An Electric-Motor Turning An Electric-Generator Which Powers The Same Electric-Motor ?

   Could this create a self-running-device.
   
   SPECIFICALLY, what I’m wondering is, is there no combination of Electric-Motor and Electric-Generator that will result in the Generator,  outputting more electricity than was inputted into the Electric-Motor  ?

    And of course,  applying this principle to  Solid-State-Self-Running-Devices, I'm especially referring to the claim that the Figuera-Device  was self-running when it ran an  electric-motor.
    See my following post on the  Figuera thread :
    http://overunity.com/12794/re-inventing-the-wheel-part1-clemente_figuera-the-infinite-energy-machine/msg489301/#msg489301

   (  This also involves energy storage in spinning-electric-motors / spinning-electric-generators  )
____________
     So,

       - What if you used an Unusually-Highly-Efficient  Electric-Motor,  to turn an  :

      ( 1 ) -  Unusually-Highly-Efficient  Electrostatic-Generator( like a Wimhurst-Generator )
           Or,
      ( 2 ) - An Unusually-Highly-Efficient  Radially-Designed Electrophorus-Electrical-Generator
           Or,
      ( 3 ) - An Unusually-Highly-Efficient  Homopolar-Disc-Electrical-Generator
_________________
   Different Subject
   - Could A Device Be Made,  That Would Output A Bigger Electromagnetic-Field Than The Electromagnetic-Field Inputted Into The Device  ?
      What about instead of measuring  the electrical-input of the device,  and it's electrical-output,   you measured it's input electromagnetic-field inputted into the device,  and the electromagnetic-field outputted from the device.
     Yes I Know,    that the electrical-input should be the exact equivalent of the  electromagnetic-field inputted,   but what if there is some sort of  anomaly occurring,  maybe due to different materials used in one part of the device, to that of another .

According to Paul Babcock (him, not me), it is possible to build a motor that will produce one horsepower using less than 746 watts of electrical power.  If this is a true statement, you could connect that motor of his to a conventional generator.

A possible improvement to a complete self-running system is to use something like Jim Murray's Dynaflux Alternator instead of a conventional generator.  If those two guys and their devices are the real-deal, then it "should be" quite possible to have a self-running system capable of powering at least a few external devices or charge batteries.

Seems to me though, if one can build a motor that is not also generator and a generator that is not also motor, then these two concepts should be engineerable into a single device that self-runs and produces a usable output.  A good understanding of the necessary geometry needed would put these concepts on the map.  I know there is at least one member of this forum working on just such a solution.

Just a couple of things..

Back in the early 1900s my great grandfather had such a device, as my grandfather told me many times. He had 2 electric motors connected at the shaft and all the wires wen to small box with a switch mounted to it. Flip the switch and give it a turn by hand and off it went. He had shown it around town. Soon he was threatened by the gov and oil companies. Back then mind you.  In more recent years reading on Tesla, he was working with Westinghouse in Pittsburgh, 60mi from where My Great Grandfather lived, in the town I grew up. Great Grandpa also had dealings with Westinghouse on ideas to improve the air brake systems of the time. So it is possible he knew Tesla.

My Grandfather seemed to believe the answer was in the box with the switch. These days Im thinking it was in the motors, or at least one of them. Before Teslas A/C motors were mainstream, DC motors were well known and used.  So what Im thinking is that possibly at least one of the motors were AC. Had watched a couple vids on Tesla. One was a movie made about him in 1980, and the other was on the learning channel.  Something struck me, and it should have some time ago. The main idea of each vid was that AC was way more efficient than DC. So my question is now, does that efficiency occur in a properly developed AC motor, or even a gen?

If AC can travel greater distances on a wire with little loss as compared to DC, then what of a winding of a motor that has many turns?

As for my Great Grandpas setup on a plank of wood, if he had started it by hand, then I have to think they had some permanent magnets involved. And Id have to say they were not as good as we have today.  In the Tesla movie, near the beginning he was showing Edison a diagram of his idea for an AC generator. And the armature seemed to be a big magnet, showing no wires or brushes.  It was a movie, so we cant say that it was so for sure.



Now the other thing..

Been working with the mechanical resonance with coils and mags.  There was one configuration that when using the same magnets and coils for the drive side and gen side, I was able to get more voltage out(AC in and AC out) than the input.  Working on other mechanical configurations, I have come close to having an output voltage that is close to the input. All still using the same coils and mags for the inputs.  Im still working on these things. Trying different ways of having the coils interact with the magnets for best effect. And the best config to get the higher output voltage compared to the input voltage used the same mags and coils for the driver and gen, but the position of the coil to the magnet for each was a bit off to get these results. In the pics below I show the mag/coil config, then the device in motion with larger N52 mags, and the scope shot of the yel trace is sine input and blue trace is sine output.  The scope shot is not showing the freq of the device. For some reason maybe the noise was affecting it and the freq was just less than 10hz.

