INTRODUCTION Permanent magnet generator also known as Free energy

generator is a machine developed to extract energy from the

surrounding by using principle stated by Tesla.

Tesla stated that the energy is freely available in the nature

therefore it is necessary to develop means of extracting that

particular energy

Permanent magnet generator , as its name implies is concerned

with the induction of EMF in coils by cutting of magnetic flux

by rotating magnetic field.

Power generation using permanent magnet generator(PM

Generator)(Free Energy Generator) is a new system of electric

power generation which is said to be of high efficiency and low

pollution on a household scale

Main Components

1) DC Supply (Excitation)

2) Permanent Magnets

3) Flywheel

4) Copper Coils

5) Rectifier & Filter

6) Controller Switches

7) Initial Rotational Excitation

DC Supply(Excitation)

Permanent magnet generator requires initial excitation to the

coils.

12 volts and above DC supply excitation is required to excite

the electromagnets.

The energy can be freely extracted if we charge the 12v

Battery/DC supply by solar charger The circuit for the same is

shown below:

PERMANENT MAGNET

Neodymium Magnet• The Neodymium Iron Boron, NdFeB, magnets are made of an

alloy primarily consisting of Neodymium, Iron and Boron

• Up to +150 degrees C, the Neodymium Iron Boron magnets are

the strongest performers.

• It is considered as the strongest magnet (RARE EARTH

METAL)

• The "Neo" magnets are a first choice for many applications as

they offer the greatest performance with the smallest volume.

Neodymium Iron Boron, NdFeB, magnets exist in a variety of

grades. These grades not only vary in magnetic output

performance but they also vary with temperature rating

•In our project we require high magnetic field to produce high

voltage of 230v. Hence Neodymium Magnet Is Essential.

Flywheel/Rotor A flywheel is a rotating mechanical device that is used to

store Rotational Energy. Flywheels have a significant moment of

inertia and thus resist changes in rotational speed. The amount of

energy stored in a flywheel is proportional to the square of its

rotational speed

In our project we are going to use circular rotor/flywheel with

permanent magnet inserted on 4 sides.

To mount Rotor/Flywheel ball bearing is used.

The purpose of a ball bearing is to reduce rotational friction and

support Radial and Axial loads.

Copper Coils

Copper Coils are one of the most important component of free

energy generator.

Copper Coils are wound with specific number of turns on any

insulating material

Total Six number of copper coils

are required for free energy

generator ,Divided into two types

1) Driving Coil

2) Generating Coil

Driving Coil Driving coils are two in number. These two coils are mounted

opposite (180 deg)to each other nearer to rotor.

Driving Coil performs the function of Electromagnet producing

magnetic field.

Generating Coil Generating Coils are four in number. These coils are mounted at

90 deg, 180 deg, 270 deg and 360 Deg.

Generating Coils are connected in series which give the required

Ac output

Rectifier & Filter

Free Energy Generator produces 230v AC Voltage.

Application of Generator can be increased by converting AC

voltage into DC voltage . So as to charge a battery, Charging

mobile etc.

Here is a very simple Circuit of a 12V power supply circuit using

LM7812 IC. LM7812 is a three terminal fixed voltage regulator

IC. It has many built in features like thermal shutdown, short

circuit protection, safe operating area protection etc. The output

current of the IC is 1A which is enough to run most electronic

devices.

.

Construction

It consist of flywheel embedded with Neodymium magnets

along circumference having magnetic poles at 0º,90º,180º &

270º.

The flywheel is coupled with a DC Motor.

There are two copper coils called as Driving Coils that are

excited by DC Source. They are mounted separately and held

clear of the disc.

There are four Generating Windings mounted on a disc

allowing them to move through an angle to get optimum

output.

Free Energy Generation

Working

Its working principle is similar to that of a permanent magnet

generator.

A flywheel embedded with neodymium magnets along its

circumference acts as a rotor moving in constant magnetic

field which produced by dc excited copper windings (Drive

Windings).

As initial rotation is given to the flywheel through motor ,it

starts to rotate.

• There are two magnetic fields being developed:

1) Magnetic field due to Drive Windings

2) Magnetic field due to Neodymium magnets embedded on

flywheel.

• These two magnetic fields are produced in such a way that the

resultant magnetic field will act tangentially to the flywheel

giving rotational motion to it.

• The instantly changing magnetic flux will cut the generating

winding and thereby induces emf in generating winding.

Significance(Application)

• Power generation using permanent magnet generator is highly efficient and ecofriendly.

• As it generates an AC output of 60v on a small scale and up to 230 v when implemented on a larger scale, it can be useful to run almost all domestic appliances.

• This generator is useful in remote villages where power is available for a very small duration of time.

• This generator will be useful to Defence Personnel campaigning on borders.

• Hence we conclude that this device will be highly efficient and convenient for domestic appliances.

Advantages

Power generation using permanent magnet generator(PM Generator)(Free Energy Generator) generates power which is said to be of high efficiency and low pollution on a household scale.

Permanent Magnet generator has efficiency greater than 90% without use of any fossil fuel.

It can be made available for specified period of time in remote villages/places to run household appliances for a day or two.
