Build a generator from a washing machine motor using a permanent magnet
Central power supply disruptions, along with exorbitant electricity bills, are increasingly forcing people to think about a self-contained power source. Let the generator be on low power and only work as a backup power source, but it can help when it matters most.
We also decided not to stand back and come up with a “workable version” of turning the asynchronous motor of an old washing machine into a fairly powerful 1.5 kW generator.
If you decide to “quickly tinker” with your own homemade electric generator, “fixing” the engine of the washing machine, it is better to immediately throw the illusions to the side, because “in a quick way” it will not work . First, you will need to solve three main problems:
how to partially remove the core of the old working motor from the washing machine and prepare the grooves for the magnets on it;
where to find neodymium magnets for the generator rotor;
what to do a template for attaching magnets.
Let's solve the first problem. Take an asynchronous motor from the old “washing machine”, disassemble its body, and then, using a lathe, cut off part of the core to a depth of about 2 mm. Set the engine aside for now. Then we will need to buy a set of neodymium magnets, it is easier to order them in the online store. We are waiting for the magnets to come.
After that, we cut the grooves on the machine core of the motor core, 5 mm deep, under the magnets. Here you need to master a trick, it is better to use a familiar turner. Once you have prepared the motor core, you will need to think about what to do to make a mounting pattern for the magnets. We used a strip of tin, although we admit that another material with similar properties could work. Cut a strip lengthwise and lengthwise so that it lies precisely on the surface of the core.
The tin strip also needs to be prepared, namely, mark it along the entire length to place 2 rows of magnets on it so that the magnets are at the same distance. In addition, to turn the electric motor of the washing machine into a generator, we need glue welding, cold, instead of welding we can use epoxy resin and sandpaper.
All that is needed to make a generator from the motor of the washing machine that we have prepared, now we can start the assembly process. We immediately note that only a very patient person can do this work with their own hands. Magnets are constantly peeling off and sticking together, glue flies in all directions and falls not only on the hands, but also on the face. So be extremely careful and follow safety measures when working with potentially dangerous chemicals. We do the following:
We begin to produce a magnetic rotor of the motor in order to transform it into a generator. We glue our tin design for the magnets onto the motor.
A homemade generator needs magnets, so we placed the magnets in two rows on glue.
Carefully fill the space between the magnets with a carefully mashed cold solder. It has the consistency of modeling clay, so no problems should arise.
We grind the generator made from the engine of the washing machine with our own hands with sandpaper. To speed up the process, you can attach the casing to the drill, but you can do it yourself without tools, this will take a little longer.
We have finished making the electric generator from the motor of the washing machine, now we can start the long-awaited tests. In order to check the generator, we need:
rectifier;
Solar charge controller;
multimeter;
motorcycle battery;
generator itself.
You also need to think about how you are going to twist the generator. Fingers are not an option, you can't supply enough revolutions. It is best to use a screwdriver or an electric drill for these purposes. We find on our generator two wires of the working winding and cut off the rest. We connect these wires through the rectifier to the charge controller and in turn connect it to the battery. We put the crocodiles of the multimeter on the battery terminals - that's it and we are ready to test the generator.
We load into the chuck of an electric drill
screw), the generator pulley and dig it out at 800-1000 revolutions. At the output we get 270 volts with moderate sticking of the magnets - not a bad result.
Prospects for using a similar generator
Many people ask, well, we made such a generator, and how, how to apply it in the household so that it brings benefits? Personally, we made this generator with the aim of independently making a gasoline power plant from a morally obsolete, but functional Soviet chainsaw. According to our calculations, the design should have given a penny, which is not the case with gas stations.
As a result, we managed to realize our idea. We connected the chainsaw motor to our generator through the drive belt, securing everything against the frame from the same chainsaw. I didn't even have to bake the frame separately. Our power plant has been working properly since the second year and supplies all energy consumers in a country house. There's enough power to light two rooms and run a computer and a TV.
There are other uses for a fortune generator. In the article wind turbine from the motor of the washing machine Eloquently describes the process of manufacturing the installation, which, using the natural force of the wind, can supply energy to the same country house or garage. Some suggest using this generator to power the ski lift. In general, plug in your imagination and you will also find several ways.
In conclusion, we note that the manufacture of a homemade generator is associated with certain difficulties. The main difficulty is to stick magnets to create a rotor. But you can choose the easiest way - order a ready-made magnetic rotor. In this case, the generator will cost you 200 rubles more, but you will save a lot of time.
