Interruptions in the central power supply, as well as exorbitant electricity bills, are increasingly forcing people to think about an autonomous power source. Let the generator be low-power, and work only as a backup source of energy, but it can help out at the most important moment.
We also decided not to stand aside and offer a "workable version" of the conversion of the induction motor from the old washing machine in a sufficiently powerful generator of 1.5 kW.
If you decide to “quickly bungle” your own home-made electric generator by “riveting” the engine from the washing machine, it’s better to immediately discard the illusions to the side, because it won’t work “quickly”. To begin with, three main problems will need to be solved:
Let's solve the first problem. Let's take an asynchronous motor from an old "washer", disassemble its body, and then, using a lathe, cut off part of the core to a depth of about 2 mm. Let's put the engine aside for now. Next, we will need to purchase a set of neodymium magnets, it is easiest to order them in an online store. We are waiting for the magnets to come.
After that, we cut out on the machine the grooves on the motor core, 5 mm deep, for the magnets. Here you need to masterfully master the lathe, it is best to call for help some familiar turner. After you prepare the motor core, you will need to think about what to make a template for attaching magnets from. We used a strip of tin, although we admit that other material with similar properties may be suitable. We cut the strip along the length and width so that it fits exactly on the surface of the core.
The tin strip must also be prepared, namely, mark it along its entire length to place 2 rows of magnets on it so that the magnets are located at the same distance. Further, to convert the electric motor of the washing machine into a generator, we need superglue, cold welding, you can take epoxy resin instead of welding, as well as sandpaper.
Note! It is better to take cold welding, it is easier to work with, besides, it will immediately help to better fix the magnets, making it easier for you to stick them.
Everything you need to make a generator out of an engine washing machine we have prepared, now you can start the assembly process. We note right away that only a very patient person can do this work with their own hands. The magnets constantly jump off and stick together, the glue flies in all directions, falling not only on the hands, but also on the face, so be extremely careful and follow the safety rules when working with potentially dangerous chemicals. We do the following:
Important! The distance between the magnets and the angle must be the same, otherwise, during the operation of the generator, frequent sticking will occur, accompanied by a drop in power.
We have finished making an electric generator from a washing machine motor, now we can proceed to the long-awaited tests. In order to check the generator, we need:
You also need to think about how you will turn the generator. Fingers are not an option, you will not be able to provide enough turns. It is best to use a screwdriver or an electric drill for these purposes. We find two wires of the working winding on our generator, and cut the rest. We connect these wires through a rectifier to the charge controller, and in turn we connect it to the battery. We throw the multimeter crocodiles on the battery terminals - that's all and it's ready to test the generator.
We charge an electric drill into the chuck (you can use a screwdriver), a generator pulley and spin it up to 800-1000 revolutions. At the output, we get 270 volts with moderate sticking of the magnets - not a bad result.
Many are wondering, well, we made such a generator, and what, how to use it in the household so that it brings benefits? Personally, we made this generator with an eye on self-manufacturing gasoline power plant from a morally obsolete, but working Soviet Druzhba chainsaw. According to our calculations, the design should have turned out to be cheap, which cannot be said about factory gasoline stations.
As a result, we managed to realize our idea. We connected the chainsaw engine to our generator through a drive belt, securing everything on the frame from the same chainsaw. I didn’t even have to weld the frame separately. Our power plant has been working properly for the second year, supplying all energy consumers in the country house. There is enough power to light two rooms, to ensure the operation of a computer and a TV.
There are other options for using a homemade generator. The article eloquently describes the process of manufacturing an installation that, using the natural force of the wind, can supply energy to the same country house or a garage. Some suggest using this generator to power the ski lift. In general, connect your imagination, and you will also find a couple of ways.
In conclusion, we note that the manufacture of a home-made generator is fraught with certain difficulties. The main difficulty lies in gluing the magnets when creating the rotor. But you can go in a simple way - order a ready-made magnetic rotor. In this case, the generator will cost you 200 rubles more, but you will save a lot of time.
Electricity is a rather expensive source, whose environmental safety is in doubt. This is due to the fact that hydrocarbons are used to produce electricity. These processes not only consume subsoil, but also poison environment. You can provide the room with wind energy. Such installations are not cheap, but you can make a wind generator from a washing machine engine with your own hands.
Such devices are rarely used as the main sources of electricity, but as additional ones they are quite optimal. This is ideal for giving country houses, which are located in places where power outages often occur. Homemade construction from the engine of a washing machine or a screwdriver will be very cheap and will help save significant amounts on energy costs.
