5 WIND TURBINE GENERATOR BLADES - POWER ROTOR 80 INCHES

Windy Nation's 5 Blade "Wind Grabber" Set

(Includes everything pictured, including five (5) blades, a stainless-steel hub and stainless-steel mounting hardware)

There are no blades on ebay possessing this power, performance and quality! This is a seriously powerful rotor.

For generators with very large permanent magnet motors or 600-1200 Watt PMA's, our three aircraft-grade aluminum Wind Grabber blades are designed to create extremely high torque and power!  When mounted, the swept area (diameter) of these blades is 80 inches (203 cm). These blades are designed to put out amps on larger motor/generator units. Because a larger rotor inherently spins slower, this blade set should not be used on units that have a "cut in" voltage higher than 250 rpm.

Under no load, the Wind Grabber will hit 200 rpm in about 6-7 mph wind. Additionally, it will begin spinning in approximately 1.5-2 mph wind (That is why we called it the Wind Grabber.).

Please note: This is NOT the blade set that should be used on a modified Delco Car Alternator (sold by many companies on ebay). This rotor is far too powerful for a Delco Car Alternator and will spin it out of control! We recommend our 5-Blade HyperSpin set (w/ 17 mm hub) for Delco Alternators.

Not sure if this blade set is suitable for your motor/generator? Send us a message through ebay with the specs. of your motor/generator and we will be happy to help.

 What is included with your purchase?

1.     Five (5) 35-inch Wind Grabber blades. The blades are 6 inches wide at the base and 35 inches long (diameter of swept area is about 80 inches with the hub). Wind Grabber blades are CNC-manufactured with a dimensional tolerance of 0.005 inches. They are perfectly balanced and spin fast and smooth. They are manufactured from aircraft-grade aluminum, making them light-weight, durable and rust-resistant.

2.     One (1) precision machined, rust-resistant stainless steel hub. It is 0.1875 inches thick and 16 inches in diameter. The center mounting hole is available in 5/8 in diameter or 17 mm diameter (You must inform us after you purchase which diameter you want.). This hub is extremely strong and can handle any stress forces that will be applied by the blades spinning in very strong winds. There is no need to worry about this hub bending or cracking in strong winds.

3.     Mounting hardware: 20 sets of stainless steel locking nuts, bolts and washers.

About Windy Nation's Blades

If you are looking for high quality, professionally designed and precision-manufactured wind generator blades, then these are the blades for you.  These blades are strong, quiet, and durable.  Simply put, they are designed to perform and built to last.  Do not waste your money on blades made of PVC, ABS or plastic.  With the first strong winds, those blades will suffer irreversible stress failure or will just snap, while all our blades can withstand winds of at least 70 mph (This particular blade set has experienced 80 mph winds with no problems.).  Furthermore, all our blades are field-tested and undergo hundreds of hours of prototyping and testing.

            We use ultra-smooth dies to shape these blades, which have been specifically engineered to minimize surface defects.  You will not be disappointed with our blades.  We are certain of their superiority and offer a 90 day warranty.

Below is a short video of three 80 inch WindGrabbers on a permanent magent alternator. You can see for yourself that these blades have some serious power! Five blades will have even more power.

Don't let the camera's frame rate fool you. In person, the blades are an absolute blur!
