ABSTRACT:
The present invention relates to a wind generator. The wind generator comprises a body installed freely rotatably at a tower, blades installed at a leading end of the body, a gearbox for receiving rotational forces from the blades, and a generator connected to the gearbox for generating electricity. The blades are coupled with a blade angle adjustment unit so that the angles of the blades can be adjusted at predetermined angles according to the directions and velocities of winds. The gearbox comprises a planet gear coupled with a rotational shaft of the blades, a ring gear which has teeth formed on a radially inner surface thereof and engages with the planet gears, and a sun gear which engages with the planet gear and is connected with the generator. Teeth are formed on a radially outer surface of the ring gear so that teeth of a stop gear can be engaged therewith. The wind generator further comprises an electronic brake for controlling the stop gear in such a manner that it stops the rotation of the stop gear and thus causes the ring gear to become stationary.