So Im in the process of determining if it is resonance that is creating the gain, or is it that a motor doesnt make a good gen, nor does a gen make a great motor either. As in, I position the drive coil for the max movement of the pendulum, then I adjust the position of the pickup coil to show the most voltage.  I know that a voltage measurement is not a sine of greater in than out, but to have an identical drive and gen coil, using identical magnets, to get more voltage out of the gen coil than what is put into the drive coil is not a common thing. And this is very low freq, straight sine wave in and no switching. Putting the 2 coils face to face without the mags shows virtually nill on the gen coil. Low voltages Im working with here.

So to conclude, 2 identical motors connected shaft to shaft is guaranteed to have less voltage out than what is going in. Like is it possible that maybe adjusting the brush angles of one of the 2 motors make it a better gen? ??? ?   Im going for voltage comparison here mainly because I think if the driver and gen are identical electrically and the same magnets for each, if you connect them shaft to shaft and you get more voltage out, then I think that is a great start. A barrier breached as far as Im concerned. If we need to run the drive motor off of the gen output, the gen needs to produce more voltage at the same rpm of the drive motor. And if the gen didnt require more turns of wire to produce that higher output voltage, that is a puzzle we have to solve. ;)

Back in the early days of DC motors, the stators were coils along with the armature. This creates a situation where the input polarity did not matter as the stators would produce opposite fields along with the armature, so either polarity of DC input and the motor would turn the same direction. So the DC motors of that kind can run off of AC input also. ;) So an old DC motor connected shaft to shaft with an AC gen could work if the AC gen can provide output more efficiently out at given rpm to the old DC motor. Been thinking on these things for many years and come up with more possibilities along the way. They didnt have electronic parts back then that in my thoughts could have been in the switch box to make the thing special. It would need to be something different in 1 or both motors.

Would probably be good to look into or even build some of Teslas AC gen/motors to see if there is anything more efficient about them.

Just thoughts of the day.

Maybe you simply need to find a DC motor having more torque then others with the same input power , due to permanent magnets used  ? Try to find the difference. Test shaft in both cases. If shaft can be magnetized/demagnetized quickly and strongly then it can allow some tricks , don't you think ?

Hey Forest

If we choose motors, one as a driver and one as a gen, we have to look at operating parameters to try and get the right ingredients for go. But then if we look at the efficiency of each, we are still below 100%.  Hard to say for sure. I would agree that the motor and gen need to be different from each other somehow.

Like I said before, some may put identical motors together showing losing results and that is that.  So this is what Im trying to point out, no, I dont think that is that, yet. ;D ;)

Some of these EV conversion DC motors have brush adjustments to change performance. So that is something to be considered. The idea that one particular brush setting is not the end all of settings. One setting performs good this way and another setting performs better in other ways. Otherwise why have the settings at all? ;)   This would also indicate that one direction may work differently than the other if there is a  brush setting offset. Like dc motors that need to operate in either direction have brushes basically centered in order to do so equally in either direction. Other motors that are only needed to operate in one direction ever, probably have a brush offset that complements the output of that predestined rotation direction.

I keep leaning toward the possibility of an AC gen and an appropriately designed DC motor with AC phase timing in mind. Possibly. Like for every AC phase peak, the DC motor is in an optimal position to use that  in the most efficient way, eliminating waste. This would most likely be a dc motor using windings instead of perm mags. Just ideas that havnt formed a complete picture for me, yet.

A long time ago I discovered that if I brought a magnet close to a running motor,  it dramatically increased it's speed.   Free-energy ?
 - As far as I remember it was a DC power source powering a DC-Motor out of a model-kit or slot-car.
 - I just assume that was was occurring was that when I brought my handheld magnet close to the motor, that it's magnetic-field strengthened the magnetic-fields of the magnets already in the motor,  and therefore increased it's speed.
   (  There were probably knobs or buttons on the power supply that had settings that I didn't understand enough about,  so that,  and possibly the specific angle at which I brought the magnet close to the motor,  means that it would be too difficult to replicate  )
(  I don't know if this discovery is just a commonly known scientific fact,  or a discovery )

 - I only discovered one other person on the internet that made the same accidental-discovery, they posted that discovery in very recent years,  and finding that persons research( webpage ) was so hard to find, that I have not been able to re-find it since  ) 
-------------------------------

A No Friction Generator,  On The Same Shaft As The Motor
 - Say you have a motor comprised of a single-wire which causes a magnetic-disk( or a hollow-cylinder-magnet ) to rotate ( a homopolar-motor ),   OR,  a stationary-magnet which causes a current-carrying-wire-ring to rotate( also a homopolar-motor ),   and also on the same-shaft,   you have another identical-motor to the first,  to use as the generator.
    The Reason I chose this generator is because it has no friction in terms of windings, since it's a homopolar-generator.
      Now,  What About if you multiply the diameter/radius of the generator by 2 or 3 times,  and yet somehow not increase the weight ( torque ) of the generator at all,  maybe by using kevlar-arms to increase the diameter/radius,   Would This Be Power Amplification ?

