Rubbish in business! Homemade products from the engine and drum of a washing machine: from idea to implementation. Homemade products from the engine from the washing machine (video selection, photos, diagrams) Wood milling machine from the washing machine

Any washing machines become unusable after a certain period of time, and most often they are simply sent to a landfill. But some details from it can be given a second life. For example, an engine from an old washing machine that has failed can become the basis for a new home-made fixture or tool. There are many different ways to use it for the benefit of the household. True, it all depends on the imagination and skill of the home master.

Types of engines

The type of electric motor chosen for homemade depends on the age and model of the washing machine. For example, if it was an old washing machine from Soviet times, then it most likely had a reliable asynchronous electric motor installed on it. Such a motor from a washing machine has a power of 180 W, has excellent torque indicators and is the most convenient motor for homemade products. Also in the hands of the master may be a two-speed electric motor, a collector motor or an engine from a modern SM of any model and class.

asynchronous motor

Asynchronous electric motors used for washing units can be with two or three phases. But since about 2000, the production of motors with two phases has practically ceased, and they have been replaced by more modern three-phase ones, with frequency control of the rotation speed.

Such a device consists of a stator, which is a fixed element of the electric motor and a rotor that drives the drum of the device.

The advantage of this device is:

• In a simple design.
• Ease of maintenance.
• In low noise level.
• At a low cost.

The disadvantages include large dimensions, low efficiency, the complexity of the electrical circuit and its control. Such electric motors can still sometimes be found in old, inexpensive models of washing machines. They are not used in powerful modern devices.

Collector motor

Such electric drives have been used since the 90s and are considered almost universal due to the ability to connect them not only to AC, but also to DC voltage,

The electric motor has an aluminum housing in which a collector rotor, a stator and a block with contact brushes are built.

Advantages of a collector motor:

• Small sizes.
• Smooth speed control by increasing or decreasing voltage.
• Ability to work with different types of voltage.
• There is no binding to the frequency of the electrical network.

The disadvantage is expressed in the frequent change of contact brushes and a short service life.

inverter drive

This is a direct drive motor, which is also called an inverter motor. It does not have a collector rotor. Developed by the Korean company LG and refers to the latest technology. The mass production of inverter drive motors began in mid-2005. With a reliable, durable and simple design, they firmly hold the leading position in the electric drive market.

The advantages of an inverter drive include:

• Compactness.
• Low machine vibration.
• High efficiency
• Lack of contact brushes and belt drive.
• Virtually silent operation.

The disadvantage of inverter motors in the form of a complex electronic control circuit is more likely to concern manufacturers than consumers,

Connection and launch

When dismantling the electric motor from the washing unit, it is recommended to make special marks on all its wires. These actions will later help to connect the motor directly to the electrical network (this is especially true for asynchronous electric motors from old washing machines, where starting capacitors are required). Other types of motors also have their own characteristics.

Therefore, for the correct connection of each type of electric motor, it is best to search for information on the Internet or use special reference literature for this. And if during dismantling all the contacts were marked, then starting the motor from the washing device will not be difficult. To do this, you will simply need to follow the instructions for connecting a certain type of engine to the network and follow the safety rules.

The second life of the electric motor

From an old, broken washing machine, it is possible to make many homemade products for household needs. Many of its elements are suitable for this, including the body, drum, covers, etc. But most often, units are made for use in household purposes, home workshops or garages, using a motor.

You can use the electric motor from the washing unit, for example, by making a home-made juicer for the kitchen, a vibrating table for the workshop, as well as making many other useful devices and devices that can greatly simplify some types of work for the home master.

Grinder

For the manufacture of a grinding machine, a high-power motor is not required, and in terms of the number of revolutions, any electric motor from an old washing machine can be suitable.

To build a machine, you need to prepare a base plate for it from cutting a thick wooden board and fix an electric motor and a switch on it, taken from the same washing machine. For fastening, you can use metal brackets.

Next, cut the thread and fix the adapter-nozzle on the shaft for attaching the grinding wheel. In the kit for the nozzle, you can prepare an adapter with a neck for a cutting abrasive wheel. Then you get a cutting machine that can cut plastic pipes, as well as fittings, a metal sheet or a corner.

