quote from inventacom says "motor that has to be fed from initial batt start to being run from converter. There is a certain setup in controls to achieve this as well as recharging the batt. Once the battery reaches a full full charge capacity, the battery is cut off and the converter becomes the main dc power source. The converter is connected to the gen head.  When the gen head reaches the correct rpms, the converter is powered on which then recharges the batt and then takes over to run dc motor. The unit then runs in a circle from gen head to converter to dc motor that provides the needed rpms to gen head "

So the Gen head feeds converter/battery charger which feeds fan motor .

I see we need to know which fan motor it is .All the fan motors  i am seeing don't give rpm or amps. It looks massive like a house fan size in the pics from inventacom.
I might just get this gen head on credit though because of the low rpms needed , been wanting one like this for a long time for ham station/house  backup . i got plenty of motors ..

I don't know if this horsepower to kilowatt conversion  chart is useful or not :

@gadget & Ematrix Thanks for the email, I've got the files

@gadget I've got a fan motor from a company but it isn't listed in their current stock models but this one shows rpm's and amps as well as the torque.

A generator of the size that inventacom uses requires an engine with the following specs to run it:

Engine Minimum 11 hp
Engine Speed 3540-3720 RPM
Torque 16 ft-lbs

This is where I'm in agreement with Vince that even with the secret sauce you can't convert the fan motor's inadequate torque to meet the generator's demand even if you geared it to reach it's lowest rpm's requirement.

16 ft-lbs = 3072 oz.in and as you can see on the graph in the picture the more you load the fan motor you get less rpm and more amps required and that is just at approximately 1/30th of the required torque!

As far as I can see you'd need a much bigger fan motor than the one I'm looking at

Hi folks, Hi fatbird, that kipper setup almost looks similar to what garry stanley was testing, using batteries.
I converted the html into a pdf, in hopes that it may shed more light on this device topic, which i find intriguing.
Here is a download link to Garry Stanley pdf.

More testing! Isolation and voltage regulation. (Thanks Gotoluc)

I changed the generator to a 90 volt .3 amp dc motor to see if
I could isolate the power for a future feed back.  I know the motor is on the small size but this is just to prove that isolation is possible without killing the source. Gotoluc had suggested reverse feeding a ac computer power supply with dc to match voltage to the load and isolate them from each other. Hey Gotoluc you were right! it will reverse feed and output corrected voltage
With the smaller motor acting as a generator it will easily spin up to design rpm and the little fan is running at load rpm 1700.  The generator puts out about 139 volts and thru the power supply in reverse and it puts out 12.1 volts while the fan motor is drawing about 6 amps 12volts. I can power another load now without the fan motor dying. I tried loping it back to the fan feed and got a few extra rpm out of the motor but the generator does not produce enough current to sustain the drive motor.

Hope I'm not boring anyone, with all these tests!

@ Skywatcher,   That download site wants to download a dangerous executable file before it will download your PDF.
                          Please post that PDF file right here on this thread, just as if it is a picture.  Thank you for sharing sir.


@ Vince,  Thank you for sharing your setup pictures.  Another thing you might want to try is to couple the shafts of 2 identical Radiator
                Fan Motors, using a piece of hose, shaft to shaft.  One would be the drive motor, & the other the Gen.  The output will be
                DC, but there is nothing wrong with DC.  A cheap 12V to 120V Inverter can produce the AC, if & when needed.  LOL

                Vince, the reason your picture above isn't showing up is because it's over 600 pixels.

Hi Vince,

I apologize to ask: Did Gotoluc tell you the isolation and voltage regulation on some of the forum threads or maybe privately?
Because yesterday I wrote to you the same as an answer to your question (including the PC power supply) in this thread here:
http://www.overunity.com/12724/free-electric-multi-use-motor-home-gen-car-motor-boat-motor-lawn-mower/msg337337/#msg337337

I do not mean to grab credit from Gotoluc, his excellent activity is known for years here and on other forums and of course I do not look for "fame" with this notice either.   

Keep up your good work!
