Axial Flux Coreless Generator
GREEF VAWTs use axial flux coreless disc generator which have following advantage:
1.Torque Patent Technology: use newest "Precise Coil" technology. No hysteresis and gear notches effect make the start torque very low <0.3N.M ,it can make the wind turbine have low start wind speed.
2.Original Structure: use disc coreless motor to take place traditional motor makes it less drag
3. Higher Reliability: special structure make it bigger ratio of power to volume, power to weight and have long life of 8 times longer than traditional motor.
4. Gearless, direct drive, low RPM generator.

FAQ
1. Q: Why buy a small wind turbine?
A: A GREEF wind turbine is a smart investment that will lower your monthly expenses, increase your net worth. At the same time, it will help clean the air, slow climate change, and move us towards the energy independence. You will also enjoy watching your utility meter turn backwards and the lively interaction between the wind and your GREEF turbine. Finally, it will totally change your view of wind you will start appreciating windy days. For those fortunate enough to have a windy site of at least one acre, a GREEF wind system will be substantially less expensive than a comparable solar system, it will take up less space, and its performance won't degrade over time.
It's like buying vs. Renting a home
Over the next 10 years a typical homeowner or small bussiness will pay $18000 to over $5000 in electric bills, at rates that often increse faster than inflation. When you choose a GREEF wind system you take the same monthly expense and invest it in a tangible asset. Once your GREEF turbine is paid off, you will enkoy more money in your pocket every month for the next 20years.
2. Q: Does Vertical Windmill Turbine installation Easy?
A: Very easy, every customer can doin by themselves, we will supply all the components for installation and very details installation manual.
