With your own hands from a motor. To spite scrap metal collectors: homemade products from a washing machine engine
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.

Hello! I came across your site while looking for the necessary mechanism to set our idea in motion! to what address Email You can send us our layout so they can look at it and tell you what kind of motor is needed to “revive” individual parts our model! Thank you very much in advance!
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.
The idea was born to make a mini fountain myself. The design of the fountain itself is a separate story, but this article will discuss how to make a pump for water circulation with your own hands. This topic is not new and has been described on the Internet more than once. I am just showing my implementation of this design. If anyone is too lazy to do it, then such pumps are sold on Aliexpress for around 400 rubles (price as of February 2016).
So let's get started. A bottle of nasal drops was used as a body. For those who are interested, I will write down the dimensions of some parts. So, inner diameter bubble 26.6 mm, depth 20 mm. A hole slightly larger than the diameter of the motor shaft is drilled in it on the back side, and a hole on the side for water outlet (4 mm in diameter). A tube is attached to it first with superglue and then with hot glue, through which the water will subsequently rise to the top of the fountain. Its diameter is 5 mm.
We also need a front cover. I drilled a 7 mm hole in the center. The entire body is ready.
A hole for the shaft is drilled in the base. The diameter of the base, you understand, should be smaller than the diameter of the body. I have about 25 mm. In fact, it is not needed at all and is used only for strength. The blades themselves can be seen in the photo. Made from the same box and cut to the diameter of the base. I glued everything together with superglue.
The engine will rotate the impeller. It was most likely taken out of some kind of toy. I don’t know its parameters, so I didn’t raise the voltage above 5 V. The main thing is that the engine is “faster”.
I tried another with a speed of 2500 rpm, so it raised the water column very low. Next you need to assemble everything and seal it well.
And now the tests. With a power supply of 3 V, the current consumption is 0.3 A in load mode (that is, immersed in water), at 5 V - 0.5 A. The height of the rise of the water column at 3 V is 45 cm (rounded down). In this mode, I left it in the water for an hour.
Passed the test fine. How long it will last is a good question that only time can answer. When powered by 5 volts, the water rises to a height of 80 cm. All this can be seen in the video.
Video
Separately regarding the noise. On land you can hear it quite well. Under water at 3 V in complete silence, the noise of the pump can be heard quite a bit. You can't hear him at all over the rushing water. So we can conclude that it is quite suitable for a fountain, and for others as well. I was with you SssaHeKkk.

Who would have thought that simplest inverter can be done 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'll show you how to convert electrical energy from 12 V DC to 220 V AC.
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 watch, 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.
Every day creating something with your own hands is becoming more and more popular. So why not create a special thing when everything is conducive to it? While women are diligently engaged in embroidery, sewing, knitting, quilling, men can only tinker, repair, and improve.
What to make from a motor?
Some parts of equipment that is broken and unsuitable for further use can be used at home. Quite often, men have the question of what can be made from a motor. In fact, there are a lot of options, the main thing is patience, the ability to work with technology and imagination.
As one option, you can make an excellent fan from a motor. People also make cars, helicopters and other interesting things from this part. All that is needed for full-fledged work (especially for beginners) is special electronic circuits and radio spare parts. Of course, you cannot do this without self-confidence and patience. It’s not a fact that everything will work out the first time, but if you try, the result will be for a long time please the master.
Helicopter from a motor
Having decided what can be made from a motor, it is worth thinking about how this thing is created. Stores sell special diagrams and spare parts that will help you cope with this difficult task and sort out the details. Sometimes you can’t even wrap your head around it, from a motor, but in reality everything is very simple, you just need to pay due attention to this matter.
So, to make a solid helicopter, you need to stock up the following materials: models with drawings, tools, motor, glue, power supply and control panel. If the case is already ready, then all that remains is to place the motor in it and connect it to the control panel. After this, you need to try to start the helicopter, and then it will become clear whether it is ready for use or has some problems that need to be fixed. If you have any difficulties connecting the wires, it is better to contact knowledgeable person, otherwise the parts may be damaged.
Men are often interested in what can be made from a motor, other than a helicopter. Let's consider another option.
A car made from a motor
Making a car from a motor is very simple. To do this, you need circuits and boards, which are sold in special stores. After purchasing everything you need, you can get down to business. There are two options for making a machine: you can make the body yourself or buy a ready-made one, which will make the master’s work easier. By purchasing a set, a person receives car parts, wheels, wiring, spare parts, a control panel and the motor itself (if there is none). It is worth noting that this will cost more than buying a regular ready-made machine, but you can also get great pleasure from the process itself.
Thus, it is completely obvious how to make a car out of a motor - you just need to purchase a ready-made housing and place the main part of the car there. Don’t forget about the control panel, which needs to be properly connected to the toy. As a result, the person will receive homemade typewriter, which will be cooler than any store-bought one. In addition, it can be improved, repainted and decorated as your heart desires.
In addition to all of the above, the beauty of making a car from a motor is that the child will certainly appreciate all the efforts of the parent, after which he will be immensely happy. You can build a miracle car together with your children. This is a very entertaining and interesting activity. Let's look at what else can be made from a motor.
Fan
Do-it-yourselfers (that’s what some men call themselves) are constantly trying to absorb as much new information as possible in order to make something new. It is not at all surprising that they are interested in things from the motor. To successfully carry out this operation you will need main detail structures, battery, sleeve, bulb and two old blanks.
First, blanks are used (cut along the radius), then the blades must be bent carefully using fire. For the next stage of work, a champagne cork is perfect, which needs to be pulled onto the axis of the motor. After this, you need to attach the blades to it and build a stand for the fan. The motor and all other parts will be glued to the latter. So light and interesting way make a fan.
Conclusion
So it's clear that you can make a lot of amazing things out of a motor. The main thing is desire and patience. In addition, you should not be distrustful of fantasy and intuition. No need to be afraid of ruining the product! We advise beginners to use old unnecessary things (as in the case of a fan). Experiment, you will succeed!
