutions of the windmill remain constant whenever it is strong wind or weak wind, so the efficiency of power generation is high and electric energy is stable.</p> |
