Diy Wind Turbine Car Alternator. While there are a number of variables that can affect the output of this diy wind turbine, including the efficiency of the alternator used (and obviously the speed of the wind where it's located. It's a permanent magnet alternator, generating 3 phase ac, rectified to dc, and fed to a charge controller.
An alternate energy build this open source diy wind turbine for $30. The last diy vertical wind turbine video was a savonius wind turbine and so is this one. The theoretical maximum power of this turbine is 50watt however, the stepper motor used as a generator has low efficiency with measured maximum power around 20watt.
With a little work, you can convert any gm alternator into an electric generating wind turbine.
Story and photos by robert d. Making construction of a small wind turbine generator a perfect choice. It would take a hurricane force wind to turn a small wind turbine fast enough to even start charging a battery. It was built from scratch consisting largely of recycled components and materials.
