Structure: Rotor & Generator in this system is designed by direct-coupled way, which can improve reliability and efficiency. 2. Equip with high performances neodymium magnets 3. Wind turbines start operating and reach maximum power at a speed of 3 meters per second 4. Speed limit: Power is controlled by computer automatically as wind speed varies and machines are adjusted at very high wind speeds to protect them from damage. 5. Brake: Compressed air, electromagnetic braking & speed limit system we design can improve safety 6. Wind rotor have wide range, wind rotor &generator are a good match, Wind rotors are worked smoothly through three rotor Blades. Comparing with two rotor blades, it has several advantages. Such as high efficiency, stable etc. 7. Rotor blades: Rotor blades is made of wood-epoxy. All kinds of Climate can be adapted. 8. Tower: High quality tower without rope we design can enhance overall turbine performance.
