7 ideas for assembling a homemade windmill

For a long time, mankind has been using the power of the wind. Windmills, sailing ships are familiar to many, they have written about in books and make historical films with their participation. In our time, the wind generator has not lost its relevance, becausewith its help you can make free electricity in the country, which can also come in handy if you turn off the light on the site. Let's talk about homemade windmills, which can be assembled from improvised materials and available parts. For you, we provided one detailed instruction with pictures, as well as video ideas for several more assembly options. So, let's look at how to make a wind generator your own at home.

Assembly instruction

There are several types of wind installations: horizontal and vertical, turbine. They have fundamental differences, pluses and minuses. The principle of operation of all wind generators is the same - the wind energy is converted into electrical energy and accumulates in accumulators, and already from them goes to the needs of the person. The most common form is horizontal.

Horizontal model

Sign and recognize. The advantage of a horizontal wind generator is a higher efficiency compared to others, since the windmill blades are always under the influence of air flow. The disadvantages are the requirement for winds above 5 meters per second. This type of windmill is easiest to make, so it is often taken as a basis for home masters.

If you decided to try your hand at assembling the wind turbine yourself, here are a few recommendations. It is necessary to start with the generator, this is the heart of the system, the design of the screw assembly depends on its parameter. To do this, automotive, imported production, there is information about the use of stepper motors, from printers or other office equipment. A bicycle motor-wheel can also be used to make a windmill for electricity.

Examples of generators

After determining the node of the converter of wind flow into the electric current, it is necessary to assemble the reduction unit of the increase of revolutions from the screw to the shaft of the generator. One revolution of the propeller transmits 4-5 revolutions per shaft of the generator unit.

An important part of the windmill

When the gear-generator assembly is assembled, proceed to determine its resistance to the torque( grams per millimeter).To do this, you need to make a shoulder with a counterweight on the shaft of the future installation, and with the help of the load find out at what weight the shoulder will go down. Acceptably is less than 200 grams per meter. Having learned the size of the shoulder, this is our length of the blade.

Many people think that the more blades the better. This is not entirely true, as the wind generator itself, and the details of the future power plant budget range. We need high speed, and a lot of screws create more resistance to the wind, as a result of which at some point the incoming stream brakes the screw and the efficiency of the installation falls. This can be avoided by two blade propeller. Such a propeller in normal wind can spin up to and more than 1000 revolutions. Make the blades of the self-made wind generator can be from improvised means - from plywood and galvanizing to plastic from water pipes( as in the photo below) and other things. The main condition is light and durable.

Of what to make blades

A lightweight screw will improve the efficiency of the windmill and the sensitivity to airflow. Do not forget to balance the air wheel and remove irregularities, otherwise during the operation of the generator you will listen to howling and howl.

Balanced blades

The next important element is the tail. It will hold the wheel in the wind flow, and rotate the design in the event of a change in its direction.


To make a current collector or not, it's up to you, you can probably bypass the connector on the cable and periodically, manually twist the twisted wire. During the test run of the wind generator, do not forget about safety, untwisted winds can chop the blades like a samurai cabbage.

A tuned, balanced windmill is installed on a mast, not less than 7 meters high from the ground, fixed with spacer cables. Further, no less important node, a storage battery, it can be an old car that has lost its capacity or battery. Connect the output of the homemade wind generator directly to the battery can not be done through the charging relay, you can build it yourself or buy ready.

Wind turbine assembly scheme

The principle of operation of the relay is reduced to charge control, and in the case of charge it switches the generator and the battery to a load ballast, the system tends to always be charged, not permitting recharging, and does not leave the generator without load. A wind turbine without a load can be sufficiently strongly untwisted to high rpm, damage the potential developed insulation in the windings. In addition, high speed can cause mechanical destruction of the elements of the wind generator. Next is a voltage converter with 12 to 220 volts 50 Hz for connecting household appliances.

Now on the Internet full of schemes and drawings, where the master show how to make a wind generator on powerful magnets yourself. To repeat or not, your business, whether it justifies itself, nobody knows. But try to collect a wind power generating set for a house is worth, and then decide what to buy, and what to leave or make changes. Get experience and maybe aim at a more serious device. The freedom and variety of homemade windmills is so extensive and the element base is diverse, that there is no point in describing them all, the main reason is the same - the wind stream untwists the screw, it transmits the torque to the reducer, increasing the shaft speed, the generator generates voltage, then the relay keeps the charge level onaccumulator, and from it already there is a selection of energy for various needs. Here, on this principle, you can make a wind generator with your own hands at home. We hope that our detailed instructions with photo examples have explained to you how to make a suitable windmill model for your home or villa. We also recommend that you familiarize yourself with the master classes for assembling the homemade device, which we provided in the video below.

Intuitive video lessons

To easily make a wind generator for receiving electricity at home, we recommend familiarizing yourself with ready-made ideas on video examples:

So we provided all the simplest ideas for assembling a homemade windmill. As you can see, some models of devices can easily be made even by a child. There are many other options for homemade products, but in order to get a high output voltage, you need to use complex mechanisms, like generators on magnets. Otherwise, if you want to make a wind generator, so that it works and is used for its intended purpose, follow the instructions given by us!
