500W Small Household Wind Power Turbine Generator

Features: 

 

1. SCF Supercritical generator

Hummer wind generator adopts SCF supercritical technology which won a gold award in the *7th Salon Eureka in Brussels. This technology significantly reduces generator’s weight and size down to *5% to *0% of the traditional one, and the production efficiency is *5% to *0% 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. Low noise

The design of the rotor blade of Hummer wind turbine absorbs the highlights of the small aircraft’s airfoil, which is compliance with the aerodynamic standards. It provides a more aesthetic look and a higher efficiency and reduces the noise production as much as possible.

 

4. Double braking protection

Hummer **0W wind turbine adopts double braking protection system, which are the yawing mechanism and electromagnetic braking system to regulate the rotation of the wind turbine. It is safe and convenient to shut down the whole system both manually and automatically.
