Building a wind turbine power system can be a fun project that helps the environment and lowers your electric bill. This article will talk about how to build a wind turbine.
Wind turbines can help you generate free power for your home from a passing breeze and are fairly easy and inexpensive to build. Once you know what components you need to build a wind turbine, it will take you about a weekend to assemble the unit and you’ll be on your way to generating free power.
The principle behind using the wind to generate power was discovered centuries ago and has been used ever since to help with manual labor. Early versions of wind power conversion systems were used to grind grain, or pump water for farms and homes. These older systems were simply sails that were mounted on a spinning platform that would turn when the sails caught the wind. Modern systems are much more efficient and sophisticated, but rely on many of the same principles as these early versions. Today, these wind turbine systems use carefully designed blades made of wood or composite material to catch the wind and spin a shaft connected to a generator. When this generator is turned, it produces a DC current that can be used to power your home. The size of the wind turbine and the generator determine the amount of power that is generated and the larger the turbine, the stronger the wind you need to turn it.
To build a wind turbine you need a few basic components that are assembled into the final unit. These parts include a set of rotor blades, a rotor assembly, a mounting plate for the turbine and a generator. The blades and the rotor are a very specialized assembly and although the average hobbyist can build these, they require a very exact shape and size to be effective. The tolerance on the blades pitch and shape is very small and some people decide to buy these components already built to start their wind turbine. If you do decide to build the blades yourself, there are a wide variety of designs on the web for you to choose for your specifications. Most modern wind turbines use a three-blade design and this seems to give the best balance of rotation and stability. Once you have your blades and rotor sorted out, you need to mount these to a platform that can spin in the wind. With a standard horizontal wind turbine, the blades need to always orient themselves into the wind to start spinning. The platform they are mounted on should be able to rotate to accomplish this. You will also need to mount a vertical rudder on the rear of this platform to manage the alignment into the wind.
Once these are mounted, you need to locate the proper generator for your wind turbine. These generators are available from a variety of sources and vary in size, output and type of current they produce. Most of them output a DC current when spun, but there are also AC current versions available as well. Once you have selected the perfect generator, it needs to be attached to a shaft that is spun by the rotation of the rotor assembly. These generators will usually only produce current when spun in a particular direction, so be sure to match the rotation of the generator with the rotation of your rotor. Once you have the generator mounted and connected to the rotor, you’re all set to place your new wind turbine in an area with a good consistent wind and enjoy the power it produces for you. If you choose a DC version, you can use it to charge some batteries, or power a few small DC appliances. If you need AC power, you can use a simple inverter to convert the DC electricity to AC electricity suitable for powering any standard plug-in appliances.
