According to the current of the windmill is about three meters per second wind speed (wind level), it can start generating electricity.
Wind power is the world form a boom for wind power without fuel problems, it does not produce radiation or air pollution.
Wind power in Finland, Denmark and other countries is very popular; western China is also strongly advocated. Efficient small-scale wind power generators system, but it is not only composed by a generator head, but a certain technology in the small systems: wind turbine + charger + digital inverter. Wind turbine by the nose, swivel, rear wing, leaf form. Each part of the very important functions of various parts: leaves used to receive through the nose into the wind power; tail so that leaves always opposite to the direction of the wind to get the most out of the wind; swivel head can rotate in order to achieve flexibility tail to adjust the direction of the function; head of the rotor is permanent magnet, the stator windings cutting magnetic lines to produce electricity.
Fluctuating wind power generation due to wind, so the output is 13 ~ 25V AC change, subject to the charger rectifier, battery charger store again, so that electricity generated by wind turbines into chemical energy. Then protect the inverter circuit, the battery inside the AC 220V chemical energy into electricity, can guarantee the stability of use.
Usually people think that wind power generator wind power entirely by the decision, always wanted to buy a bigger wind turbine, which is not correct. The current to the battery charging wind turbines only, the energy stored by the battery up, people eventually use electric power, size and battery size have a closer relationship. Power depends on the size of even the size of wind, not just the size of the power head. On the mainland, a small wind turbine will be more appropriate than large. Because it is easier to drive and a small amount of wind power generation, continuous small wind, strong wind better than the moment a large supply of energy. When no wind it can also be caused by normal use of wind power, that is a 200W wind turbine can also be a large battery and inverter with the use, access to 500W or 1000W power out even more.
Use of wind generators, wind energy is pouring into our family used to the standard electricity, the savings level is obvious, a family only 20 yuan a year of electricity cost of battery fluid. And now the wind turbine than a few years ago have greatly improved the performance, was only used in a few remote areas, wind generators connected directly to power a 15W light bulb, a clearly a dark and often damage the bulb. And now because of technical progress, the use of advanced chargers, inverters, wind power become  scientific and technological content of the small systems, and can under certain conditions Daiti normal market Dian. Mountain to the system can not be a perennial money-lights; highway signs used it to do the night lights; mountain children can study up under fluorescent lights; urban high-rise roof, wind turbine can also be used, which not only save but also real Green Power. Domestic wind generators, not only to prevent blackouts, but also increase the zest for life. In the tourism area, border, school, military and even behind the mountain, wind turbine procurement is becoming a hot one. Radio enthusiasts could use their own wind power generation technology in the service for the mountain people, so that people watch television and lighting synchronized with the city, but also make their own enrichment work.

The impeller wing section design done carefully by the aerodynamics expert, according to the airscrew structure, takes shape by the intensity glass fiber reinforced plastic, the end joint tech has the extremely low starting and cut-in point, ensures the low wind start and stable quiet running.the wind power utilization ratio enhance up to 0.26 from the traditional 0.5, the extremely high wind power utilization ratio.

Our Hummer Dynamo limited company contrasts the domestic and foreign several small wind-driven generator match blade manufacturer’s blade, through many tests in the foundation, the independent development has designed one kind of new wind blade

In view of the traditional glass fiber reinforced plastic wind blade cannot bear the gale, the low temperature easy break, the gale area service life not to surpass for 5 years and other flaws. Our hummer company developed high strength wind-driven generator wind turbines blade which has controlled the type straight. This wind turbines blade structure is firm, can bear 8 levels of gales.

Our hummerwind turbines mini wind-driven generator adopts outside rotor unique design, reached “own energy consumption low, the wind power utilization ratio to be high the high request. The new wind blade used cut -wind structure, the generator movement does not have the axial force, but can protect outside rotor maximum. Enabled the wind power utilization ratio enhance from traditional 0.26 to 0.43, has achieved the breeze start truly

Hummer wind blade’s successful application causes the problem that gale area such as Inner Mongolian prairie and coast where the wind-driven wind generator’s wind blade damage rate highly, is readily solved. Simultaneously made the entire wind turbine’s service life prolong three to five years. Because hummer mini wind-driven generator wind blade use “the end joint tech stable quiet running, also reduced the noise and has brought enormous convenient for user’s use and replacemen

The wind blade according to the airscrew structure and technics to manufacture, the wind blade has passed through the transient equilibrium test, firm and durable, design life for 8-10 years

After studying rotors blades at home and abroad, Hummer company independently designs a new type blade basing on a lot of tests

The traditional wind turbines  blades made in glass fiber reinforced plastic is not resistant to strong wind, it is easy to break at lower temperature and lasts less 3 years if used in strong wind areas. While Hummer’s blade is solid and resistant to wind 8-grade up, which overcome the shortcomings of traditional products .