The result can be a compact, portable and almost universal grinding and cutting machine, the manufacture of which does not require the use of electric welding.

Forage cutter and grain crusher

Another homemade product to help those who are engaged in agriculture can be made from an electric motor removed from washing equipment. It is a grain crusher and feed cutter in one piece.

Converting a laundry machine into a food cutter does not require much effort. To do this, you need only the body of the machine with the top load of linen and the electric motor itself. The case can be purchased for a penny at points where scrap metal is accepted or searched at a landfill.

The manufacturing technology of the feed cutting unit itself will be as follows:

A device made on its own will cost much less and will work almost as well as a factory-made one.

Making a mortar mixer

For those who are going to build or make repairs in the future, the motor from the washer can be useful for the manufacture of a full-fledged mortar mixer, which can facilitate the construction process and at the same time save significant funds. This will be especially beneficial for residents of rural areas, where the construction process practically does not end.

The manufacturing process of the mortar mixer looks something like this:

This design is convenient because it works like a swing, and the prepared solution can be easily poured out of the mixer by simply tilting the tank.

To mix the solution, it is best to use a washing tank from a top-loading machine. Its capacity is just enough to mix several buckets of mortar.

The activator is removed from the tank and the water drain hole is tightly closed. Instead of an activator, a shaft is installed on which a steel strip with sheet metal blades is attached inside the tank.

The tank is laid and fixed to a movable frame welded to the mixer base pipe. Outside, an electric motor connected to the shaft is fixed to its bottom. To do this, two holes are drilled in the bottom of the tank according to the size of those on the motor housing, after which the tank is rigidly bolted to the barrel.

After that, it remains only to connect the electric motor and test the operation of the mortar mixer.

How to make a lawn mower

A homemade lawn mower is one of the options for using an electric motor from a decommissioned washing unit. This tool is useful to owners who own a personal plot or a summer cottage. At the same time, homemade does not need to purchase any additional spare parts, which can always be found in a barn or in a landfill.

A homemade lawn mower with a motor from a washing machine can be made in this way:

This completes the manufacture of a homemade lawn mower, and it is ready to go.

The scope of use of electric motors from washing machines is very wide. A lot of homemade material can be freely found on the Internet - on thematic sites or forums.

Would you like to have your own lathe and milling machine? It is not necessary to go to the store for a purchase, you can make a homemade lathe from the engine of a washing machine.

In this article, you will learn how to make the main parts of the device, assemble them and connect the machine.

Instructions: how to make a lathe from a washing machine engine

Consider how to make a lathe for woodworking from the engine of an automatic washing machine. With it, you can cut workpieces, drill holes, grind.

The machine has the main parts and components:

• headstock;
• tailstock;
• handyman;
• frame.

For operation, an asynchronous electric motor from a washing machine can be used. Two speeds - at 400 and 3000 rpm - will be enough.

Now let's take a closer look at how to make each node and assemble a one-piece structure with your own hands.

Headstock

The operating parameters of the device, the size of the workpieces will depend on the device of the headstock, as well as the power of the motor. The spindle must be reliable because it is subjected to radial and axial loads when it is pressed by the tailstock.

Proceed like this:

With the manufacture of the headstock finished.

tailstock

One of the main elements that allows you to press a wooden blank to the headstock. The reliability of the tailstock fastening depends on how high-quality and safe the work will be. The dimensions of the parts to be machined will depend on the length of the retractable headstock element.

Get to work:

• Take two channels 140 mm wide. Connect them using four metal strips.
• Weld two partitions to the bottom of the body using a welding machine.
• In the partitions, fix two bushings measuring 14x20 mm. One sleeve is welded, and the other is fixed with two screws.
• The shaft is made for bushings: diameter 20 mm, edges 14 mm, center shifted by 2 mm. Once installed, the shaft should go down and up as it rotates. There should be a gap of 4 mm at the top and bottom while driving to allow the headstock to be clamped and released.
• Take two pieces of pipe 30-40 mm long and 21-23 mm in diameter. Weld them to the heads of the M12 bolts. Weld the tubes together by connecting with a wire 3-4 mm thick.
• Attach a handle to the end of the shaft that comes out of the bushing.

