The generator, blades, nose cone, shaft, tale pole, tale wing, tower, anchor, etc are all surface coated.

1)Generator



The generator you purchased is the most advanced in the world.

It is extreme light and small, high in efficiency--more than 0.78 of utilization ratio.

With four patents here, two of them are international.

The generator is made of special magnetic material, cuprum alloy, intensified stainless steel, and aluminum alloy.

Small and light structure: the 350W only weighs 40kg entirely, 18 percent of the traditional; and 20 percent of the traditional for the 1000W.

Small in power wastage:
The structure and friction ratio are small, low in power wastage with 20% saved than the traditional one.

Small in sound:
Due to the light and small structure, and the rotating speed can never be over 2 times than the rated rotating speed, with the result of soundless, safe and reliable.

Low in rated wind speed:
When wind speed is 6.0m/s, the module 350W can output more than 350W. This wind speed is low than the traditional 8.0m/s rated wind speed.

Simple and compact structure, with only three moving parts, with convenient fool-proof installation process.
Swift in start up: low in start up wind speed, low in rotating wind speed, as 2.0m/s for full start up.

Swift in heat dispersion: the generator is within the nose cone, which is favorable for heat dispersion.

Efficient in charging: when the wind is 2.0m/s the output can be 50W.
Swift in charging: when wind speed is 8.0m/s, the 2pcs 100Ah batteries can be charged full in 6 hours.

Swift in rotating: Hummer generators are different from the traditional outer stator, inner rotor structure. It is designed with patented inner stator, outer rotor structure and with permanent magnet material and circuit, with many accessories saved, so the wind utilization ration is as much as 85%.

2) Rotor blade



Pictures show the new generator wind blade and the wind blade's detail structure.
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.
Used has cut the wind structure, 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 blade which has controlled the type straight. This wind blade structure is firm, can bear 8 levels of gales.
Our hummer 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.
The hummer wind blade's successful application causes the problem that gale area such as Inner Mongolian prairie and coast where the wind-driven 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 replacement.
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.


3) Nose cone



It is in front of blade to reduce the wind resistance. It is made of reinforced aluminum alloy, and streamline design according to theory of the diving boat's sealed design.The generator is within the nose cone, which is favorable for heat dispersion.

4)Protection cover



It is located beween blades and nose cone, being made of reinforced aluminum alloy to further reduce the wind resistance and protect the generator.


5)Yaw shaft



It is made of die-casting alloy, with high intensity and lightweight to connect the blades, the generator, tale pole, tale wing and tower to a whole unit. Inside of the shaft there are slip rings to prevent the wires go winding. The 2kw weight is only 10 percent of the traditional, and 20 percent of the traditional dimension.

6)Tail pole



They are made of manganese steel, with high intensity and lightweight, length only as two thirds of the traditional pole.

7)Tail wing



It is made of stainless steel, inflexible, auto side furling in high wind condition, reliable and delicacy in speed limitation, with weight 500g, is 20 percent of the traditional.


8)Tower



It is made by carbon steel, with outer diameter65,76,90,120, height 5m,6m,8m, etc with 2 or 3 sections per unit. They are anticorrosion, as well as UV-proof. Because the head and tower need not adopt the eccentricity structure, the mount structure is simpler, and more reliable.

9)Guyed wires and anchors





Tightwire adopts live button structure, and arrow like anchor, so it is much easier for installation

10)Surface coating and protection

All the parts are galvanized and then static molded, so are anticorrosion, UV-proof, crashworthy, fastness and will be fresh all year round.

All the parts are made of high quality aluminum alloy and die-casting spare parts, can be used in the temperature ranging from -30 to 60, in the surroundings of high wet, and sand salt or frost area.
