1.1 BACKGROUND OF STUDY
The knowledge you are about to learn is a serious combination of an
engineering trend. And have something to do with the ALTERNATOR.
Here, we make use of a D.C .Motor (direct current motor), and it has
two terminals. This D.C.Motor, have the capacity to generate 12volts and
be use for practical alternating current. Alternating current is a
voltage of like said 220volts - 240volts. All this simple generator generally known as “I better pass my neighbor” can be use for this practical engineering experiment.
What we have here is what we refer as a stator winding (i.e the
generator coil). The stator winding have a three various outputs, it
have the A.C. output, which the red wire gives us the positive, and the
black wire gives us the negative. The capacitor wire, which can be any
color, usually yellow in most generator and the diode wire, also can be
any color but usually green in most generator.
If you don’t connect this winding to our capacitor, we wouldn’t be able
to have our 220V- 240V. the green wire serve as the charging system and is
going to be connected to our 12V battery. The voltage of the
battery(12V) must tally with the capacity of the D.C.Motor (12V, for
tiger generator) you are using. The green wire can be connected to our Diode.
Then from the diode, you supply current directly back to the battery.
The car battery can be 12Volts 45AMPERE, 60 AMPERE, 75AMP or 100 AMP or
120 AMP. Just note that the ampere is the strength of the battery and
the amount of current it can produce and regulate. Make sure that the
battery capacity tallies with that of the D.C.Motor.
We have what we know as ARMATURE, some people call it rotor and a lot of road side electricians call it AMURTURE.
This armature from the supply of the D.C. Motor to the stator winding,
immediately you pass current to the armature, there will be an
interaction between the field (magnetic field) that have been created in
the stator winding and the armature. The armature will be rotating
inside the stator winding, a magnetic field will be created between the
stator winding coil and the coil of the armature, thereby bring out
energy. The energy can come in form of Direct Current, or can come in
form of Alternating current, it all depends on the capacity of the
Now, what we usually use in Nigeria, is a system of Alternating
current, which is from 220V to 240V and if we are able to produce a D.C
with the combination of the alternator, it gives us an alternator and it
gives us a result of 220V to 240V, that means the area of using fuel,
will be off completely, because the battery will serve as our fuel.
We also have a crank shaft cut off. We decided to cut off one side of
the shaft of crank shaft of pestle and rings, so that we can drill a
hole in it, which goes directly to the D.C. motor and it connects the
alternator. So, that gives us the combination of D.C. Motor and
1.2. STATEMENT OF THE PROBLEM
this country, Nigeria, just like most developing countries in the
world, we are faced with the challenges of light disruption. Continuous
spending on fuelling and maintenance of our fuel generator, but now lets
look at another alternative. Converting a fuelled generator into a fuel
less generator and it has a low maintenance cost.
1.3. OBJECTIVE OF THE SEMINAR
aim of this project is to design and manufacture a fuel less generator,
capable of producing 2 – 3 KW of electrical energy/ power. The
a) To design and manufacture of 3KVA fuel less generator.
b) To evaluate the generator for performance.
explore an alternative which is affordable, convenient and efficient,
just like our normal electricity. Here we will learn how to convert a
fuel generator to a fuel less generator.
1.4. SIGNIFICANCE OF STUDY
Why is this study necessary?
study, on how to convert a fuel generator to fuel less generator, Is
becoming more necessary because, as long as the price of fuel is high
and the Power Holdings Company of Nigeria (P.H.C.N) keep disappointing,
it is recommended that one should fall back on this technology of
Personal Electricity Generator (P.E.G).
can use this fuel less generator to be charging car batteries and as
well as using it to generate electricity for his shops, flats or rooms,
thereby making money in the process.
need to use in the school environment, like office, labs or even in the
classrooms, as case maybe. Also, in tertiary institutions is also
This fuel less generator can be used to power and
sustain a constant or stable electricity /current in a clinic,
hospitals or even a maternity. Knowing full well that it can power and
supply a stady current for more than 24 hours without a stop.
/ stalls owners can have this fuel less generator to attract more
customers, by having steady power to make the customer feel comfortable.
Who will benefit?
fuel less generator is beneficial to everyone both for the young or for
the old. A family, travelling to the village or to a camp or even a
vacation, can decide to carry one of this fuel less generator along to
avoid disappointment by PHCN, or better still, get one of this fuel less
generator for their parents or grand parents. This generator is easy to operate and cheap to maintain.
average Nigerian doing one business or the other can get one this
generator, even if it the small tiger one and he or she can be sure of
constant and stable light throughout the day and night.
owners will have no cause to frawn their faces on the high cost of
petrol and the constant disappointment from PHCN, because with a medium
or big fuel less generator, he/she will have a noiseless and smokeless
generator and constant supply of electricity to boost his business.
the posed danger of a fuel generator as smoke (as air pollution) can
cause lung disease, then Noise, which irritate both the owner and their
neighbors and finally the High Price of fuel can all be avoided if one
get one of these fuel less generator.