Assemble the device as shown in the photo and attach the bolts to the plate.

It must be tightened with nuts so that the structure is fixed on the support when you turn the handle away from you. When moving towards itself, it should lower and move along the support. This will allow you to quickly rebuild the machine for processing different parts.

Now you need to make a quill with a rotating center:

1. Take three straight bearings and one thrust.
2. Make the quill from a thick pipe with a square section and dimensions of 30x30 mm. Mill edges up to 29x29 mm. Fasten it with an M12 nut at one end, and with a 12 mm long rod at the other. Press three bearings onto the rod.
3. Make a body for the quill from a pipe with a square section of 29x29 mm. At one end, the body is completely closed, leaving only the center hole. On the other hand, a cut is provided where a nut with an eye is welded. Thus, by inserting the bolt into the eye nut, you can secure the quill.
4. Take a hairpin, where there should be an M12 thread on one end and an M8 thread on the other. A flywheel is screwed onto the end of the M8 and an M8 nut is fixed.
5. Weld two pieces of the corner to the quill body and fasten it to the tailstock.
6. Adjust the tailstock accordingly so that its center axis, while rotating, coincides with the axis of the headstock spindle.

handcuff

From the correct manufacture of the handpiece depends on how safe and convenient the device will be in operation. In order for the handbrake to be easily rebuilt and securely fastened, you need to make an eccentric clamp.

• Take the shock absorber rod.
• Make two bushings with sides. Their diameter should be 26 mm. Make holes in them with a size of 14 and 10 mm. They should be offset 2 mm from the center.
  
  
• Drill threaded holes from the larger end to secure the bushings to the axle with screws.
  
  
• Take a piece of pipe so that its diameter is slightly larger than the stem. A bar with an M12 thread is welded to it.
  
  
• For the manufacture of the case, take a channel with a size of 80x40 mm. Inside, weld two partitions, make holes in them. Weld bushings with a diameter of 26.5 mm and a length of 19 mm into the holes.
• The design must have backlash so that the stem can rotate.
  
  
• To fix the handpiece, weld a piece of pipe to the stem. Cut it at the end and weld the nut and sleeve on both sides. When screwing in, the bolt should clamp the handpiece.
  
  

From the motor of the washing machine you need to make a starting device. Therefore, the connection is made according to the scheme.

Be sure to make a casing for the engine. You can make it from pieces of laminate. Install a speed controller on the body, which will allow you to perform work of varying complexity.

How to make a milling machine

You can make a milling machine with an engine from a washing machine in the same way as a lathe. Use the front and tailstock in the design. Processing of parts can be performed using a cutter, chisel or milling cutter.

Homemade products from the washing machine motor are reliable and easy to use. The main thing is the preparation of detailed drawings, since in these designs everything must be accurate.

Use a homemade lathe and milling machine for woodworking and other household needs.

Even in a professional workshop, even in an ordinary garage, it is often required for some household needs to accurately drill several holes in metal, wood and other materials. An ordinary household drill may not be suitable for this, especially when increased accuracy is needed. A drilling machine from a washing machine, or rather from a washing machine engine, which you can do yourself, can come to the rescue. It will cost you very little. It is about the manufacture of such a machine that will be discussed in the article.

Main details

Before assembling a drilling machine using an engine from a washing machine, it is necessary to clearly understand the safety rules, both during assembly and during the subsequent operation of such equipment.

Remember! Working with a homemade drilling machine can be dangerous to life and health! Be extremely careful and do not forget that in the absence of the necessary skills, you should not undertake the manufacture of such units. We do not encourage everyone to make and use drilling machines and provide this information for informational purposes only.

So, what parts are needed to make a drilling machine? Conventionally, all the necessary parts of the machine can be divided into 3 groups: the engine and the drive mechanism, the frame and the movement mechanism of the drill in the vertical plane, and the electronic filling. The first group includes:

Details of the second group:

• steel corner 50 mm;
• steel beam 30x60x30 cm;
• square sheet of metal 40x40 cm;
• steel staples;
• old steering rack from VAZ G8;
• fasteners;
• drill shaft;
• bearings 6003 2RS;
• bearings 8103;
• drill chuck;
• homemade pinwheel of three studs welded together.