This is a great solution for thrifty hosts who do not want to overpay and are willing to work hard to reduce costs. The classical design includes mechanical devices, the main purpose of which is the conversion of the kinetic energy of the wind into mechanical, and then into electrical. The bulk modern models equipped with three blades. This is necessary to increase the efficiency. They begin to function at a wind speed of 2–3 m/s.
Wind speed is the most important indicator, because the performance of the unit depends on it. In the technical documents for industrial windmills, indicators are always indicated at which the product operates with maximum efficiency parameters. In most cases, this value is 9−10 m/s.
There are also maximum allowable wind speeds. They vary between 23−25 m/s. With such indicators, the efficiency of the wind generator is significantly reduced, because the blades of the unit change position. If we talk about a self-made installation, it is extremely difficult to calculate the technical characteristics in it.
It is necessary to focus on average values, and then calculate right amount electricity for basic needs.
Installing a wind turbine is justified if the wind speed exceeds 4 m/s. In such a situation almost all needs can be met:
When making a wind generator from a washing machine with your own hands, you should take into account the instability of the wind speed.
Electricity can disappear at any moment, so household appliances must not be connected directly to the device. This requires batteries and a device to control the charge, since electrical equipment requires a voltage of 220 V.
To make the unit with your own hands, you will need to buy several parts. Many of them can probably be found in old household appliances, but some will need to be purchased. Main elements:
If you purchase a ready-made station, along with the installation you need to pay 70-80 thousand rubles. A home-made wind generator will cost no more than 3.5-4 thousand rubles.
The difference in cost is significant, so it is advisable to make and install the structure on your own. The result is a unit with a power rating of about 2.5 kW. This is quite enough for the functioning of household appliances.
All wind turbines are different, regardless of whether they are industrial or do-it-yourself. Their classification is carried out on several grounds:
With the independent production of a windmill, you first need to decide on the design. In addition, it is necessary to calculate the required power taking into account the operating conditions.
Horizontal structures are more preferable because their production does not require high-precision calculations. Such a windmill is much easier to make, it starts to work even with a small wind. The disadvantage is the bulkiness of the product and noise during operation.
The vertical unit is suitable for those who have time to assemble and install a complex but compact system. The windmill operates by moving the blades that are attached to the rotor. The latter is fixed on the generator shaft, which generates a flow of electricity. Further, the energy is supplied to the battery devices, where it accumulates, and then supplies power to household appliances.
Windmills have been popular for a very long time. Designs are constantly being improved, and the wind is an easily accessible energy source. Devices powered by it environmental plan safe and convenient, because they are placed on masts, without occupying usable space. The units are easy to maintain and repair.
Structures emit sound during operation. The noise can be louder or quieter, but it is always present. Often this aspect interferes with the owners of the house and neighbors. There are other disadvantages as well.
Wind is an extremely unpredictable element. Because of this, the activity of the generator is unstable, so you need to accumulate energy so that in calm weather you will not be left without electricity.
For the production of a wind generator, you will need an engine from a washing machine with a capacity of 1.5 kW. Besides, you will need:
Magnets can be bought online or retail chains. They need to be installed on the rotor. From the latter, it is necessary to remove the cores or cut off part of them on a lathe. Then they make grooves with a depth of 5 mm.
When the design is ready, it is necessary to install the magnets in the places provided. First of all, a tin coating is made for the core, and then the magnets are installed at the same distance from each other. It is important to observe the distance, otherwise the magnets will stick together during operation, and the performance of the device will be significantly reduced.
The finished magnetic template is placed on the rotor, and the gaps are filled with epoxy. When the procedure is over, clamp the rotor in a vise and carefully sand the surface with sandpaper. After that, the condition of the bolts on the bearing and housing should be checked. If the elements are worn out, it is recommended to replace them.
To check the operation of the assembled wind generator, you will need additional devices. Among them:
First of all, you need to determine which wires come from the working winding, and remove all the rest.
These conductors must be connected to the rectifier. The latter is connected to the controller, which is connected to the battery. The system is ready for testing.
The power of the windmill is checked as follows: a voltmeter is brought to the battery, and the assembled unit is spun with an ordinary drill or screwdriver. It should be noted that the speed of the latter must be at least 800 rpm, best option- 1000. Normal indicators are 200-300 V.
When assembling a wind turbine from a washing machine, it may be difficult to manufacture an impeller. You need to choose a lightweight, but at the same time durable material. A good solution is fiberglass blades. They are light in weight, but very reliable and durable. For the mast, steel pipes with a diameter of 32 mm are enough.
