Where You Can Adapt The Engine From A Washing Machine

A deteriorated washing machine should not be thrown away immediately. Especially if there are sufficiently developed skills for working with hand tools, and there is a habit of messing around in the workshop. Various homemade products from the engine from the washing machine can be extremely useful in the household.

What are the engines

The class and age of the machine determines which engine is in the hands. If we are talking about the old, Soviet. it will be asynchronous device open type, quite reliable. The engine from an old drum-type washing machine has a power of 180 watts, but it is very convenient for home-made products, since it has excellent torque indicators. In other cases, it may fall into the hands of:

  • two-speed engine from the washer with a fixed 350 and 2800 rpm;
  • a collector unit, which, with direct voltage supply without adjustment, accelerates the shaft to 12-15,000 rpm;
  • engines from modern washing machines of various classes, since today manufacturers often do not follow the general standard of equipment.

Where You Can Adapt The Engine From A Washing Machine

Worth mentioning right away inverter motor which is equipped with the most modern washing machine. To run such an aggregate, a control circuit is needed. It must first convert the alternating current to direct, and then create a new signal and change the frequency of the output voltage to control the speed on the shaft. But if there is power electronics from the washing machine in the engine kit, this will be an extremely useful addition.

Motor connection

To lay the wires of the winding need a multimeter. It will also be useful to prepare side cutters or pliers for stripping the veins. The list of other tools depends on which equipment will be assembled to the engine.

Connection of the unit to alternating current.

  1. We define pairs. We apply one probe to any core, and we check the others with the other. If the multimeter gave a signal, it means that the pair was found.
  2. We find the resistance indicator of the two windings. The highest value indicates the starting pair.
  3. Different tandems are connected in pairs, and then connected to a common 220 V.
  4. The shutdown button can be installed on the cable of the starting winding.

Sometimes it is necessary to reverse the direction of rotation of the engine. Simply change the outputs of the starting winding.

Grinding machine or sharpener from the washing machine engine

After the electrical connection is completed and the washing machine motor comes to life, you can start making homemade products. The most common is a small sharpener. If you use a circle from an angle grinder, you can cut plastic pipes, an aluminum corner.

You can adapt the engine to work as a grinder, for this is placed on the shaft small or coarse circular nozzle. The list of works is as follows:

  1. The engine must be securely fastened. This is most conveniently done on a small board, which is then easily placed on a table, workbench, any convenient surface.
  2. You can mount the motor of the old washing machine on the corners or galvanized steel circular clamps. To compensate for vibration and electrical insulation, in the latter case, rubber is placed between the engine and the fasteners.
  3. Asynchronous motors from old drum washers have an open design, which gets dust, moisture, sawdust. This can cause faults and failures of various types. Therefore, when mounting, the most profitable option is completely “hug” the engine with a strip of galvanized steel.

There are several ways to connect a chuck or a seat for grinding a wheel, a wheel for an angle grinder, and nozzles for grinding.

  1. Cut the thread of the chuck fitting directly onto the shaft.
  2. Weld an adapter from several pipes of different diameters. On one side, the grinding wheel is expected to fit, and on the other, the inner diameter of the tube must match the shaft dimension. This part of the adapter is heated, stuffed onto the shaft, after cooling, the parts are very tightly and reliably connected.

It is worth noting that a chuck for a drill is the most attractive option, unless you want to make a sharpener with a stone. It is easy to place almost any tool in it: a drill, a mill, a grinding round head, a nozzle with a wire brush for peeling paint, and a felt block. There is no difficulty in manufacturing an adapter for a circle angle grinder.

Such a machine tool can even be assembled by a novice home master and used for a variety of purposes. The main thing is to properly connect the engine and spend some effort on the formation of a reliable fastening of the working unit.

Advice! If only a high-speed engine is available, it is recommended not to reduce its speed, but to make a separate unit with its own shaft, and transmit torque to it through a pulley with a decreasing coefficient.

Other homemade sharpener-based designs

The above work will have to be done if you want to get other, the most diverse machines.

  1. Wood turning. An engine of 180 watts from the old washing machine will allow, with little effort, slowly, to process cylindrical workpieces. Necessarily need a kind of tailstock to stop the workpiece. This will protect the motor shaft from side loads.
  2. Drum grinding. For this, a large-diameter wooden cylinder is used, in the center of which a steel rod passes, one end of which is clamped into the engine chuck, the other is mounted in a stand on a bearing. The surface is glued with sandpaper, you can sharpen knives, planer blades, if there are devices for maintaining the angle, and perform other operations.