And finally, the details of the third group are represented by electronic filling, which will control the engine speed so that the drilling machine works stably without failures. The easiest way is to use a ready-made microcircuitTDA 1085, although there may be other options.

Machine mechanism

Making a drilling machine from a washing machine engine and other motors, do-it-yourselfers have long realized that it is easier to achieve what they want using as many standard standard parts as possible. Let this make the structure a little more expensive, but it will be more reliable and last longer, and most importantly, it will be easier to assemble it. A vivid example is the use of a VAZ steering rack in the manufacture of a moving mechanism. In essence, this is a movable mechanism, it remains only to come up with a worthy frame for it.

In the picture above you see the initial stage of manufacturing the mechanism of the drilling machine. We reliably weld the steel beam to the metal sheet, thus creating a reliable and strong frame. To a steel beam located vertically, we fasten the steering rack from the VAZ 2108 to the bolts with brackets as shown in the figure.

In this case, we immediately had problems attaching the turntable, and we had to cut a small notch in the base of the steel beam.

Let's move on to a more difficult stage, namely the manufacture of the basis of the movable mechanism and parts of the mechanism itself, without which the drilling machine will not be able to function. Separately, this part of the machine is shown in the figure above.

1. From the scraps of the corner, it is necessary to make a rectangular frame with an allowance on one side for fasteners. These large bolts are fitted with bearings, thanks to which this critical structural element will move up and down the beam like on rails.
2. We weld another piece of corner to the frame on the side, in which you need to drill a hole for the bolts. They frame is screwed to the movable steering rack.
3. We weld a square profile from two pieces of a corner, into the body of which we will insert a drill shaft with bearings. Accordingly, on the one hand, a cartridge will be dressed on the shaft, and on the other, a pulley.

Now we just have to screw the part placed in the picture above to the steering rack. It turned out a solid base, which already outwardly resembles a drilling machine.

Motor and its connection

Connection, verification, and we have repeatedly considered in the framework of other publications, so we will not dwell on this. We only note that before installing the engine on a drilling machine, it would be nice to check it for performance.

So, from the corners we weld the frame, on which we put the engine and fasten this structure on the side to the movable mechanism of the drilling machine. We first put a pulley on the motor shaft.

Now it remains for us to pull the drive belt between the pulleys, connect the engine to the TDA 1085 microcircuit board, power the machine from the household electrical network and you can test the new drilling machine that you managed to make with great difficulty. Load drills of different diameters into the chuck and see how the drilling machine copes with making holes in thick sheets of metal - a mesmerizing sight.

Important! When connecting the microcircuit to the engine, do not forget to protect it with a plastic case, you never know what can fly into it in the workshop during operation.

In conclusion, we note that it is quite possible to make a drilling machine using a motor from a used washing machine, if you have the right hands, a great desire and a workshop with the appropriate equipment. Such a machine "will cost three kopecks, and will work for three rubles." Good luck!

In some situations, it is cheaper to purchase a new product than to restore failed household appliances. However, a prudent person will receive additional benefits by using functional components for their intended purpose. This publication presents homemade products from the engine from a washing machine .. And video clips will help to more accurately reproduce homemade craftsmen and get useful products quickly and at no extra cost.

What is the engine from an old washing machine suitable for?

First you need to clarify the real capabilities of the existing power unit. In household appliances of the Soviet period, fairly reliable asynchronous electric motors (180–220 W) were installed. They were connected to two-phase AC networks. Previously, structures were created in a collapsible version. Therefore, in the event of a breakdown, repair does not cause excessive difficulties. The only exception is winding damage. Modern models are characterized by increased power (up to 340 W).

Since the late 90s of the last century, such simple engines have not been used. Instead of asynchronous, collector units are more often used. They are smaller and weigh less. In the corresponding modifications, the following possibilities are provided:

• DC power connections;
• smooth speed control.

To supply current to the rotor part, graphite rods with spring pushers are used. These parts must be replaced periodically. The power of collector-type electric motors ranges from 340 to 780 W at a speed of rotation of the working shaft in the range of 11400–15200 rpm.

