500W Permanent Magnet Alternator wind turbine generator

1.CE proved SCF Supercritical Generator Technology.
2.Tail folding design for strong wind
3.Generator ahead reduce heat easy
Hummer 500w wind turbine windmill output single-phase frequency conversin AC,It has the features of high power efficiency ;low start-up wind speed at 3m/s ;reliable protection of over current /temperature/loading /short circuit etc ;long life design.
H2.7-500W wind turbine with small and light structure features, strong power making ability. Hummer adopt several patented technologies and refined materials.

Hummer H2.7-500w wind turbine have 3 characteristics than traditional wind turbine;
1. Generator: SCF Supercritical Generator Technology as core, Hummer H2.7-500kw wind turbine passed CE test.SCF generator technology takes advantage of special structure and materials to take the generator operate in critical state. So the hummer 500w wind turbine have a very high Wind energy utilizing ratio, produce more power than traditional wind turbine. The SCF generator has been setup the position before the blade inside the Nose Cone it’s most advanced technology comparing the traditional one. And also easy to reduce heat. Hummer owned this patent.
2. SKF (Svenska Kullager Fabriken) bearing:
With the inner and outer ring of bearings processed stably, SKF bearings will perform wonderfully in temperature from -50°C to 350°C.
The perfect inner geometric construction with surface roughness can make bearing with higher rated loading capacity and lower noise.
It has longer life span. SKF bearings’ life span can reach up to 60000-100000, which can greatly reduce the maintenance costs and increase the runtime of the equipment.
3. Tail folding design: the wind turbine will get a very rotate speed if the wind is too strong, such as typhoon. The tail will fold up when the wind is too strong; by this way the folding tail will make angles from the wind direction to lower the rerates speed of the wind turbine. The wind turbine protects itself this way from strong wind. Hummer owned this panent
