When the washing machine breaks down and it is no longer practical to repair it, it becomes necessary to purchase a new one. Do not rush to throw away the old washing machine. If a engine in working order, then why good disappear. From it you can make many useful things that will be useful to you around the house. Let's look at what can be done from the engine from an old washing machine.
Electric emery from the engine of a washing machine
One of the applications for the engine from washing machines is the manufacture of electric emery. This device will be very useful in the household. Thanks to him, you can quickly sharpen a knife, drill, scissors and any other cutting tool. Of course, the task is not one of the easiest, but with a skillful approach, everything can be done quickly enough.
The first and most important task is to attach a grindstone to the engine itself, or rather, to the engine shaft. The problem is that the main diameter of the hole in the grindstone and the diameter of the washing machine motor shaft are completely different. This problem is being solved. It is necessary to prepare a special flange, which will have two different sides.On the one hand, there will be the necessary thread to securely fasten the emery wheel, and on the other hand, the motor shaft will be pressed in. To make the flange, you will need a small piece of steel pipe with a diameter of 32 millimeters.
Flange manufacturing process:
- We take the necessary pipe (by 32 millimeters). The length of the pipe should not exceed 20 centimeters.
- Now you need to cut the thread on one end of the pipe. For reliable fixation of the flange on the shaft, it is necessary that the thickness of the emery wheel be half the length of the thread. It is very important to consider the direction of the thread. It should be cut in the opposite direction of rotation of the motor shaft. Otherwise, the whetstone will simply fly off the shaft during rotation.
- The other end of the shaft must be heated with a blowtorch and pressed onto the shaft. After cooling, the pipe will securely fasten to the shaft. For a stronger connection, you can weld the pipe to the shaft. If there is no welding, then you can simply drill a hole and connect with a bolt and nut.
- Now you need to pick up three nuts and two washers of the required size. At the end of the threaded pipe, we screw one nut all the way, put on the appropriate washer, then an emery wheel, then another washer and tighten it all with the second nut. You need to tighten everything tightly, and at the end also secure it with a third nut.
The main task is completed, now you need to secure the engine in a secure way. The mounting stand is made depending on the availability of mounting holes on the engine. After making the stand, we fix the engine on the workbench. Motor brackets on some washing machines are great for mounting on a workbench.
Electrical connection
After the engine with emery is fixed on the workbench, you need to connect it to the power supply.
- Using a special multimeter, you need to find a working output. To do this, you need to check the resistance of each output. The resistance at the working output should be about 12 ohms.
- We make the connection of the working output to the mains.
- To start the work of emery, you need a special starting device. If it is not there, then the start of the emery can be done by hand, strongly twisting the emery stone in the direction of rotation.
This completes the manufacturing process of electric emery. The device is ready to work.
Making a lawn mower from a washing machine engine
Making a lawn mower is another option for the competent use of the engine from a washing machine. This device is very useful for those who have summer cottages and personal plots. For the manufacture of a lawn mower, a lot of materials are not required, all components can be obtained in a barn and garage.
Manufacturing process
- First of all, you need to get a chassis with which it will move. For this, wheels from any trolley or baby carriage are suitable.
- A specially prepared metal platform must be installed on the chassis. You can make a platform either from a metal sheet and a square profile corner. A special frame is made from the corner. Wheel racks are already welded to it.
- For the handle, you can adapt a pipe of not too large diameter. The height of the handle is selected according to the height of the person who will operate it. The handle is welded to the frame using gas or electric arc welding.
- Now you need to prepare a hole in the platform so that the motor shaft can freely pass into it.
- Next, in the front, you need to place the grille. The grille is screwed on with bolts. The grill must have special gaps. 2 cm at the top and 1 cm at the bottom.
- The engine is mounted on the platform in such a way that the shaft passes into a specially prepared hole. By welding or by pressing on the end of the shaft, you need to fix the cutting tool (knives).
- To protect the engine from grass getting into it, you need to close it with a protective cover. However, it should be borne in mind that the engine can heat up and needs cooling. Therefore, there should be small holes in the protective casing.
- Now we connect the power cable. As in the case of making emery, you need to find a working output with a multimeter. A cable is attached to it. A cut with a plug and a special switch must be brought to the handle of the lawn mower.
This lawn mower manufacturing process is completed. To prevent accidental electric shock, it is best to rubberize the handles. Now the device is ready for use.
Making a feed cutter from a washing machine engine
From the engine of the washing machine, you can also construct a feed cutter. This device will perfectly cut various fruits and vegetables of large sizes into small pieces. A very useful household item.
Feed cutting technology
- To make a feed cutter, you will also need a drum from a washing machine. In its rear part, you will need to make a hole along the diameter of the motor shaft.
- Four holes must be made along the edges of the drum. Bolts will be attached in these places. A large hole is made in one wall. It is through it that the finished raw material will fall out.
- The cutting element must be installed on the end of the motor shaft with a few bolts.The cutting element must consist of two knives. The lower knife should be with slightly curved ends.
- The entire resulting structure should be mounted on a support, which is made in the form of a stool with four legs.
- The top of the drum must be closed with a lid, otherwise the materials will fly out of the drum during grinding.
- As for the power supply, everything is here, as with previous alterations. We find the working output and connect the power cable to it.
The feed cutter is ready to go. Thanks to such a device, in just one hour, up to 100 kilograms of raw materials can be processed in various cities.
Making a concrete mixer from a washing machine engine
If you are planning a construction project, then do not rush to throw away your old washing machine. From it you can make a full-fledged concrete mixer, which will greatly facilitate your construction process.
The process of performing work on the manufacture of concrete mixers
- First you need to make a stable base on which the device will be located. You can make it from a wooden bar 150 by 150. The bars are fastened using self-tapping screws. The base can also be made of metal channels or corners. The base made of metal is more stable and reliable.
- The motor shaft and the shaft of the container itself must be in the same plane. With this calculation, it is necessary to make special shelves for mounting the engine on the frame.
- Next, install the gearbox. The gear and motor pulley must be in the same plane. If this condition is not met, then the engine will experience large overloads and will soon stop working.
- As a container for kneading, you can use the tank of the same washing machine. A shaft is installed in the container and special blades for kneading are attached to it.It is very important to observe the symmetry of the arrangement of the blades. They should be clearly opposite each other.
- Now we connect the wiring, make the start and shutdown buttons. We pull the belts on the pulleys.
- To protect the gearbox and the engine from the ingress of concrete, it would be better to close them with protective covers.
Making a generator from a washing machine engine
From the engine of a washing machine, you can make a 12 V generator. To make it does not require a lot of work and a lot of additional materials. All that is needed is 32 specially sized magnets (20 x 10 x 5 millimeters).
The whole process of alteration is that you need to remove the core layer and install special magnets. The rotor has four poles, each pole has eight magnets. On a lathe, you need to remove a small layer of the core and install magnets in these recesses. Then the poles must be filled with epoxy resin, after wrapping them with paper. Now you need to install new bearings. Find the working winding, and cut off the old wires. The generator is ready to work.
If you have imagination, working hands and the necessary knowledge, then on the basis of the above examples, you can assemble other devices and devices for various purposes. All the fundamental principles are set out in the examples above. The analogy of production in most cases will be the same, with the exception of characteristic nuances.
