Practical advice on how to make a 220V wind generator with your own hands with step-by-step instructions

Tags:With your own hands

In the modern world, more and more money has to be paid for utilities, which include the supply of electricity. Therefore, the owners of private houses are increasingly thinking about how to make a 220V wind generator with their own hands, which can provide the whole house with uninterrupted electricity.

The principle of operation of a wind generator and types of equipment

All wind generators consist of a blade, a turbine rotor, a generator, a generator axis, an inverter and a battery. All models can be conditionally divided into industrial and domestic ones, while the principle of their operation will be the same.

Example of a schematic of a purchased model

Rotating, the rotor creates an alternating current with three phases, which goes through the controller to the battery, and then, in the inverter, is converted into a stable current for supply to electrical appliances.

Simple scheme of work

The rotation of the blades occurs due to a physical effect using an impulse or lifting force, as a result of which the flywheel comes into action, as well as under the influence of a braking force. In the process, the flywheel begins to spin, and the rotor creates a magnetic field on the fixed part of the generator, after which the current is reproduced.

In general, wind generators are divided into vertical and horizontal. Which is related to the location of the axis of rotation.

Vertical option

When planning to create a windmill with your own hands for 220V, first of all, think over exactly the vertical options. Among them are:

Savonius rotor. The simplest, which appeared back in 1924. It is based on two semi-cylinders on a vertical axis. Disadvantages include low use of wind energy.

Savonius rotor variant

With Darrieus rotor. It appeared in 1931, the promotion occurs due to the difference in the resistance of the aerodynamic hump and the pocket of the tape, therefore, the disadvantages include a small torque, as well as the need to mount an odd number of blades.

Helicoid. The blades are spun in shape, reducing bearing load and extending service life. The disadvantage is the high price.

A homemade version will be cheaper if you think it over and mount it correctly.

Horizontal models

Horizontal models are divided according to the number of blades. Their efficiency is higher, but there is a need to install a weather vane to constantly search for the direction of the wind. All models have high rotational speeds; instead of blades, a counterweight is mounted, which affects the air resistance.

Horizontal models option

Multi-blade models can have up to 50 high inertia blades. They can be used to operate water pumps.

How to make a wind generator with your own hands for 220V

To provide a private house with a constant flow of electricity at an average wind speed of 4 m / s, it is enough:

0.15-0.2 kW, which go to basic needs;
1-5 kW for electrical equipment;
20 kW for the whole house with heating.

Homemade model

It should be borne in mind that the wind does not always blow, so you should provide a wind turbine for your home with a battery with a charge controller, as well as an inverter to which the devices are connected.

For any model of a homemade windmill, you will need the basic elements:

rotor - the part that rotates from the wind;
blades, usually they are mounted from wood or light metal;
a generator that will convert wind power into electricity;
a tail that helps to determine the directions of air flows (for the horizontal version);
horizontal yarn for holding the generator, tail and turbine;
match;
connecting wire and shield.

You can use this scheme for assembly

The dashboard will include a battery, a controller and an inverter. Consider two options for how to make a wind generator with your own hands.

Features of assembling a wind generator from a washing machine with your own hands

Consider how to make a 220V wind turbine with your own hands using an engine washing machine old model.

Table 1. Detailed instructions for a wind generator from a washing machine with a photo

What needs to be done	Photo example
You should buy neodymium magnets that are mounted in recesses on the motor rotor. The notches themselves are made on a lathe, use the diagram for correct placement.
You need to glue the magnets onto the prepared grooves with superglue. Then, they should be wrapped in paper, and the rest of the space should be filled with epoxy.
Next, we prepare the axis, which is better to order from a turner. Inside the hollow structure, there should be room for the cable and an opening for its entry. The holder is mounted from an iron bar. For it, we use a grinder, with which we cut off two tubes (fix the generator on them), and weld on the other end.
We turn to the blades, which can be made from a 16 cm pipe for external sewage. In this case, use a jigsaw.
It remains to assemble the wind generator, securing all the elements.To begin with, we attach the generator, blades, rotor and tail to the carrier rail. Remember to cover the generator with a shroud.
The power plant should be secured with a pivot mechanism, and the mast is mounted in a concrete base with 4 bolts.
Route the wire to the distribution board.
Connect all the elements and conduct functional testing.

Features of assembling a vertical wind generator from a car generator with your own hands

When "homemade" people think about how to make 220V wind generators with their own hands, they most often use automobile generators as a basis. It is not difficult to assemble it, but for work you will need:

generator 12V from the car;
battery;
converter from 12 to 220 W with a power of 1.2 kW;
aluminum or steel barrel or bucket for blades;
control lamp from a car;
switch;
voltmeter;
copper wires with a cross section of more than 2 mm;
clamp for fastening.

To assemble a vertical wind generator with your own hands, you will need a tape measure and a pencil, a set of keys, an electric drill and a grinder, as well as scissors for metal. Detailed installation instructions are given below.

Act	Picture
The prepared metal container must be marked and cut into 4 equal parts, only this must not be done completely. In each part, drill holes for the bolts, which should be symmetrical.
The not completely cut blades are slightly bent, the rotation speed directly depends on this process, so decide in advance in which direction the equipment should rotate.
It is necessary to fix the blades on the pulley, and install the generator with clamps on the mast, and also collect the wiring according to the prepared diagram.
The main thing is to correctly connect the wires to which the battery is connected in the shield, as well as the converter.

Finally

With the right selection of elements for a homemade wind generator, you can make a good model that provides the whole house with uninterrupted voltage.

If you are not confident in your abilities or you do not have enough tools, you can buy a household wind turbine, which will pay off by saving on electricity. Such equipment is becoming more and more popular in the conditions of modern economy, it is perfect for private houses.

Homemade wind turbines are usually quiet and reliable, however, the performance is significantly lower than purchased ones. Choose and install equipment to your liking.
