GREEF 3KW Vertical axis wind generator (VAWTs) is a type of wind generator where the main rotor shaft is set vertically. VAWTs offer a number of advantages over traditional horizontal-axis wind generator (HAWTs). They can be packed closer together in wind farms, allowing more in a given space. They are smaller, but rather due to the slowing effect on the air that HAWTs have, forcing designers to separate them by ten times their width.
GC-3KW vertical Axis wind generator are rugged, quiet, light, Omni-directional, and they do not create as much stress on the support structure. They do not require as much wind to generate power, thus allowing them to be installation at urban .They are easily maintained and can be installed on rooftop and similar tall structures.
Recommend for
• Household, Garden, farm
• Telecom sites. • Rural electrification programs. Island , sentry, island, sight lighting.
The VAWT 3kw Grid-tie system is often used in conjunction with solar panels to provide more reliable year-round energy supply.

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.
