35 inch WindGrabber Aluminum Blades (Set of 5) Review
35 inch WindGrabber Aluminum Blades (Set of 5) Feature
- Aircraft-grade aluminum wind turbine blades
- Stainless steel 5/8 inch hub
- Fasteners
For generators with very large permanent magnet motors or 600-1200 Watt PMA's, our three aircraft-grade aluminum WindGrabber blades are designed for 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, WindGrabbers will hit 200 rpm in about 6-7 mph wind. Additionally, it will begin spinning in approximately 1.5-2 mph wind! This is not the blade set that should be used on a modified Delco car alternator. This rotor is far too powerful for a Delco and will spin it out of control! Consider a set of five HyperSpin blades with a stainless steel hub with a 5/8 inch mounting hole, easily compatible with Delco alternators.
