Power Generation from Alternator Using Induction Motor

No....

Converting one form of energy to another form of energy, creates a loss of energy, because no transition is 100% efficient....So if you start with electricity which was produced from heat and then convert it to mechanical energy via electrical motor, there is a loss of energy. then if you convert the mechanical energy to electrical energy again, via generator, there is an additional loss of energy.......You cannot increase the amount of energy you have without adding energy in whatever form you choose that works....flywheels are for storing energy, they use energy they don't create it....If you want to supply electrical power, you need a source of energy to convert to electricity, like the sun, or wind, or a gas powered generator, or a hydroelectric generator driven by flowing water....you can't multiply energy with a device, you can only convert one form of energy to another....

Yes, just plug the output of the alternator back into the 30HP motor..

Now seriously.. What's the point of this exercise?

The main point behind all this exercise is to generate low cost electricity and provide this electricity to poor and rural areas.

what will be the power source? A generator to get the motor running and the flywheel spinning the first time? And then it runs on it's own?

If so, there is a problem with your calculation

No, limited electricity power is there but, what if we can generate high electricity from a low power connection.

This is what i am thinking & planning;

Machines that intend for more power to come out than goes in are sometimes called "over unity" devices. The problem with the concept is that this universe does not work in that way. Such concepts are given short shrift by CR4 readers because the vast majority of them understand that such machines cannot work, for were they to do so then this universe would explode and cease to exist.

A curiosity: if it were possible, then why is it not being done already [rhetorical question - NNTR]?

Without getting too elaborate on the theory behind your idea, you are trying to make a machine that will perform useful work without the use of any power source other than the initial push of getting the flywheel moving. Such devices are known as "over-unity" or "perpetual motion" machines. You can Google on both of those phrases for much more information.

In case you are not understanding, here is the simple math.

You want to achieve 300kVA output to use in your rural area. You want to get this from a 30HP motor, which if we assume is .8 power factor, will be essentially 37.5kVA. So you are thinking that you will input 37.5kVA and get 300kVA out of it. This violates the first law of thermodynamics, that says essentially that you cannot get anything out of something that did not go into it in the first place. So in your proposed system, where is the other 262.5kVA going to come from?

Answer; FM...

Freaking Magic...

Real answer; the power you can get from a 30HP motor cannot exceed 30HP, in fact it cannot even approach 30HP, because there are losses in the motor and alternator and transmission system and distribution system etc. You can porobably get no more than about 30kVA out of it.

Ignoring the fact your proposed motor is too small to power your proposed alternator the application really boils down to one of complexity and economics.

What you are wanting to do here is actually more complicated (and very dangerous) than you may realise and shouldn't be undertaken by someone without proper training and construction facilities. However the biggest problem is cost, as you are better of buying a proper generator than trying to build one.

Consider research into a smaller Hydro water wheel powered generator instead as a better starting point, it doesn't need expensive fuel which a 300kVA will consume at a startling rate. Small hand crank generators are also very popular, and again there are plenty on the market already, some specifically designed for poor countries where cost and reliability are very important.

Seems as though every time someone thinks of this, they somehow believe that the entire world has missed it for over a century, and they are the dawn of the new age!

Dear Abduul86,

My basic question to you is "why do you want generate electrical power by using induction motor - which needs electrical power.?

Further, the Induction motor will have a slip of 4% and hence th frequency of the alternator also will be less.

You have not mentioned the dia of the fly wheel, which has an impact in the Gd^2 value, and hence starting and full speed reaching will take more time, and hence starting current will be larger and take more time to reach below full-load current.

The different combinations Sl. No.3 , 4, and 5 referred by you will result in power loss in transmission as per the Engineering Standards.

DHAYANANDHAN.S

This is beginning to look like an over unity energy generation question.

See previous threads on CR4 where this has been asked and we have answered this (sometimes in great detail), including one where someone had the great idea to use increasingly larger motors hooked to alternators powering bigger motors and alternators so a small battery could produce orders of magnitude more power.

Thanks @RAMConsult & @PWSlack, for the suggesting me the valuable readings. I found the same concept over internet, yes this is a concept related with over unity energy generation.

Over unity energy generation doesn't work and never will. If you really want to help the poor, concentrate on the REAL energy generation methods we have mentioned above.
