Wind generator is a kind of electromechanical device which can transform mechanical energy into the electrical energy. The wind power generation does not need the fuel; it has no pollution, no noise. It is usually used in places where is far away the electrical network, or even no electricity ,can supply power for refrigerator, washing machine, the illumination, the television, the searchlight, the communication equipment and the power tool uses electricity and others. Wind generator is an electromechanical device which can transform wind energy to mechanical energy, then transforms into the electrical energy. Using wind power generation, it can save electrical energy to the battery charging, also can transform electrical energy to alternating current with output 220V/50Hz, 120V/60Hz, 230V/50Hz. Wind generator with no fuel, no pollution, no noise is a good energy choice for places where is far away from electrical network, or the electrical network not normal. It can supply electricity for air condition, refrigerator, washer, illumination, television, searchlight, communication equipment and many other power tools.
