Hi folks, hi blackchisel97, not sure if you've noticed this as I have with J.B. solid state circuit. I'm charge/conditioning a 6 cell nicad 1700mah pack and drawing 400 milliamps input using 13.8vdc supply and when I try the 1 ohm test the input drops to 140 milliamps and volts across 1 ohm show .6 volts and i notice the frequency decrease when making the 1 ohm test and when charging the battery the frequency is at least double if not triple. Does anyone know if when put back on charge battery, is it still seeing the same overall output watts with maybe a reduced voltage due to lower impedance, so as to be in the safe region as per the 1 ohm test. This confuses me since I thought with the blocking flyback diode it was supposed to be independent from input, transistor off collapsing field. It's charging well though and bringing the battery back to life. Any thoughts appreciated.
peace love light

Hi
i really like this idea for this but i was think if we have ups we know the battery for the ups will down maybe after 15 min what will happen if we use it maybe will work or maybe now if its work really we will have FREE ENERGY source for long long time .

correct me if iam wrong just think

Out of curiosity... does anyone know how the speed and input power compare to how the motor's ran originally?

Interesting thread. Anyone try this using hard drive motors. I notice they have 4 leads that seem to be going to a pulsed logic circuit, like a stepper motor is what i was thinking. I could be wrong with that assumption. Ive tried powering them up by themselves without any luck. Seems they need a stepped input pulse to each terminal

Hi Imhotep / All,

First of all thanks to Imhotep for sharing the fan circuit and immense help to make this so called Bendini's generator.

I have recently made this and I could see the following.

1. I could get high voltage out of this circuit (in the form of back-emf) w/ no load i.e no charge battery and my multimeter reading reaches ~ 120v where input battery was 5v DC. So I believe it is working as expectation. Neon bulb is lit w/ no load as well.

2. Now I put the load in the circuit, in the form of charge battery (as specified after diode) and I could see the neon bulb is getting off, voltage (120v drops to lot less ~ 12 - 17v) and the current from o/p is ONLY ~ 1mA to 5 mA. Which is very very less current I believe. Now the question is, whether this is expected?

3. I started doing some modification related to operating frequency of the circuit and found a bit good result in current drawn to load and the load current max I could get from this circuit is ~50 mA. Which still I believe very less to charge a battery, I mean charge battery will take long hours to get charged. :-(

I couldn't see any post (lot of people had worked on this though) that what is expected current o/p from this circuit? And even if this is a circuit of generation of high voltage w/o load and w/ load the current drawn is very less I don’t know what would be practical use of this. One more point, if I just connect the charge battery (load) to the input battery directly then the current drawn is much more (~ 100mA), so I think the source battery is supplying all the needs and as per physics principle there is no free energy at all.

I really don't know whether this is correct forum to place these questions or not, even I also don't know whether this thread is still active or not, as Imhotep's original post was really quite a while ago... but still I am putting my doubts over here and request Imhotep if you can kindly help me out.

Thanks a lot in advance. Thanks once more for creation of videos for making the fan circuit very easily...it was a great help I would say...

Hope you would reply with your valued comments.

Thanks,

Yes. That is expected behaviour. Output will have outptu voltage inverse with load resistance. Load with high resistance will be charged at higher voltage. Think this circuit as charger with constant power output.


You can increase output, but not with this version. You need to use bigger coil to get bigger output.

However, you should notice a significant charging speed compared to normal charger. My variant charge about 4 times faster than common charger at the same input power, more if counted from output current.


On most variant, input current will increase when you add load. Tuning the resistor value is needed to obtain the best output per input ratio.

And this device is never intended to provide you with free energy. To get real free energy device you may have to invest money as much as your lifetime electricity bill. However, this device is a very very good charger. If you need a charger, this device is better that anything else, especially if you consider the price to build it.

Thanks Sucahyo for detailed response!!

I have little doubt on whether I am getting any free energy at all, could you share the variant charger circuit so that I can have a look? I am really not much convinced how the charger can do fast charge w/o much o/p current.

Please put your valued comments / suggestion.

Thanks once more.

Hello everyone:

Bedini window motor if we adopt the half-bridge or full-bridge circuit can be a normal job? It will be more efficient?

From what I remember, many people sugest that window motor energy is not supposed to be use for other purposes other than self running.

I just built one of these fan chargers and i am really impressed. I rewound the coils myself using #34 as trigger and #30 or #28 not sure, for power. Coil is one long bifilar strand wound across the 4 poles in series, 50 winds per pole. First pole cw, second, ccw, third cw, fourth ccw. It draws about 450ma at 13v and rpm is very high. If i seal the front and back of the fan, the rpm more than doubles without any additional input. Voltage across 12v 4.5ah battery while charging reaches 16v and settles to around 13v when disconnected.

6.6 ohm trigger
2 ohm power
4 ohm 12v bulb trigger resistance to base

Anyone tried snapping the blades off of the fan? I just did it and the rpm must be well over 5000
