Hummer Knowledge
Light, small, swift and stable
Light:
The blades are made of glass reinforced plastic, yaw shaft is made of reinforced aluminum alloy, 2kg weight, 10 percent of the traditional, the tale pole is 500g, 20 percent of the traditional, 350w tower weights 40kg, 25 percent of the traditional.
The inverter adopts amorphous techniques, is 5 percent of the traditional. The unlading system uses light as the unloader weighing only 5 percent of the traditional Heat unloader. The whole compact system weighs only 10 percent of the traditional.
Small:
Small in structure:
The 350W generator is only 18 percent of the traditional; the 1000W is 20 percent of the traditional.
The yaw shaft is 20 percent of the traditional, the square of the tale wing is 70 percent of the traditional, the length of the tale pole is 70 percent of the traditional, if seen from far, only the blades and tale wing are in sight for the 350w wind generator, which is awarded the title as "generator invisible wind turbine? and which is a real miracle.
The "three-in-one-togetherness?tech for the controlling unit , with the dimension as one part of the traditional, is like a sound box, compacted with beauty and utility.
Small in power wastage:
The structure is compact, friction ratio is low, 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 the 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.
Swift:
Swift in installing:
Simple and compact structure, with only three moving parts, convenient fool-proof installation process.
Swift in start up
Low start up wind speed, low 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.
Swift in power outputting:
When the wind is 2.0m/s the output can be 50W.
Swift in charging:
When the wind 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%.
Stable:
Stable in rotating:
Light for the structure and low in barycenter, no eccentricity and upward structure needed, so it is simple for the tower structure, and more reliable.
Stable in wide wind speed:
There is wind speed limitation function, even the speed is over 40m/s, the set can still work normally. The working wind speed is from 2.5m/s to 40m/s. It will not stop rotating in condition of high wind, so the wind utilization is much more.
Stable in heavy wind condition:
The set does not have the bluntness, instability. It is more bearing in heavy wind condition than the head upward generator when it has side-furl and electromagnetic speed limitation protection.
Stable in quality:
ATM volts, current, speed limitation:
Speed limitation-to protect from over speed due to the strong wind, special CMOS chip reduces the power wastage to less than 15%, so the efficiency, the working time is longer than the type of mechanism brake.
Current limitation-reduces the intensity of current and time of over output; protect the generator from over output current.
Volts limitation-to maintain the batteries' charging voltage by controlling the rotating speed of the generator when the battery is full to protect the battery from overcharging.
Stable in lifespan:
The high tech, the automatic controller, the high qualified surface coating etc make the products with 15 to 20 years' lifespan.
Maintenance free
The products are maintenance free with everyday spare parts.
Stable in blades rotating:
The rotor blade s are signed according to airfoil structure. The flexible end joint and balance testing when release, ensure as long as 8 to 10 years working time.
Stable in controlling unit:
The controlling unit is integrated of charging & discharging, inverting & unloading; compact input of wind and solar power; LED digital displaying of input current, and battery voltage; with function of protection for over input, over output, output overloading, with auto alarm system, highly reliable and stable.
