Wind energy is a converted form of solar energy and is a renewable natural energy that does not produce any pollution emissions. Compared with solar, biological, geothermal and ocean energy power generation, wind power is a new energy with the most commercial-scale development conditions in terms of technology and economy. the

The wind generators in the prior art cannot rotate and generate electricity when the wind force is very small, and the wind is chaotic. If stable voltage and current are required, the diameter of the rotating wind wheel needs to be increased to increase the volume of the entire generator . the

The patent solves the technical problem that general wind turbines cannot rotate when the wind is very small, so that they cannot generate electricity. The permanent magnet magnetic suspension bearing solves the zero friction of the rotor. The coreless disc generator solves the problem of difficulty in starting in the breeze. The counterweight on the top is that the wind wheel produces greater rotational inertia when it rotates. The most important thing is to stabilize the voltage and current and reduce the volume of the entire wind power generator. Compared with other wind power generators, the utility model adopts a fixed The wind guide vane has played the effect of collecting wind and holding the wind and changing the direction of the wind, and it makes the rotating vane without any wind resistance in the predetermined direction of rotation. the

The beneficial effects of the utility model are:

1) The fixed wind guide vane is used to provide the wind kinetic energy at the best angle for the rotating wind wheel. When the wind blows in any direction, it will change the direction through the wind guide vane, thereby providing the wind kinetic energy at the best angle for the rotating wind wheel. The appearance is more beautiful, and the service life can be extended because the rotating wind wheel is not directly exposed to the sun;

2) The rotating wind wheel is composed of two sets of staggered upper and lower sets, and each set consists of three semi-cylindrical blades composed of three semi-circles, which utilizes the wind power to the greatest extent;

3) Three arc-shaped gravity blocks are installed under the disk of the rotating wind wheel, which can increase the rotational inertia of the rotating wind wheel during rotation, stabilize the rotating speed of the rotating wind wheel, stabilize the output current and voltage, and further reduce the The volume of the entire power generation system;

4) Two stages of the same single-pole magnetic ring are used between the rotating wind rotor blade and the fixed wind guide blade, and the rotating wind rotor blade and the fixed wind guide blade are connected to the magnetic suspension bearing. It operates in a suspension state without mechanical friction, which reduces the rotational resistance. the