The photo shows the power unit, which was first used by the engineers of the famous South Korean brand LG. It is often called an inverter, since it is assumed that the speed can be smoothly adjusted (up to 2 thousand per minute) using an external control device. The power of such units exceeds 500 W, which allows you to connect it directly to the drum shaft without a special belt drive. The following parameters and features of the motor from the washing machine determine where this power unit can be used:

• power;
• speed of rotation of the working shaft;
• dimensions;
• power supply and control circuit.

Note! More attentive people pay attention to maintainability, reliability, resistance to external influences. They study the opinion of experts in specialized forums, official manufacturers' guarantees.

What can be done from an old washing machine: examples of work with comments

The information below will help you realize different projects based on the respective power unit. Here are the current homemade products from the motor from the washing machine, which performed well during practical tests. Some projects come with step-by-step instructions with detailed explanations of the build process.

How to make a grinder or sharpener from a washing machine engine

Illustration	Action Description
	First of all, we will determine which interchangeable nozzles will be used in practice. The features of processing processes are of significant importance: the duration of cycles, the hardness of the material of the workpieces, etc.
	In this version, the author uses grinding discs with a diameter of 200 mm with an adhesive layer on the non-working side. He picked up a nozzle of approximately the same size from a “grinder” (175 mm) with a threaded connection in the central part.
	To implement the plans, an old washing machine engine was found, which rotates the anchor at a speed of up to 1500 rpm. In the photo, the arrow indicates the starting relay, mounted on the case. Food - from the alternating current network 220 V.
	A special nozzle has been created on a lathe. It is attached to the 14mm shaft with a screw. A threaded rod is welded to the end of the part, which corresponds to the connecting node of the adapter.
	During practical tests, it became clear that the initial rotation does not correspond to the direction of the thread. This means that when performing work operations, the nozzle will unscrew. The author did not use a special electrical circuit, but swapped the housing covers along with the bearing.
	For reliable fastening of the power unit, a special bed was created from steel corners. Welded joints cleaned. At the final stage, the product is covered sequentially with a primer for metal and paint.
	Using screws, a table (1) equipped with a rotating frame is connected to the frame. A support rod (2) with height adjustment is installed in the center. With its help, the exact angle necessary for working with workpieces is set.
	The assembly confirmed the accuracy of the calculation and individual parts. To eliminate errors, it is necessary to prepare a set of drawings in advance. It is not necessary to comply with engineering GOSTs. However, it is necessary to carefully understand the features of each component of the structure, note the dimensions and landing dimensions.
	A practical test shows the good functionality of the new machine. Power is quite enough for processing duralumin blanks. An additional plus is the quiet operation of the washing machine engine.
	For the collection and disposal of waste, a special box was made with an outlet pipe for connecting a vacuum cleaner. It is installed at the bottom of the bed under the working area.

Note! According to this algorithm, it is easy to create a high-quality grinding machine from a washing machine. To increase safety, it is necessary to use personal protective equipment during processing. A transparent polymer shield covering the work area is also useful.

Wood lathe

It is not too difficult to create a sharpener with your own hands from a washing machine. However, the following example demonstrates the relative ease of manufacturing more complex equipment.

Since an asynchronous motor from the Vyatka washing machine is used, a capacitor is installed in the power circuit. The armature of this power unit rotates at a speed of 400/3000 revolutions per minute. To set the axle parallel to the frame parts, washers of the appropriate thickness are selected.

The picture highlights important details:

1. These rods (1) must have sufficient strength, since the movement of the equipment around the site is carried out manually.
2. The engine switch from the washing machine is installed near the handle for the convenience of the user. For connection use a wire (2) with high-quality insulation. They provide good tightness of electrical components so as not to create emergency situations in conditions of high humidity.
3. Belt drive (3) reduces vibration. By changing the size of the pulleys, they select the optimal speed of rotation of the knives.
4. Such nodes (4) are used to adjust the clearance, the height of the lawn mowing.
5. Large wheels (5) are useful for overcoming obstacles on the land.

With the help of our online magazine, it is easy to draw the right conclusion about what to do with the old washing machine after the end of the intended use of the technique.

