it is not a led bulb...... it is a 75 W 230 V bulb......

we are not losing time.....

time is precious....

2 coils 40 ohms each....

neodymyum sphere 30 mm 

Dc motor 4 V 

 

it is simple....

all is matter is the positionmetal case pot - sphere - between the poles.

 

thx st

You mean you have a 4V motor spinning a neodymium sphere and producing 75W at 230V? Is that right? 

 

If so you have a 19Amp current through the 4V motor. (W=Vi, remember.) This will burn most 4V motors out instantly. 

 

Something is wrong here. 

 

Can you provide details of the energy balance? 

 

Or are you just another perpetual motion crank?

we are testing in that movie to se if it is working..... you can test it but please be careful, and take all the safety measures because a spining neodymyum sphere at high rpms can be dangerous if you will not make a proper  metal case pot for it........

I provide only the construction details, it is not perpetual motion it is just another aproach regarding the clasic dynamo, in theory know it is posible to have a bycycle with a modyfied dynamo which is lighting a car bulb 55 W

I.m interested to find an aplication more important regarding the magnetic flux generated by a spininig magnetic sphere than a mini generator created in educational purpose not industrial.....

thx st

No, I asked you to provide an energy balance for this. Where is the 75W coming from? From just the spinning of a 4V motor? If so the power of the motor has to be at least 75W (i.e. assuming no loss in the generation process which is most unlikely). And that means you must have an unbelievable current of 19A through this little motor.

If you cannot provide a plausible explanation of what you are doing I will conclude this a scam.

[sciencetoolbar]

if you will conclude it is a scam it means you have to ask your teachers or someone who is more than prepared in this field if it a scam or not.
do not hurry .....the bulb is 75W this means maybe it is not lighting at the maximum power. usual I don.t unswer to those who are saying it is a scam you are an exception.

I will give the details of the bateryes 2 peaces 3.7 V 1800 mAh each now you can calculate the input power....

Well you should be able to do this. But OK, 1800mAh = 1.8Ah which means if the current were 18amps the battery would go flat in 6 minutes.

Can you tell me the power rating of the motor? If you bought it you should see that on the box somewhere. My bet is it will be less than 10W.

But in any case what is the point of this supposed demonstration, which I have difficulty believing? What do you think it shows? For what purpose did you make the video?

[sciencetoolbar]

I have 2 batteryes in series....
not one....the motor is from this....http://www.heinner.c...ewdriver-csd19n
I have done this because I.m studing the magnetic flux for other purposes.....and I saw on internet movies with people making scams to light a bulb with a battery so I decide to do an educational movie maybe will help the scam guys to learn something.....are you agree?

[sciencetoolbar]

you can use any kind of motor you wish to rotate the sphere, gas, pressured,air, CH3OH engine.....I have used electeric and a battery or 2....so do you still think it is a scam ? that why I have disabled the comments because I wish to help the scam guys to transform in reality the scams and maybe someone will find an important aplication of the magnetic flux.......simple

That screwdriver motor uses a 3.7 V 600mAh battery. So, if used for 1 hour it will use continuous power of just over 2 Watts. You say you are powering it with two 3.7 V batteries rated at 1.8Ah each, connected in series. I hope you mean in parallel, as a series connection gains you nothing in terms of Ah and the series voltage is double what the motor is rated for!

I am going to assume a parallel arrangement, so you have a 3.7 V battery rated at 3.6 Ah. If the motor draws 3.6 Amps, the power consumption of the motor is now up to 13.3 Watts, more than the motor is rated for, and you still aren’t lighting a 75 Watt bulb with that!

I am not going to bother watching the videos since either you do not have a clue what you are talking about or you are intentionally giving out false information here. I don’t know why you would do that and I am not interested in finding out.

He might well be lighting a light bulb.  Remember, even 5W will make a 75W bulb glow a little.

But such a statement is deceptive. That is like saying you can fill a 55 gallon drum by pouring one 5 gallon bucket into it.

If all he has is 13 watts of input power, the honest thing to do is say the device can light a 12 Watt bulb.

Right; he's not being honest at all.  But to give him the benefit of the doubt, he may simply have no clue how much power he's getting out.

I would agree.  He sounds like he knows nothing of substance of basic electrical theory.  My degree is in electrical engineering; it sounds like baby babble.

Well OK,in the light of the comments by billvon it may be that it is not a scam and that you are getting just a feeble glow from the bulb, i.e. nothing like 75W. This could be consistent with the power input from your little motor.

The basic issue is that you will only generate an output of, at most, the power that you put into it, and in practice rather less, due to inefficiency in the generation. If your motor is a 5W motor, 5W is the most you will be getting from the bulb.

Should that not be "in the faint glow of the comments . . . ."

So guys, It doesn't matter for me how much advanced you are with the knowledges or not, but if you have doubts ask a specialist for example a physycs professor,  if it is posible or not before making wrong  assumptions how much do I do know in the field or not......I said I.m studying the magnetic flux generated by a magnetic spinning sphere peace of cake...,....this means...... you are making wrong assumptions. Time is precious for me and for you.To  the ones who are thinking they are the smartest people on the earth because they have a diploma... and the more prepared ones I kindly sugest them to stay out of this and let just the interested ones to discuss. From my point of view I can discuss with a 7 year boy or girl because it is a simple thing! 

So if you are profesionits you will replicate it at a small scale measure it and then have your conclusions I already have mines but minse are private from a simple reason this is not a show. television .......

Well great. Maybe if you explained just how you are "studying the magnetic flux generated by a magnetic spinning sphere" there may be grounds for an interesting discussion. What is your methodology used to study the flux? Why do you feel the spinning sphere is better (more efficient) than a standard armature dynamo? These are the sort of questions that interest scientists, not whether or not you can get a bit of a glow out of an oversized light bulb by overdriving a small motor.
