Who would have thought that the simplest inverter could be made without the use of transistors, microcircuits and complex circuits. Last time I showed . As it turns out, this is not the only way to build an inverter. I will show you how you can convert electrical energy from a constant voltage of 12 V to 220 V alternating current.
What will you need?
Step-up transformer. Naturally, before it worked as a buck, but we will use it in reverse. Such transformers can be found in receivers, electronic watches, and old tape recorders.
Inverter assembly
In fact, our circuit consists of only three parts connected in series to each other. This is a transformer connected to the circuit with a low-resistance winding (the high-resistance winding is the output of the inverter). Batteries - batteries or accumulators. And a switching element, in the role of which an electric motor will be used, which can be removed from broken children's toys.
Here's the motor itself. You can’t just insert it into the circuit - it won’t perform switching. We need to refine it.
To do this, we disassemble the motor.
We remove the back part, first bending the holders.
The anchor needs to be improved. This consists of disconnecting one winding from the contacts. To do this, we cut off the wires of any one winding.
We assemble the motor.
After such modification, the motor will not be able to rotate fully, since one winding will be turned off. But if you start it by hand, then the motor has enough power to maintain rotation. And the absence of one winding will periodically break the power circuit between the power elements and the transformer, where the motor is connected in series.
We connect it to the circuit.
We connect a multimeter to the output of the transformer. Then turn on the power. It happens that the motor starts on its own, but usually it doesn’t. Then we start the shaft by hand, turning it lightly.
The inverter is working! The multimeter readings jump from zero to about 250 V. This is normal, since this is a technical inverter for powering primitive devices.
We try to connect the charger. Everything works fine - the phone is charging.
We connect the light bulb - the lamp shines.
Of course, there is no need to talk about the quality of the converted energy, but in complex life situations such a craft may well come in handy.

Scrap metal collectors will be happy to take your old washing machine. But don't rush to please them. You won't get much money for scrap, but if you approach this issue wisely, you can get a lot of useful things for household. Homemade engine from washing machine They will help you quickly de-feather a bird, cut up pet food, mow the lawn, smoke fish and meat. And this is far from full list what can be made from a washing machine. Today in the editorial review of the site detailed instructions, how to give the “heart of iron” from a washing machine a new life.
Parts from a washing machine are a material for many useful homemade products
If you are planning to make homemade products from a used engine, you need to figure out what it is and what it is capable of. In you can find three types of motors: asynchronous, brushless and commutated. Let's take a closer look at them:
- Asynchronous– can be two-phase or three-phase. Two-phase engines are found in older Soviet-made models. More modern machines are equipped with three-phase. The design of such an engine is extremely simple; it can reach speeds of up to 2800 rpm. The working engine removed from the machine just needs to be lubricated - and it is ready for new exploits.
- Collector– you will find this type of motor in the design of most household appliances. Such devices can operate from direct and alternating current, have compact dimensions and a controlled speed. The only drawback This engine has washable brushes, but these parts can be replaced if necessary.
- Brushless Direct Drive– the most modern engine from the Korean manufacturer. You will find it in modern washing machines from LG and Samsung.
Now that you can determine the type of motor, all that remains is to decide where you can use the motor from the washing machine.
We properly disassemble and decide what can be made from parts of an old washing machine
Disassembling a washing machine is a leisurely task. After working with water, a salt build-up may remain on the parts; it must be carefully removed so as not to damage the parts during removal. What can be made from an old washing machine? A motor will be useful for homemade projects - it will become the basis for many devices. The drum will also come into play. It is usually made of stainless steel. All pipes must be disconnected from the drum. A loading hatch may also be useful. In addition to these parts, do not rush to throw away springs, counterweights and body parts.
How to make a sharpener or grinding device from a washing machine engine
A sharpener is one of the most popular tools for the home. With its help you can sharpen gardening Tools, household knives and scissors. If you don’t already have one, buy it at any hardware store or make one grinder from the washing machine. Most difficult moment– how to attach the emery wheel to the motor. The easiest way is to buy a ready-made flange. It looks something like this.
