7 assembly ideas homemade windmill

From ancient times, humanity uses the power of wind.The windmills, sailing ships are familiar to many, we wrote about them in books and shoot historical films with their participation.Nowadays wind power generator has not lost relevance since theit can be used to make free electricity in the country, which can also be useful if the light is shut off in the area.Talk about a homemade windmill, which can be assembled from readily available materials and components available.For you, we have provided a detailed instructions with pictures and video ideas several assembly options.Thus, we consider how to make wind turbine with his own hands at home.

Assembly instructions

There are several types of wind turbines: horizontal and vertical turbine.They have fundamental differences, advantages and disadvantages.The principle of operation of the same wind turbine - wind energy is converted into electrical energy and stored in batteries, and since they spent on human needs.The most common type - is horizontal.

The horizontal model

signs and recognizable.The advantage of the horizontal wind turbine - higher efficiency compared to the other, as the wind turbine blades are always under the influence of air flow.The disadvantage is the requirement to wind over 5 meters per second.This type of windmill to make the easiest, so it is often taken as a basis for domestic masters.

If you decide to try your hand at wind turbine assembly with his own hands, here are some recommendations.You should begin with the generator, the heart of the system depends on its setting screw assembly design.To this end, suitable for automobiles, imported, there is information about the use of stepper motors from printers or other office equipment.Bike-wheel motor can also be used to to make a windmill to generate electricity.

Examples of generators

defined the hub of the wind flow into electric current converter, you need to collect the gear speed increasing unit with screws on the generator shaft.One propeller turn transmits 4-5 revolutions on the generator shaft assembly.

An important wind turbine assembly

When assembled unit gearbox-generator begin to clarify his resistance torque (grams per milliliter).To do this, you need to make the shoulder with a counterweight on the shaft of the future installation, and using load to find out at what weight shoulder goes down.Acceptable considered less than 200 grams per square meter.Learning shoulder size, it is our length of the blade.

Many people think that the more blades the better.This is not entirely true, since the wind turbine we do ourselves, and details of the future power plant budget range.We need great speed and a lot of screws provide greater wind resistance, resulting in some point incoming flow slows screw and efficiency of the plant falls.This can be avoided by two bladed propeller.Such a propeller under normal wind can unwind before and more than 1000 rpm.Make a homemade wind turbine blades can be improvised - from plywood and galvanized to plastic from water pipes (as in the photo below), and others.The main condition is lightweight and durable.

What do the blades

Easy screw will increase the efficiency of the wind turbine and sensitivity to air flow.Do not forget to balance the aircraft wheel and remove the irregularities, or during operation of the generator will be listening to the howling and howling.

Balanced blade

Another important element is the tail.It will keep the wheel in the wind stream and rotate the structure in the case of changing its direction.


Make a current collector or not, you decide, will manage possible connector on the cable periodically and manually unscrew it twisted wire.During the test run the wind turbine do not forget about safety, promoted in the flow of the wind blades can chop cabbage like a samurai.

mood balanced wind turbine is mounted on a mast height of not less than 7 meters from the ground, fixed spacing cables.Next equally important node, a storage battery, it may be an old car lost its capacity or battery.Connect the output of homemade wind turbine directly to the battery can not be, it should be done through a charging switch, you can collect yourself, or buy ready-made.

Driving wind turbine assembly

operating principle of the relay is reduced to the control of the charge, but in the case of a charge, it switches on the generator and the battery load ballast, the system tends to be always charged, preventing overcharging, and does not leave the generator without load.Turbine without load may be quite loose to high speed, worked out the potential damage to the winding insulation.In addition, high speed can cause mechanical failure of the wind generator components.Next is the inverter voltage from 12 to 220V 50 Hz to connect household appliances.


Now Internet is full of diagrams and drawings, which show the master how to make wind turbine on powerful magnets themselves.Repeat or not is up to you whether or not it justifies itself, no one knows.But try to collect wind power generating plant for the house is worth, and then decide what to buy and what to leave or make changes.Gain experience and possibly wipe the more serious machine.Freedom and variety of home-made wind turbines is so vast and the element base is diverse, it makes no sense to describe them all, the basic meaning remains the same - the flow of wind spins the screw, it sends to the gear unit time, increasing the shaft speed, the generator produces a voltage, then switch keeps the charge level on thebattery, and it already comes with the selection of energy for different needs.Here on this principle can make a wind turbine with his own hands at home.Hopefully our detailed instructions with photos examples will explain how to make the right model the windmill for the home or garden.Also, be sure to check with master classes for assembling a homemade device that we have provided in the video below.

Here we have provided allthe most simple ideas build a homemade windmill.As you can see, some device models can easily produce even a child.There are many other options samodelok, but in order to obtain high output voltage, it is necessary to use complicated mechanisms such as magnet generators.As for the rest, if you want to make a wind turbine, it worked and used for its intended purpose, act according to the instructions provided by us!
