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, the inner diameter of the bubble is 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. Underwater at 3V 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.

Discuss the article HOW TO MAKE A PUMP FROM A MOTOR

This video is for all beginning radio amateur experimenters who would like to make a simple mini motor from available radio components. Very good way to keep your child occupied and accustom him to technical knowledge. Be sure that your child will demonstrate his knowledge in physics lessons at school.

Let's assemble a simple electric motor

Let's repeat the old school experiment. What you need to prepare for homemade:
Battery 2a. Enameled wire with a cross section of 0.5 mm. Magnet. Two pins, stationery tape, plasticine. Tool. First, let's make a coil. We wind it from enameled wire. We make 6-7 turns around the battery. We fix the ends of the wire with knots. Now you need to properly clean the varnish on the reel. This is an important point - the performance of the engine depends on correct execution. One end is completely cleared of insulation. The other is on one side. This side must coincide with bottom coils.

We fix the pins on the battery with tape. We check the contacts with a tester. Install the magnet. In this case, weak. Therefore, you have to lift it closer to the coil. We fix the structure on the table with plasticine. You need to place the coil correctly. When it is installed, the stripped ends should touch the pin.

The operating principle of a simple micro motor

A magnetic field arises in the coil. The result is an electromagnet. Poles permanent magnet and the coils must be the same. That is, they must push off. The repulsive force turns the coil. One of the ends loses contact and the magnetic field disappears. By inertia the coil rotates. Contact appears again and the cycle repeats.

If the magnets are attracted, the engine will not spin. Therefore, one of the magnets will need to be turned over.

Let's start the engine. We can add a little practicality to this product. Let's attach a hypnotic coil to one end of the coil. Fascinating! You can make a famous thaumatrope with a bird in a cage.

A more advanced homemade engine for studying electromagnetic phenomena

Video “99%DIY”.


We will need wine stopper. First of all, we make a hole in the center. We cut out small planes on both sides. Place the knitting needle in the hole. Fix with superglue. We wrap electrical tape on the knitting needle. We install two pieces of copper wire inside the plug.

To create a mini motor you will need insulated thin copper wire. The master used a length of 5 m and a diameter of 0.4 mm. We wind in the 1st direction on the engine rotor. Remove the insulation from the winding terminals. We connect the wires to the contacts. We fix the winding with superglue. Give the contacts the following form. The engine rotor is ready.

Now let's make the body. This will require wooden base and two small bars in which we make holes. The bars are glued to the base. Install the engine rotor.

From two pieces of copper wire we will make brushes for a mini motor.

Why do you need two magnets? Glue onto small wooden blocks. Glue the blanks onto the base, leaving minimum clearance between magnets and winding. The electric motor is ready. Now let's move on to testing.

As you can see in the video, this miniature engine has a lot of play and does not have much power. But this is not important for such a homemade product; it is intended to study electromagnetic phenomena, which are often carried out at school superficially, without the use of special experiments. It is impossible to study a subject without visual and practical actions, especially when the issue concerns electricity. Here imagination is a weak helper.
However, as you may have also noticed, you can attach some kind of drive to the motor shaft. For example, the fan will work. When you have mastered this video lesson, you can proceed to more advanced motors. Use bearings to reduce friction. Then the efficiency of a device created by yourself will be able to compete with industrial products of this kind.

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 not a complete list of 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 of such an engine is the brushes that wear out, 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 garden tools, household knives and scissors. If you don’t already have one, buy it at any hardware store or make one sharpening machine from the washing machine. The most difficult part is how to attach the sanding 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 an asynchronous motor lying around, you will be surprised at how quiet the unit will be, even compared to 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. Finished model looks like this:

How to build a generator from an old washing machine

We continue to look at homemade items from a washing machine motor, and now it’s time for a 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 a 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 - additional equipment motor with a device that regulates speed. Without this additional module the circular saw 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 cutting boards up to 5 cm thick. How this homemade circular saw works:

What else can be made from a washing machine drum: original decor ideas

The drum with its correct perforation is a material for the manufacture of decorative objects. 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 will have to keep an eye on such a 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 outermost 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.

Make something useful out of useless children's toys or household appliances no problem for a master dreamer. And it’s good that many electrical appliances become outdated and break down. It makes no sense to send such things for repair - it’s easier to buy something new. And true “homemade people” are just waiting for this. They immediately have a whole bunch of ideas that require immediate implementation.

Second life of children's toys

There are times when a self-propelled toy breaks into pieces. Probably, in order to calm the child down, you urgently need to buy a new one? Not at all necessary. You just need to start the family process creative thinking. And to do this, remove the remaining usable parts from the broken machine along with the motor. Then collect all the toys in the house and choose the one that can be brought to life again. Probably, here you will need school knowledge in physics, chemistry and electrical engineering.

Repair of an old helicopter

Suddenly an old forgotten helicopter with an unusable engine and broken blades, which had long been lying on the mezzanine, caught my eye. He apparently waiting for my finest hour and now with pleasure showed off the blue and white sides with the half-erased inscription “USSR-0098”.

Such things must be handled carefully. The old man doesn't like fuss. You will have to carefully remove the remains of the large main screw by unscrewing several small screws. To get into the engine compartment, you need to remove the plastic battery box from below. The engine is held on by three bolts and, as expected, has two wires “plus” and “minus”, which are connected to the power switch through a microcircuit block. All this must be carefully unsoldered and unscrewed.

