Features of 2000W wind turbine generator:
1. PMG Generator
The generator part consists of the state-of-the-art supercritical generator, the nose cone and the protection cover. Due to its small size and low weight the generator is able to be installed inside the nose cone and before the rotor. This design significantly helps the heat radiation, thus improves the efficiency of the generator and reduces the energy loss.
2. SKF Bearings
Two SKF bearings ensure the reliability and the longevity of our generator. They guarantee the operation in high temperature (150-350º C) and a long life span reaching up to 60000-100000 hours. User may not change the bearings during the wind turbine using, thus the maintenance costs will be reduced.
3. Blades
The blades are made of glass reinforced plastic (GRP) and have passed the strict dynamic balance test before shipping, which promise the efficiency of transforming the wind energy into the mechanical energy.
4. Yawing Mechanism
The mechanism is composed of the 360° Rotation yaw shaft, the tail rod and the rudder blade, which are made of the manganese steel and aluminum alloy. It combines the high strength and the lightness and is able to react to the gusts rapidly.
5. Multi-function Controller "3 in 1"
Hummer multi-function controller "3 in 1" is made especially for 500W and 1000W systems. It combines the functions such as rectifying AC into DC, charging the batteries, inverting DC to AC to power the electrical instruments, and dumping the extra energy which may overload and burn the system, thus protecting the whole system.
6 Guyed Tower
Guyed mast is composed of several segments of steel tubes which are galvanized and spray painted. It is easy to be transported and assembled, especially suitable for the remote area where a crane is not available.