You can machine a flange from metal pipe suitable diameter, most often a tube with a cross section of 32 mm is suitable. You need to cut a piece 15 centimeters long from it, this is quite enough to fix the emery. The flange is secured to the motor shaft by welding or a through bolt. The video describes in detail how a homemade washing machine sharpener works:
Making a wood lathe from a washing machine
What else can you do with the washing machine motor? One popular idea is a wood lathe. Let's look at the step-by-step process.
| Illustration | Description of action |
|---|---|
 | To firmly fix the engine on the workbench, make fasteners from a metal angle. To do this, drill holes for fixing to the motor legs and table. |
 | To fasten a wooden part, you will need a flange fixed to the motor shaft, and these are the studs made from ordinary bolts with cut off heads. Screw these pins into the base. You will need 3 studs. |
 | The motor is fixed to the table with self-tapping screws and to the metal part with bolts. |
 | The opposite end of the wooden part is attached with such a device. It consists of a screw with a loop, two wooden stands perpendicularly fixed to the corners. |
 | This wooden part must be movable so that different workpieces can be used. For mobility, it is mounted on a threaded stud with bolts. |
 | To control the motor you will need a power supply. You can use one of the computer units. You will need to install switches to adjust the rotation speed. |
 | How to connect a motor to a power supply in animation. |
 | To guide your tools, make a tool rest. It consists of two wooden parts and a metal corner. All parts are movable due to fastening with one bolt. |
 | The lower part of the tool rest is rigidly fixed on the workbench using self-tapping screws and corners. |
 | The workpiece is fixed on the machine on both sides: on the left - on studs, on the right - on a bolt with a handle. To fix it in the workpiece, you need to drill the corresponding holes. |
 | To work, you will need sharpened tools - cutters. |
 | Final sanding of the workpiece is done using a strip of sandpaper. |
How to make a simple feather removal machine for home use from a washing machine with your own hands
The time of slaughtering a bird is a troublesome stage. This is usually done in the fall, when the ducks and broilers have reached the desired weight, and it is no longer profitable to keep them in the winter. You need to pluck several dozen or even hundreds of carcasses very quickly. You can get rid of hard labor with the help of a feather removal machine, and it’s easy to do everything from the same parts of the washing machine.
The device does not require disassembling the washing machine. It is especially convenient to use machines with vertical loading. You just need to fix the beats in the drum so that they point inward. Before plucking, the chicken carcass must be scalded with boiling water and then simply thrown into a rotating drum. Here's what happens:
Important! To prevent water from getting on the engine of the feather removal machine, you need to protect it with a plastic casing.
And the last point - the feather removal device must be firmly fixed, since the vibration when loading the carcass will be very strong.
Lawnmower from a used motor
We continue to look for the answer to the question of where we can use the motor from an automatic washing machine. Another original idea is making. Sufficient for a small area electric model connected to a power source with a cord. The design of such a unit is very simple. You will need to make a platform on four wheels with a small diameter.
The engine is fixed on top of the platform, the shaft is threaded into the hole below, and the knife is attached to it. All that remains is to attach handles and a lever to the cart to turn the power on and off. If you have some asynchronous motor, you will be surprised how silent the unit will be, even in comparison with factory models.
Advice! To prevent grass from wrapping around the knives, you need to bend them slightly cutting edges down.

Animal feed cutter
For a rural resident, a feed cutter is a very important device in the household. And this unit is easy to make from. What can be used: a drum and a motor.
For a feed cutter, you will need to make a housing in which a drum with holes sharpened for cutting and a lid for pressing will be mounted. The connection between the rotating drum and the motor is carried out through a drive. The finished model looks like this:
How to build a generator from an old washing machine
We continue to look at homemade products from a washing machine motor, and the turn has come to the generator. You won't be able to assemble a powerful device, but in the event of an emergency shutdown, you can be well prepared. To turn the engine into a generator, you will have to disassemble it and partially cut off the core. In the remaining part of the core you need to make grooves for neodymium magnets.
The gaps between the magnets are filled cold welding. To operate the device, the kit must include a motorcycle battery, a rectifier and a charge controller. Details of the work in the video:
Homemade concrete mixer
If you have started a small renovation that requires, for example, plastering the walls, a concrete mixer will come in handy. Once again, washing machine parts will come in handy.