Having pulled the engine out to a white light, you need to inspect it and compare it with the motor from the car. The fact is that 250 -270 rpm is enough to create lift. and power 1 - 2 watts. The difference in engine characteristics turned out to be small. Then you can safely install a fresh engine on the helicopter. And then go to the model shop for a brand new main rotor. When everything is ready, the repaired rotorcraft is tested in the presence of the entire creative family.

Modern children's helicopter models are repaired using the same scheme. Only now they are radio-controlled, and therefore you will have to fork out money for a control panel, on which the rotor speed and the speed of the helicopter depend.

New engine for toy car

In order to make a small children's car, you need: wheels, the car body itself, wires, a control panel, various electronic boards and a motor. If you have all this goodness, they begin to create a model. There is no need to look for the engine, since it is already there. The car body itself can be make it yourself made of wood or plastic and decorated to your taste. It’s good for those craftsmen who have a small 3D printer in their home that can build any shape of model.

Often the machine is made quite simply. They take a long-abandoned small children's car with wheels, disassemble it down to the screw and try to automate it using a ready-made motor. The following are used: glue, electrical tape, small gears from watches, gearboxes from old models and much more. And people for whom such fun has become a real hobby often achieve great success in making homemade motors.

When several new models of children's cars have been made and tested, all that remains is to do something generally useful. It is necessary to design a fan that would freshen the air and inspire new ideas. For this you need just a few items that are at hand. Namely:

• a motor from a children's toy (you can't go anywhere without it);
• CD discs, 6-7 pieces;
• plastic bottle cap;
• cardboard tube approximately 10 cm high and 3 - 4 cm in diameter;
• switch;
• glue.

Manufacturing begins by cutting the disk into 8 equal parts from the edge to the center, not reaching approximately 1.5 cm from the hole. Then the resulting sections must be turned with one edge outward to form blades. The manufactured disk is placed on a plug, inside of which a hole is made for mounting on the motor.

Now they are making the leg and stand. A cardboard tube can easily pass for a leg. Wires and batteries will be hidden inside it. The remaining few disks can serve as an excellent stand. All this is glued well and painted in different shades. The fan is ready for operation.

Motorized ship

In order for the child not to hang out at the computer for days, he needs to be gradually accustomed to making various and interesting things that he can make with his own hands. Spring is coming, the streams will run, and you will need a small boat that will symbolize the coming long-awaited warmth.

Required materials The child will find it in his room. Here you need:

• AA batteries 3 pieces;
• polystyrene foam, electrical tape, glue;
• motor from a CD drive or toy;
• plastic cover from a lemonade bottle;
• two pieces of plastic and iron washers.

The first step is to make a propeller. Slots for the blades are prepared in the cork. Flat ice cream sticks are the finished blades of the future boat. Then a hole is made in the plug to fit this screw onto the motor. All this is well glued. The power plant is ready.

Next, the shape of the ship is cut out of the foam. The front part of the boat is made triangular; a place is prepared at the stern for propeller with a motor, and in the middle you need a recess for batteries. Everything is connected and glued. They carry out tests in the bathroom and look forward to the first spring puddles.

Glider car

This is the most exciting toy created and tested by a child. On the ground, such a machine moves on wheels, and on the water on a special boat. It is made in 2 - 3 hours.

Required materials:

Do power plant. It is an engine with a propeller. The blades are cut using the neck of the bottle.

It should look like a rose. You can see from the photo that it is then screwed onto a plug attached to the motor.

Then they do chassis. To do this, use a skewer. They put plugs on it that serve as wheels. They attach everything to a square bottle, inside of which the batteries are placed. Connect with wires according to electrical diagram. The glider is ready. If desired, you can replace the plastic propeller with a more rigid one. Then the driving performance of such a car will be appreciated not only by the designer himself, but also by his friends.

Crawling robot

Manufacturing the robot takes only a few hours. It's not quite the robot people imagine. He does not walk, does not swim, but crawls chaotically smooth surface. This effect is created due to the unbalanced rotation of the motor rotor. For real cars this leads to a tragic accident, but here it only causes a smile.

So, to create a robot you need a motor and a battery. A small oblong piece of foam plastic or foam cardboard is placed on the engine axis and glued. This serves as a destabilizer. To the very tip of it attach a decorative light element.

A battery is installed on top of the motor and covered with various interesting details. They make his legs out of toothbrushes, his eyes out of balls, decorate him with colored wire or paper clips, and so on. When turned on, the engine vibrates significantly, which causes the toy to crawl chaotically.

Other ideas

In addition to all of the above, motors are used in homemade products such as mini drills and drills. Such devices do not require unnecessary parts. They have one task - to rotate the fixed drill.

To do this, select a collet or regular chuck on the motor axis that will clamp a small drill. Then solder the wires from the engine to the batteries through the switch. When the assembled device has successfully worked, it is placed in an antiperspirant case or some other case that is most suitable for a motor with batteries. This whole little device fits in the palm of your hand. The switch is always located under the thumb.

Such devices are necessary for radio amateurs for drilling holes V printed circuit boards. They can also be used by cabinetmakers who engage in fine volumetric wood carving. Only instead of a drill, they insert a finger micro-mill for sampling and grinding hard-to-reach places.

As you can see, with a little imagination and diligence, a child, with the help of his parents, can create truly original toys and other useful things.
