Embodiment Construction

[0022] Such as figure 1 shown. A double-rotor permanent magnet breeze generator, including a disc-shaped outer casing 1, an annular inner casing 2 inside the outer casing 1, and the middle of the inner casing 2 is disconnected, and a central axis 3, and the center of the two shell surfaces of the outer casing 1 Bearings 4 are installed respectively, and the central shaft 3 is installed in the bearing 4 at the center of the shell surface of the shell 1 to rotate relative to the bearing 4. One end of the central shaft 3 protrudes from the shell 1, and the protruding end of the central shaft 3 is jacketed with the central shaft. 3. The bearing 5 that is relatively rotated at the protruding end. The bearing 5 on the protruding end of the central shaft 3 is equipped with a fan blade bracket 6 for the fan blade. A pair of steel sleeves 7 are embedded in the inner wall of the edge of the shell 1. The steel sleeve Magnets are packaged in 7 respectively, and outer rotors 8 are respect...

Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a dual-rotor permanent magnet breeze generator. Background technique [0002] With the continuous development of the economy, the depletion of oil resources and environmental pollution, and the intensification of global warming, human beings must grasp the three "E" of economic growth (Economic Growth), environmental protection (Enviromental Protection) and resource supply (Energy Security) Therefore, the comprehensive and efficient development and utilization of new energy-saving energy-saving technologies and environmental technologies has become a topic worthy of research. Wind energy is a conversion form of solar energy. It is a clean and extremely abundant renewable energy. Features such as transportation are required. [0003] At present, a variety of dual-rotor motors for wind power generation have appeared in domestic and foreign literature. In summary, they are...