The first step is to choose a suitable place for the wind generator. It is desirable to install the support in an open area, the top of the hill is best suited for this. Many experienced craftsmen believe that the higher the supporting structure, the better. Step by step:
To protect the wind turbine from various weather conditions, you can make a canopy over it. Such designs significantly increase the operational life of the product.
Experts do not advise immediately connecting expensive and powerful household appliances to the windmill. First you need to test the design on a phone charger or other simple devices.
A wind generator is the best option as an alternative source of energy, but it can also become the main one for small buildings or country houses. A homemade device will work for more than one year. In addition, a hand-made product will significantly save the family budget. The main thing is to carefully study the information and not be afraid of experiments.
Problems with electrical energy, which usually arise unexpectedly, force many consumers to think about the device of an autonomous power supply. Moreover, exorbitant bills for the use of the industrial network are also pushing for this. Installing an autonomous power source in the house is considered a profitable business. This device is able to come to the rescue when the industrial power supply is turned off.
Its power indicator is relatively small, but this is quite enough to act as a backup power source. Purchasing a generator on purpose is an expensive pleasure, but making it yourself is quite realistic. Today we will consider how to make a generator from a washing machine engine with your own hands.
It seems to many that making a homemade electric generator from is a simple matter. Drop all illusions, because you will not be able to quickly cope with such a task. First of all, three main problematic issues should be dealt with:
Having prepared everything you need, we can begin to work. We immediately warn you that it will take a lot of patience to make the desired element from the washing machine engine. Magnets will constantly jump off and stick to each other, you will smear everything with glue, so we recommend that you use caution and safety requirements when working with potentially harmful chemical compounds.
The algorithm of actions is as follows:
The process of manufacturing a generator from an engine is completed, it remains to test it in action. To perform the check you will need:
Think about how the rotation will be carried out. You won’t be able to do this with your fingers, because you won’t be able to create the required number of revolutions. We recommend using an electric drill or screwdriver.
We determine a pair of working wires on the prepared device, cut off the rest. We connect the wires through the rectifier to the charge controller, and then to the battery. We fix the fasteners of the multimeter on the battery terminals - the generator is ready for testing.
We charge the generator pulley into the cartridge of the power tool, with the help of which the promotion will be performed, and give revolutions in the range of 800 - 1000 rotations. As a result, with moderate sticking of the magnets, 270 volts should be obtained, which will turn out to be quite an acceptable indicator.
What is the best way to use such a device? If you install a generator on a chainsaw, you get a small power plant, the energy of which will be enough to light two small rooms, run a computer, and even watch TV.
It is possible to connect the generator to a hydro turbine installed in a domestic waterfall or fast-flowing stream.
Some install wind turbines and generate electrical energy from the mechanical energy received. For this, generators are suitable not only from an asynchronous, but also a collector motor. An alternative power source is quite safe, able to start at a wind speed of two to three meters per second. But with ten-meter gusts of wind, such a generator will reach its maximum efficiency, although four meters will be enough for home consumption, allowing it to generate 0.15 - 0.20 kW, which will be quite enough to light the room and watch TV.
At 1 - 5 kW, feel free to turn on the computer, refrigerator and even the washing machine. But 20 kW will already be enough to supply heat to the heating system.
It is best if the windmill you install turns out to be three-bladed - as it is the most efficient in operation. Use a steel bar as its basis, on which you attach the generator, blades and rotor. Consider protection for the generator so that it does not suffer from adverse weather conditions. For the moving part of the wind turbine, provide a hinged mount. We lay a wire from the generator along the length of the mast, bring it to the shield, connect the controller, inverter and battery device. As you can see, the connection diagram is simple.
With patience, you can independently make an electric power generator from the electric motor of an old washing machine, which will come to your aid in difficult times. Besides, with such a home-made installation, you can start saving money on utility bills.
The electric motor of a washing machine is a very valuable and useful thing. Getting it is not as difficult as it might seem at first glance. Washing machines break down with depressing regularity. The most interesting thing is that the motor from the washing machine can be turned into a 220 volt generator. There is only one "small" problem on the way.
So, the washing machine engine has a classic commutator motor design. The device can operate on both direct and alternating current. Most motors have 6 pins on the connection block. The bottom pair is the rotor output. The middle pair is the stator winding. The top pair is for the tachometer sensor. In order for the motor to start working, some force, a small voltage, must be applied to it.