The video demonstrates the principle of operation and features of the picking machine:

A wood lathe is the dream of many craftsmen involved in the manufacture of crafts. For those who do not have free money, it is difficult to achieve, therefore it can remain unrealized for a long time. Although you can search the Internet for ideas for making a machine from improvised materials, and the desired will become a reality. As a result, it will be possible to implement previously conceived projects.

You can make a lathe using, for example, an engine from a washing machine that has already been killed by time. It is usually asynchronous, you can get 3000 and 400 rpm from it, which is enough for woodworking.

With the help of the machine it will be possible to grind, drill holes, cut and grind wooden blanks. Its main parts to be made: frame; back and front headstock; assistant.

The headstock is one of the most important machine components. It, as well as the power of the motor, depends on the technical characteristics of the unit, the dimensions of the workpieces that will be available for processing.

A frame-body is made using a section of channel No. 14. Segments 30 and 26.5 cm long are cut out of it and welded with the ends, placing the pieces at an angle of 90 ° to one another. A hole is made along the axis of the smaller segment (from the side of the shelves), in which the connector of the bearing assembly should be placed.

The knot is also taken from the washing machine, adjusted to the desired size. Installed on a section of the channel, fixing with bolts. When installing, use a paronite gasket. The oil seal is removed from the assembly, replacing it with a thrust bearing.

A 7 cm pulley and a shaft are made or ordered, on which there should be places for placing bearings. Within a larger section of the channel, between the shelves, a base is made on which the engine is installed with its back to the channel.

Dealing with the tailstock. Two segments of the channel are placed with the walls up parallel to each other. I connect with four transverse metal strips.

In the lower part of the resulting structure, two transverse partitions are welded. Each sleeve is placed with a size of 2 (diameter) x 1.4 (length) cm - one for welding, the second - with nuts.

A shaft is made for the bushings with a center displaced by 2 mm with a diameter of 2 cm and trunnions of 1.4 cm. Due to the displacement of the center, it will lower / rise during rotation. The placement of the shaft in the bushings must provide the clearance necessary for clamping / releasing the headstock.

Take 3 ... 4-centimeter pipe sections with a diameter of 2.1 ... 2.3 cm, weld them coaxially to the M12 bolts (to the heads). Pipes are welded together. The end of the shaft, coming out of their tubes, is provided with a handle.

Collect the tailstock. It is tightened with nuts, ensuring fixation on the support when the handle is turned on the shaft.

Make a quill, which should have a revolving center. Use bearings - one thrust, three straight.

The quill is made from sections of a profile pipe with a section of 3x3 cm, reducing their faces to a size of 2.9x2.9. On the one hand, it is fastened with a rod of 1.2 centimeter length, on the other - with an M12 nut. All straight bearings are pressed onto the rod.

The body of the quill is made using a pipe with a section of 2.9x2.9 cm. One end of it is closed with a metal plate, arranging a central hole in it; in the second, a slot is tripled and a wing nut is welded. Screwing into the last bolt, fix the quill.

I use a stud with an M12 thread on one end, M8 on the other. The flywheel is screwed onto the latter, fastened with the appropriate nut.

The body is supplied with two segments of the corner and attached to the tailstock. The latter is adjusted so that it remains in line with the axis of the headstock.

A handpiece is made with an eccentric clamp. Use a shock absorber. They make two bushings of 2.6 cm diameter, arranging boots on them. Two holes are drilled with diameters of 1.4, 1.0 cm with axes offset from the center by 2 mm. Threaded holes are arranged near the larger end through which the bushings are bolted to the axle.

Prepare a piece of pipe with an inner diameter slightly smaller than the diameter of the rod. A rod with an M12 thread cut at the end is welded to the latter.

The body is made with dimensions of 8x4 cm from the channel. Inside, they are provided with two partitions with holes into which short (1.9 cm) bushings with an inner diameter of 26.5 mm are welded.

The handpiece is fastened by welding it to a piece of pipe, which is cut and supplied at the ends with nuts and bushings. The handpiece is clamped when the bolt is screwed into the latter.

The motor is connected according to the scheme in which it acts as a starting device. Power is connected to the switch input, in one circuit of which there must be a stator. An anchor is connected to the middle outlets. The upper terminals are connected crosswise with the input.

The engine, the headstock are closed with a protective casing. It has a speed controller on it.
