In order not to be left without electricity during network outages, as well as to use electrical appliances where there is no electrification at all, you need an electric generator. This does not have to be a purchased device; for unpretentious consumers, a homemade generator is sufficient. You can make it based on the engine from a washing machine.
Materials:
- Motor from a washing machine;
- acrylic or epoxy resin;
- neodymium magnets 30x5 mm – 16 pcs. -
- brush cutter.
Electric generator manufacturing process
To manufacture the generator, it is necessary to remove the rotor from the working electric motor from the washing machine.
The anchor needs to be ground down, reducing its diameter. This can be done by clamping its shaft in a drilling machine and grinding the core with a grinder with a flap wheel. This is even easier to do on a lathe.
On the machined anchor you need to install 8 rows of 2 neodymium magnets. The polarity of adjacent pairs must alternate.
Now you need to fix the magnets with resin. To do this, formwork is assembled at the anchor from a CD and a piece of plastic pipe. It can be glued with hot glue.Then resin is poured into it.
After the resin has hardened, the formwork is cut off. Then you grind the anchor to balance it. As a result, it should fit into the motor stator without any problems.
The engine is reassembled with the rotor already modified. Now you need to determine its working winding with a multimeter, since 220V can be removed from it when spinning up the generator. In this case it is the yellow and red wire. The blue core of the starting winding is cut off.
Mountings are welded to the generator. It is then screwed to the board. You need to attach a gasoline engine to the side; you can install a motor from a brush cutter. They are then connected by a drive belt. A socket connected to the generator wires is also attached to the board.
Now, when starting a gasoline engine, it will spin up the generator, which allows you to receive 220V. The frequency of the current is not as stable as in a regular network, so it is better not to connect sensitive electrical appliances to it without a voltage regulator. However, such a generator is capable of powering a pump, fan, etc.
