Hummer 2000w éolienne aérogénérateur

Hummer 2000w wind turbine can be applied in both the on-grid system and the off-grid system which uses a battery bank to store the electricity. It can drive a load equal to or less than 2000w.

1. Supercritical generator

Hummer's wind generator adopts the supercritical technology which won a gold award in the 37th Salon Eureka in Brussels and an u.s. patent. This technology significantly reduces generator's weight and size down to 20% to 30% of the traditional one, and the production efficiency is 10% to 30% higher. This ensures that the generator functions perfectly in small wind condition.

2. Skf bearings

Hummer wind turbine adopts two skf (Svenska Kullager Fabriken) bearings which are produced by the largest bearing manufacturer in the world, with the perfect internal geometric structure, known for its life-time endurance and reliable quality. Ordinary bearings need to be changed every two or three years, while skf bearings can greatly reduce the maintenance costs on this matter.

3. Apt speed control

Hummer small wind turbine adopts the electromagnetic brake and the furling mechanism. The electromagnetic brake is used to shut down the wind turbine manually while the furling mechanism makes the wind turbine automatically yaw from the wind direction in order to control the rotation speed of the rotor.
