# How Does A Windmill Generate Electricity?

The secret behind wind power is technology that converts mechanical energy to electrical energy.  So, to understand this dynamic, let us first define its components.

Mechanical energy, in physics, describes the sum of potential and kinetic energy that is present in a mechanical system in association with the motion or position of an object.  Generally speaking, this is the energy that is created when you turn a crank that is connected to a shaft and gears which transfer the energy to another set of gears or to another object.

Electrical energy is energy that is transferred through an electric current from a source to an object.  Obviously, you should be quite familiar with how this works.

Electrical generators are necessary for storing the potential electric energy that is generated by the employment of mechanical energy.

Now, when windmills were first developed, they did not generate electricity.  In fact wind (and water) mills operated on the simple principle of transference, which describes how you can transfer energy of one kind to energy of another kind.  Obviously, this still holds true today.  For simple machines, horizontal blades would "collect” or "catch” the wind and begin to turn the crank which is connected to a shaft that could operate another tool.

Today, the mechanical energy that is generated from the turbines, which is the name for the blades that "collect” the wind, is transferred to the generator where the electricity is stored.  You can then connect almost any machine to the generator with wires or cables which will allow you to transfer the energy when you need it.

A windmill generates electricity by the use of motion....when wind pushes the blades a shaft rotates inside an alternator which builds up friction which is then regulated to electrical current and can be used in whatever ways are needed depending on the size of the windmill tells you how much electrical current can be produced

The windmill generates electricity in a very simple way. The basic principle behind electricity generation using a windmill is the conversion of mechanical energy to electrical energy. A windmill has large blades, multiple blades per windmill, that moved as the wind acted on them. Once the wind blew the blades started swivelling. The blades move based on the different air pressures - high and low - created on their surface. The blade of a windmill is basically connected to a shaft. This shaft is connected to a generator. The movement of the blades produces the mechanical energy, which in turn is converted into electrical energy courtesy the electrical generator.

Though there was lot of enthusiasm regarding using a windmill to create electricity earlier on, the interest died out over a period of time as the windmill was found to be not as efficient as required to generate electricity steadily. However, now experiments have shown that it is possible to generate electricity efficiently using a windmill, and it is back in contention as a very viable alternative source of energy.

At what voltage do large windmills (> 1 Mw) generate electricity at? Also at what mechanical speed does the windmill rotate and at what speed does the alternator rotate after gearing? Then, how many pole pairs are there in the rotor to generate at 60 Hz?

The windmill wings are rotated by the wind. The shaft is connected to the generator inside it. The generator has coils of wires which inturn produce electricity through magnetic feild. Thats how it produces electricity. HOPE I HELPED!

Blades of the windmills is connected to shaft, to which it is connected to the commutator.
From commutator it is to be connected to armature. So by rotating the shaft commutator as well as armature will rotates ,so by the conductors a magnetic flux is produced in armature and in field poles.hence voltage is induced.

Actually current is passed through brushes which is fixed .

Windmills convert the kinetic energy from the moving winds to mechanical energy which in turn produces electrical energy through enormous generators called wind turbines. They are more aptly called Wind Power Units (WPU) or Aero generators. They are a clean source of energy as they do not produce CFC gases and do a little harm to the environment compared with other sources of power generation. The typical Horizontal Axis Turbines use a rotor shaft and a generator placed at the top of a tower in order to produce electricity.

A turbine is turned by the wind and that creates static electricity

The wind spins the windmill, which in turn spins a generator, which generates the  electricity. Simple as that.
thanked the writer.
The wind blows into the blades or sails, rotating them. The blades rotating cause a main shaft to spin. The spinning of the main shaft turns the gear motor. Then, the gear motor generates the generator resulting in electricity.

No of poles required will b guided by the speed of armature....for a speed of 1800 rpm you need 4 poles to generate 60 hz. You can have more no of poles for slower speeds of rotation  to generate same frequency...

ITs made of electromagnetic and a metal that is magnect , so when the metal core rotate it cause the magnet field to be cut and produce electrical charge.

Magnet and coil

By spinning a lot witch will send electricity to the power lines witch the power lines is connected to the house and the electricity will work.

Is there a web site for showing a video of how they work.   Or showing them working to show a cub scout den.

How much does a large windmill generate in a year
thanked the writer.
Wind push blades. Blades move shaft. Shaft attached to a generator and makes electricity.

The wind spins the windmill, which in turn spins a generator, which generates electricity from the kinetic energy. Simple as that.

When the wind sticke the fan,the fan rotates .the cuper wire which is b/w the megnet . Produce a field called megneticfield. One wire is conected with wire &other is conected with megnet then electricity is produced.

So so so so la la la la la wind wills are not that hard to know how they work its common sence

Inside of each windmill is a elite team of elfs that work night and day chewing gum which results in the electricity you use to work your computer which pumped full of pornography

Can anyone tell me..
How will I able to get an stablized AC current of 5o to 60 Hz and around 300 v using a wind mill...