Just note, the sawmill from the washing machine engine will not work. there will not be enough torque.

But furniture makers and other home craftsmen will like the idea of ​​manufacturing horizontal drilling fixtures for working with eccentric fasteners.

  1. A machine is made, as described above, with a chuck on the shaft.
  2. A support, guide shelf, horizontal, is made at such a height that the axis of the shaft passes through the center of the end face of the chipboard plate or wood part.
  3. A drill is inserted into the chuck, the part is fed horizontally, and the drilling depth can be monitored visually.

To create a mounting location for a circular eccentric, it is enough to use a drill, a vertical drilling machine and a mill of the desired diameter. This operation does not require high precision. The main, responsible task of accurately drilling a channel for a cylindrical pin will be done by the engine from the old washing machine.

Grain crusher

Equipment of such a plan can significantly save on the production of feed for livestock. If a sufficiently powerful engine is available, then a completely sensible grain crusher can be built, which is in no way inferior in return to industrial options. Motors on large washing machines of an average budget or premium level have similar characteristics.
In addition to the unit need a case. The best option would be a design from an old top-loading machine. If such a case was not at hand, then you can find a lot of options at almost any point for receiving metal for a penny.

  1. When choosing knives, it should be noted that at the time of cutting they should almost touch the edges of the body, not reaching 3-4 mm.
  2. On the bottom of the structure, you need to make a hole to divert the finished feed.
  3. We install two blades inside: one is 40-50 cm away from the upper edge, and the second is at the bottom. It is better to use two shafts rotating in different directions for better grinding.
  4. We fix the engine on the upper part of the washing machine and assemble the shafts with it.
  5. Loading the grain crusher will become more convenient if you make a hole in the lid, rather than removing it every time.

Important! During grinding, the engine will need periodic rest.

Concrete mixer

Renting and even more so buying factory equipment is fraught with serious expenses. For work of medium complexity it will be more practical to make a concrete mixer with your own hands. If you use the engine from a powerful washing machine, the efficiency of the equipment will increase markedly.
Assembly of concrete mixer.

  1. The foundation must be stable. The welded channel is ideal, but you can save and replace them with a wooden beam. We choose the height at our discretion, but not lower than 0.5 m.
  2. The motor shafts and tanks must be in the same plane. For this purpose, special shelves fixing the motor are provided in the design.
  3. We install the gearbox so that the pulley and motor are on the same level. Otherwise, the unit will very quickly fail due to severe overloads.
  4. An old centrifuge of a washing machine can act as a container. We mount the shaft in the tank and symmetrically fix the curved blades on it, which will interfere with the solution.
  5. Putting the Start and Shutdown buttons together with the rest of the wiring.
  6. We put the belts on the pulleys and, if necessary, tighten them.

When fully loaded, part of the solution may splash out onto the gearbox and motor. Therefore, it will be useful to organize protection for them: hard or soft casings from improvised materials.

Vibrating table

Another useful equipment widely used for the production of paving slabs. In contrast to the solutions described above, this design is noticeably simpler. For assembly, you will need a table and a separate metal plate.
Assembly of the vibrating table.

  1. At each corner of the plate we weld along a spring of the same height.
  2. At the corners of the table, we similarly organize a receiver for them of comparable size.
  3. Between the legs we fix the engine by means of transverse metal strips.
  4. We stretch the wiring and display the unit on / off.

Advice! If the table is large or the engine is not so powerful, then the vibration force can be increased by installing the motor on eccentrics that will swing it.

Conclusion

In the matter of homemade items from the old washer, everything is decided by the imagination and specific engineering skills of the performer. It is easy to make a fruit cutter, a lawn mower with steel knives, an electric scythe with a string cutting unit, even an installation for plucking feathers from chicken and duck carcasses. The main thing is to carefully approach the solution of the task.
Not only a washing machine can become the basis for various homemade products. You can give a second life to a microwave, a refrigerator, and a vacuum cleaner. If you do not know how or simply do not want to use outdated equipment, you can get rid of it in various ways, described in this article.