The voltage on the motor will create a magnetic field, and this in turn will create an EMF on the stator winding. All this means that wires can be connected to the rotor, which will later transfer energy from the power source. As a source of energy for the motor, you can use a 12 V battery. At the same time, to start the generator, if you need to turn it by hand.
That's what it's all about the main problem. The washing machine motor is quite suitable to be used as a generator. However, (including) due to the lack of permanent magnets, it is impossible to stably create an EMF on it. The generation of direct current requires high speeds, which can only be achieved manually. Therefore, it will be quite difficult to “attach” such a thing somewhere.
In continuation of the topic, read about and not only.
Homemade products from the engine from the washing machine (video selection, photos, diagrams)
1. How to connect the motor from an old washing machine with or without a capacitor
Not all "washer" motors will work with a capacitor.
There are 2 main types of engines:
- with capacitor start (constantly switched on capacitor)
- with starting relay.
As a rule, "capacitor" motors have three winding outputs, power 100 -120 W and revolutions 2700 - 2850 (motors of centrifuges of washing machines).
And engines with a "start relay" have 4 outputs, a power of 180 W and a speed of 1370 - 1450 (washing machine activator drive)
Connecting a "capacitor" motor through the start button may result in loss of power.
And the use of a constantly on capacitor in a motor designed for a starting relay can lead to burnout of the windings!
2. Homemade emery from the engine of a washing machine
Today we are going to talk about transformation. asynchronous motor from the washing machine to the generator. In general, I have been interested in this issue for a long time, but there was no particular desire to remake the electric motor, since at that time I did not see the scope of the generator. Since the beginning of the year, work has been going on on a new model of the ski lift. Having your own lift is a good thing, but riding with music is much more fun, so I quickly got the idea to make such a generator so that I can use it on the slope in winter to charge the battery.
I had three electric motors from the washing machine in store, and two of them are absolutely serviceable. Here I decided to convert one of these asynchronous electric motors into a generator.
Looking ahead a little, I will say that the idea is not mine and not new. I will only describe the process of converting an induction motor into a generator.
The electric motor of a washing machine with a capacity of 180 watts, manufactured in China in the early 90s of the last century, was taken as a basis.
I ordered magnets from NPK Magnets and Systems LLC, before I had already bought magnets during the construction of a wind farm. Neodymium magnets, magnet size 20x10x5. The cost of 32 pieces of magnets with delivery is 1240 rubles.
Alteration of the rotor consisted in removing the core layer (deepening). Neodymium magnets will be installed in the resulting recess. At the beginning, 2 mm of the core was removed on a lathe - a protrusion above the side cheeks. Then a 5 mm recess was made for neodymium magnets. The result of the alteration of the rotor can be seen in the photo.
By measuring the circumference of the resulting rotor, were produced necessary calculations, after which a strip template was made from tin. Using a template, the rotor was divided into equal parts. Neodymium magnets will then be glued between the risks.
8 magnets were used per pole. In total, 4 poles turned out on the rotor. With the help of a compass and a marker, all the magnets were marked for convenience. Magnets were glued to the rotor with “Superglue”. Let me tell you, it's hard work. The magnets are very strong, I had to hold them tightly when gluing. There were moments when the magnets came off, pinched fingers, and glue flew into the eyes. Therefore, you need to glue magnets with the use of goggles.
I decided to fill the cavity between the magnets with epoxy resin. To do this, the rotor with magnets was wrapped in several layers of paper. The paper is secured with tape. End faces for additional sealing are smeared with plasticine. A hole has been cut into the shell. A neck is made of plasticine around the hole. Epoxy resin was poured into the hole in the shell.
After curing epoxy resin, the shell has been removed. The rotor is clamped in the chuck drilling machine for further processing. Grinding was carried out with medium grit sandpaper.
There are 4 wires coming out of the motor. I found a working winding, and cut off the wires from the starting winding. I installed new bearings, because the old ones rotated a little tight. The bolts tightening the body are also new.
The rectifier is assembled on D242 diodes, the SOLAR controller, bought a few years ago on Ebay, is used as a charging controller.
Tests of the generator can be viewed on the video.
To charge the battery, 3-5 turns of the generator are enough. At the maximum speed of the drill, it was possible to squeeze out 273 Volts from the generator. Alas, sticking is decent, so it makes no sense to put such a generator on a windmill. Unless the windmill will be with a large propeller or gearbox.
The generator will stand on the ski lift. Field trials this winter.
