Wind Generator

Introduction to wind generator:

Wind generator: It is a device used for generating electricity by using power of wind. Let us go into the details of generator and how electricity is generated.

Electric generator: The device used for converting mechanical energy into electrical energy is called electric generator. The mechanical energy can be in the form of wind power , hydro power , coal power , nuclear power etc.Please express your views of this topic Electric and Magnetic Fields by commenting on blog.


Components of electric generator:


Components of electric generator:-

(1)   Magnetic field

(2)   Armature Coil

(3)   Mover

(4)   Rotor

(5)   Slip Rings

(6)   Stators

I have recently faced lot of problem while learning Momentum Equation, But thank to online resources of science which helped me to learn myself easily on net.

Wind generator :


Magnetic Field – It is supplied by coils placed in the generator which get feed of current from a source.

Armature coil – It consists of a large number of coils wounded together. It is the current carrying member of the generator and here voltage is produced.

Mover – It is the external source which moves the generator such as wind power, hydropower, coal power etc .

Rotor – The component, which rotates with in the generator, is called rotor.

It gets the driving power from the mover of the generator.

Slip Rings – These are the circular conducting parts of a generator and are used to transfer electric power to external agency.

Stators- The stationary parts of a generator are called stators.

A wind generator has a wind turbine attached to it. It acts as a propeller for the generator and it rotates the rotor. The rotating rotor changes electric flux linked with the armature coil. The change in flux linked with the armature coil produces electric voltage and thus electric current is  produced.

Some of Advantages of wing generator is that it produces clean energy , without any pollution and polluting wastes. More over is utilizes naturally produced wind power , which if untapped results in wastage of natural power.

Some of the disadvantages is that it need a lot of space for setting up windmills.

It can be concluded that new technological advancements are required for setting up wind generators in small area
