One Set of 3 "WINDMAX" Brand, High Efficiency, Light Weight, Load Balanced, Reinforced Fiberglass Commercial Wind Turbine Rotor Blades, 8.5 Feet (2.6 meters) diameter.
For 1000w and up generators
How to match the rotor blades to the generator
A small rotor with a big generator will not generate the full power, while a small generator with a big rotor will generate full power at low winds. But the large rotor will require a strong tower and require better control in high winds, the generator will also need to run at lower RPM.
According to Hugh Piggott’s book, "The usual compromise is to choose a generator which reaches full output in a wind speed around ten meters per second (10 m/s).” “If the generator and the rotor are well matched, this will occur at the design tip speed ratio, and the maximum will be extracted from the wind.”

Streamlined light weight blade design to achieve maximum energy output and efficiency.
Optimized aerodynamic design to offer the best performance with minimized load.
3-blade rotor design provides the best balance of high rotation speed, load balancing and simplicity.
Load balanced with perfectly sanded smooth surface.
The power coefficient (Cp) tells you how efficiently a turbine converts the energy in the wind to electricity, the theoretical maximum of CP is 0.593, actual rotors convert less than this limit (approximately 0.3 – 0.5).
Tip Speed Ratio (TSR) for WINDMAX blades is designed to operate at optimal TSR under low, normal wind and high wind conditions so that maximum wind power is captured under any wind speed.
Tip Speed Ratio (TSR) is the ratio between the linear speed of the tip of the blade with respect to the wind speed.Typical tip speed ratios are 1 thru 10. The performance of a blade’s airfoil (shape) is a function of the TSR.
Tip Speed Ratio (tsr) = (tip speed of blade) / (wind speed).

"Windmax" turbine blades is the market leader in worldwide small wind turbine market, "Windmax" blades provides top quality, excellent performance, and long lasting service life.
All the Wind Turbine blades are manufactured in state of art manufacturing facilities by our experienced staff. The top notch quality come from better research and development, better selectivity of materials, better process control, better production technique and better quality control. Each blade must pass performance evaluation and stringent quality testing before it is released to the market.
Consumer Beware: We found that some of our competitors have tried to copy our blade design ! these poorly made blade copies from our competitors have lower quality, more defects, lower performance and shorter service life. These defective blade copies are made of poor quality fiber glass material that last much less time than our blades.
Some competitors have also made false claims about the performance and quality of their blades.
Buyers beware of these FRAUDULENT, UNETHICAL Competitor Scams !
Weight of each blade is estimate only, it may not be the actual weight
*Wind turbine blades do not include a warranty.
There are too many variables on the installation to a myriad of generator designs, locales and expertise of the installers.

Many materials have unpaired electron spins, and the majority of these materials are paramagnetic. When the spins interact with each other in such a way that the spins align spontaneously, the materials are called ferromagnetic (what is often loosely termed as "magnetic"). Due to the way their regular crystalline atomic structure causes their spins to interact, some metals are (ferro)magnetic when found in their natural states, as ores. These include iron ore (magnetite or lodestone), cobalt and nickel, as well the rare earth metals gadolinium and dysprosium (when at a very low temperature). Such naturally occurring (ferro)magnets were used in the first experiments with magnetism. Technology has since expanded the availability of magnetic materials to include various manmade products, all based, however, on naturally magnetic elements.
Not only do we have a collection of ceramic magnets but we also have a large range of Neodymium Magnets as well. These magnets are very robust in relation to their size. Popular with industries and hobbyists. Neodymium magnets are used in a wide variety of applications. From hard drives to headphones to loudspeakers these magnets have seen it all.
Ceramic Magnets or ferrite
Ceramic magnets, or ferrite, are made of a sintered composite of powdered iron oxide and barium/strontium carbonate ceramic. Due to the low cost of the materials and manufacturing methods, inexpensive Ceramic magnets (or nonmagnetized ferromagnetic cores, for use in electronic component such as radio antennas, for example) of various shapes can be easily mass produced. The resulting Ceramic magnets are noncorroding, but brittle and must be treated like other ceramics.
Neodymium magnets, more formally referred to as neodymium-iron-boron (NdFeB) magnets, have the highest magnetic field strength, but are inferior to samarium cobalt in resistance to oxidation and temperature. This type of magnet has traditionally been expensive, due to both the cost of raw materials and licensing of the patents involved. This high cost limited their use to applications where such high strengths from a compact magnet are critical. Use of protective surface treatments such as gold, nickel, zinc and tin plating and epoxy resin coating can provide corrosion protection where required. Beginning in the 1980s, NIB magnets have increasingly become less expensive and more popular in other applications such as children's magnetic building toys. Even tiny neodymium magnets are very powerful and have important safety considerations.At Applied Magnets you will get the best possible price on these Neodymium magnets. All you have to do is just browse and choose from our huge selection and we will do the rest. Plus with shopping online you get the modern convenience of buying from your home or place of business.
