Product Overview
The best low wind rotors for small wind generators! For generators with larger permanent magnet motors, our five aircraft-grade aluminum HyperSpin wind generator blades are designed to spin fast and provide good power! If you live in an area that frequently sees winds above 12 mph, then these wind turbine blades will work well on motors rated for 1000 Watts or more, with a "cut in" speed of 300 rpm or less. If your motor does not fit this description, then see our three-blade HyperSpin series or our three-blade TurboTorque series. The five-blade HyperSpin blade set works well on permanent magnet alternators in the 500 Watt and under category, and on the following small wind generators and PMAs: AirX wind generators, Hornet wind generators, WindBlue PMA, Any other wind generator/PMA in this power range. The five blade set will deliver more torque at a lower start-up wind speed to your PMA-driven wind turbine compared to our three blade model. However, it also gives you a lower rpm than a three-blade set, so be sure to check the specs on your generator before selecting the appropriate blade combo.The wind turbine blades come with a stainless steel hub with a 17 mm center mounting hole.
