How do Wind Turbines work?
For those asking how
do wind turbines work, what is there purpose and why they should be considered. Keep reading. Wind energy is
not only renewable or environmentally sound. Its primary benefit is to capture the wind currents passing
through & converting it. This is generally known as kinetic energy.
Many people in regional Australia are looking at various ways to generate electricity from
sources other than the generator. The wind is one of the most evident sources of natural energy.
A wind energy system may seem to be built with very complicated and expensive machinery, but in
fact it’s not like that. It’s possible to build your own wind turbine having paid no more than $500au
for the parts required and the added expense of your time.

How it all
The major parts of a wind turbine include a DC motor, body and tail assemblies, blades, a tower
and a battery bank to store all of that free wind energy. Of course, you can mount the turbine on the top of
your roof, but a wind turbine mounted on a tower will generally perform much better.
The basic principle of how the wind turbine works is simple: it captures the kinetic energy of
wind with the blades and converts it to the electricity with the DC motor. The DC motor itself has a shaft
that is actually spinning and moving the magnets inside it. The movement of magnets creates DC electricity
which can be stored in batteries.
It’s best if the wind turbine is located approximately 5 metres above any obstruction for a radius of 300 metres and the
turbine has the shaft parallel to the ground. This model requires a relatively small foundation and is able to
self-align with the wind.
Thinking about employing a wind turbine, you need to ask yourself about:
How much electricity do you need?
What are the construction and installation costs for your configuration?
What is the total cost of ownership (TCO) of the wind turbine?
Most households use approximately 20 -30 kilowatt hours per day, but you can obtain more
accurate information from your electricity bill. To calculate how much electricity can be produced by a
wind turbine, you need to know the wind speed over time in your location and the amount of electricity a
turbine generates at the different wind speeds. Wind speeds are often measured in kilometres per hour (kph).
Generally, wind speeds greater that 11 kph are needed before a wind turbine can start to generate
To find out the wind speeds in your area is simple through The Australian Weather Bureau
http://www.bom.gov.au . The spinning speed of DC motor’s shaft approximately equals the wind speed multiplied by 3.
The DC motor’s specification should give you the key to the amount of electricity produced from this
Generally, you will need both AC and DC for your home. DC
power is produced by the wind turbine and can be stored in batteries. Then it can be converted to AC by using an
inverter. How do wind turbines work and all other related information is described in detail in Les & Jane