As a container for concrete, you can use the same drum with pre-sealed holes for draining water. It is best to use parts from a front-loading machine; there will be almost nothing to redo. To strengthen the body, use metal corner, and for convenient movement of the concrete mixer, equip it with wheels. The main difficulty in the design is the manufacture of a “swing” for the correct tilt and subsequent pouring of concrete. How to do it correctly in the video:
Homemade products from a washing machine engine: circular saw
You will be surprised, but a circular machine can also be built based on the motor from a washing machine. Important point in this matter - optional equipment motor with a device that regulates speed. Without this additional module, the circular machine will work unevenly and simply will not cope with the task. Device assembly diagram:
The principle of operation of the device is simple: the engine drives a shaft on which a small pulley is mounted. From the small pulley there is a drive belt to a large pulley with a circular saw.
Important! When working with a homemade circular saw, take care of your hands. All structural parts must be firmly fixed.
The resulting unit will not be very powerful, so it can only be used for dissolving boards up to 5 cm thick. How does this work? homemade circular:
What else can be made from a washing machine drum: original decor ideas
The drum with its correct perforation is the material for manufacturing decorative items. Here are some interesting ideas.
Bedside tables and tables. Drums with doors from top-loading machines can be used to hide small items.
Making a barbecue from a drum from a washing machine, photo examples
- a temporary product. Sooner or later it burns out and requires replacement. You can buy a new one each time or use improvised material, for example, a drum from a washing machine. Making this craft from a washing machine drum takes a couple of minutes. The beauty is that oxygen easily enters the perforated container, which causes active combustion.
The metal of the drum can withstand a couple of seasons. Do it for him convenient stand, so that you don’t have to bend over, and you’re done. Standard length skewers will fit comfortably on a small roasting pan. If necessary, you can lightly weld a couple of guides.
How to make a good smokehouse from a washing machine drum
The icing on the cake in our question is. Fragrant smoked meat, lard and fish - what could be better for the table? If you have a tank from a top-loading machine lying around in your shed or garage, consider it a done deal.
It is necessary to cut a hole in the bottom of the tank for the firebox, and weld fasteners inside for hanging food. All that remains is to install the tank on the fireplace, hang the fish or lard, cover the top of the tank with a lid and light the sawdust.
It is important that the fuel under the smokehouse smolders and does not burn. It is better to place such a device away from home.
Important! You'll have to keep an eye on this smokehouse. It should not be left for a long time, the fire may flare up, and instead of a smoked product you will get a burnt product.
In this material we will present to your attention a review of a video on making a machine with a motor.
So, we will need:
- 3-volt motor from a cassette player;
- 3 AA batteries;
- metal washer;
- electrical tape;
- toy car.
At the very beginning, we note that the author advises using a machine that has a mechanism that moves it forward after rolling back.
We disassemble the machine and cut out the mechanism mentioned above.
We take the gear out of the mechanism and glue it to the motor with a glue gun.
There should be another small gear on the shaft. The motor needs to be glued so that the large gear touches the small one.
We connect 3 batteries in series so that the minus of the middle battery is connected to the pluses of the outer ones. Contacts can be connected using metal washers. The batteries can be connected to each other with electrical tape.
We assemble the machine body, not forgetting to remove the wires coming from the motor.
We connect the negative wire from the motor to the negative on the outermost battery.
Next, take another wire and connect it to the positive contact of the second extreme battery.
We install the battery pack on the roof of the car.
In order for the motor to work and the machine to move, you need to connect the positive wire coming from the motor with the wire that is connected to the positive contact of the battery.
Different motors have different numbers of revolutions per volt and therefore are best matched to a specific toy or specific use - those that are suitable for use as a wheel motor will not be suitable for use with propeller and vice versa!
The first is a small motor with a diameter of 2.4 cm, it is great for use in homemade toys to rotate the wheels.

Here is an example of making an airboat using such an electric motor with a propeller.
As you can see, you can make such a simple airboat in 20-30 minutes.
The third motor is equipped with a gearbox and can be used to mechanize toys with large wheels.
Buy an electric motor with a gearbox for a wheel Can .
The reduction gearbox is made of metal; it increases the torque power on the shaft and allows you to install this electric motor directly on the toy wheel.
The electrified toy will be slow, but will be able to carry fairly heavy loads and climb hills with them.
Set of 5 small electric motors.
