Mother Nature is great
that gives us so many resources and that’s all free, specifically energy
sources like sun, wind and water. None of them is charged by nature! As the
technology is having advancements, people are looking to harness these free
energy sources to convert and use them for their domestic appliances. This is
the fact that fossil fuel reserves are decreasing and need for alternate energy
sources are getting more. Best way is to harness the solar or wind energy.
The renewable energy
technology is advancing rapidly. Use of wind turbines is best way to harness
the energy. It was used in old times in
form of windmills. Many home owners are
considering to harness wind energy through the help of certain devices.
What is Wind Energy?
Wind energy is a kinetic
energy to convert this energy in form of mechanical energy wind turbine is
needed. Wind turbine is a device with large vaned wheels and it rotates by
wind. Its rotation converts kinetic energy into mechanical energy which then is
converted into electric energy through help of generator. The wind energy can
be used to run simple machines at home. This will reduce your electric bill.
How to build a Wind Turbine for Home?
Its easy to design a
wind turbine for home. You will need this equipment to build a wind turbine:
1-Rods
2-Magnets
3-Bearings
4-Wood planks to
construct a frame
5-Copper wire for
winding
6-Nuts
7-Bolts
8-Inverter
9-Battery
You will need this
equipment to build:
1-Blades
Wood planks will be
used to make the blades, with help of a hammer and chisel you can give the
blades finishing touch as you desire. 25 mm thickness would be the best for
those wood plank made blades. You will have to make a chart for the dimensions
of blades so you can make the blades according to your needs which work
perfectly. Power tools designed for homes can make your task much easier. After finishing the blades you will need to
set them on a rotor, for that you can use double sided tape. Little chiseled
stumps will support the down side of the blade as you plan to fix them on
rotor.
2- Rotors
Initially you will need
two magnet rotors to be designed. You will need coil winding copper wire which
will be placed between the two magnet discs. To make magnetic discs you will
need at least 12 magnets that will be used for each disk. First consider the dimensions
of milling cutter before drilling the holes for magnetic discs. After that place the magnets on the disc with
help of a strong resin. To make rotor discs you have choice to choose between,
medium density fiberboard, iron, stainless steel, or wood.
The magnetic rotor
then will be needed to be drilled as to accommodate 6004 bearing. The support bearings must be placed on either
side of the shaft. The magnet rotor would be designed in such way that it can
hold at least 12 magnets. The magnetic
poles on each rotor should be placed like that they attract the magnets on the
opposite side. It should be made sure
that weight of rotors should be carried by the bolts to have proper balancing.
The hole in the center of the two rotors will secure the stator.
3-Stator
For making stator you
will have to work on number of copper wire which will charge the battery. A 12V
standard battery you will need for that. You will have to make the coils with
help of copper wire, a series of coils in parallel groups. Winding coils will take little time of yours,
but on whole winding coils is the most fun part of this project and you will
enjoy that. While winding coils you must keep 200 turns on each coil.
After
winding position the coils and screw down the stator on the board. Fill the
joints with resin in other to secure the joints and let the components work
smoothly. Now set this your wind energy harnessing design on a testing stick
and see look that your battery and inverter harness the wind energy every time
when turbine swings.
Your wind energy
turbine is ready it is the most reliable source of energy that cost a lot less.