------------------------------
 
   Also, I still don't understand why Faraday used a mercury-filled( today they use brine ) bowl for his Faraday-motor,  since he could just have just induced a disc-magnet to spin( maybe not available back then ), or induced a current-carrying hollow-disk to spin etc,   and why it's still often commonly replicated today,  using the liquid.
    I assume,  that it's because it was the first discovery/version of a motor.

     But now I see these popular DIY very-simple Homopolar-motors made of a single battery, a single small-flat-disc-magnet,  and a piece of wire.
      HOWEVER,  The Thing I don't understand is why they run the current through the permanent-magnet( small-flat-disc-magnet ),  I don't get why you run current through a permanent-magnet,  which I think also occurs in the original Faraday-Motor,  it seems like a very strange thing to do.
-----------------------

   I don't know why people use anything other than DC-curent ( as smooth as possible, as similar to from a battery as possible ) for their research for any devices on this site, it makes little sense to use anything else.   
      -  I guess there may be some applications where AC is appropriate.
         But specifically, I refer to devices like the Figuera-Device.

Adding the magnet to the motor does increase the stator magnet field, and if you flip the magnet over to the other pole it should slow some.  As far as I know the stronger the permanent mags in a motor, the more physical output per input to the armature. Which is logical, as if the internal magnets were replaced with very weak mags, the output will diminish while the input remains the same as before. So there should be an efficiency increase using larger/stronger mags.

The mercury was used to replace the brushes on the outer edge of the disk. Reduction of wear on the rotor edge and lower friction as the brushes needed to be tight against the rotor due to high currents produced and the necessity of very low resistance at the connection. And the brushes on the outer edge has more friction braking power at the outer edge of the disk.  I wouldnt feel comfortable using mercury unless it were a sealed unit that did not allow any to get out of the casing, None.

   The device you mentioned from the early 1900's of your grandfatrher,  and,  the Figueras-Device,  and there were other peoples devices. 
    They were suppressed,  as people often state,  but I notice that people never state that they were suppressed by the electricity-providing companies ,   which I would have thought would have the most to lose from an  overunity-electricity-generator..............
     And, in your grandfathers and Figueras and the others day,  battery-powered-electric-cars( all electric cars ) were at the height of their popularity in the history of electric-cars,  you'd think the electric-car industry of the day,  would have had an interest in bringing overunity-generators to the market,   not to mentioned points in history where countries would certainly have used overunity-generators due to circumstances etc.
______

   Below,  are the  diagrams of 4 or 5  electric-motors  I designed to solve a  historical-technical question ,  which was raised by   gravityblock  in the following message below ( different thread ),  the link takes you straight to the exact message posted by  gravityblock   :

   http://overunity.com/15978/new-reactionless-motor-from-india/msg459408/#msg459408

   It involves   'N-theory'  vs  'M-hypothesis'.

   The Challenge,   was to design a fully rotating version of the  M-Device DIAGRAM in gravityblock 's   post .

        And,  he said somewhere,  that a solution to the puzzle would be a much more efficient-motor for the market,  and that it's important that the number of flux-lines( of the conducting-wire, or permanent-magnet ? )  cut by the  conducting-wire, or permanent-magnet ?,  are minimized to just one.

    (  when I replied to his post, I hinted at my solution, without giving it away fully, I gave a solution which was slightly different to the one I had in mind,   but,   I have one or two ways of proving the exact time and day of when I thought up my solution  )

    Please Note : 
        -  In My-Diagrams below,  they are  Disk-Magnets,  being spun by the current flowing through the wire .
        -  And,  where the conducting-wire makes an exact 90-degree turn( an exact right-angle turn ),   that maybe that could be  'Curved-Turn',   and then  'Maybe No'  flux-lines( of the conducting-wire, or permanent-magnet ? )  would be cut by the  conducting-wire, or permanent-magnet ?
     
   However,   now,  I'm wondering if my electric-motor designs would actually rotate,  and I don't know if they solved the  historical-technical question .

Havnt built one of these dynamos. But what would interest me is, if the 'magnet spins with the disk', and we get output, then is there drag on the rotating parts when the disk electrical output has a load on it? If it does have drag, what is it dragging against? If it doesnt have drag, then we have a gen that needs no more input with a heavy load than when the input spins the device with no load. Id say thats a good thing.  If it does have drag, again, what is it dragging against? And if it is say the aether that is the drag on the system, then we have a system that 'physically' interacts with the aether.  So what interests me there is the possibility of using that interaction to create propulsion, of a car, bike, plane, etc.

What if we could develop a device that could push/pull on the aether? I might be scared to think about how pushing and or pulling on the aether with enough force to say move a man on a bike, may affect things around  the device doing such. Might not be a good thing. Dunno. Now imagine with the force to move a car. Makes ya think though. Prepare for the unexpected possibilities.

 Please Note : 
        -  In My-Diagrams of the Electric-Motors in my previous post,  the Circles are  Disk-Magnets,  and the Lines-Labelled-X, are wires that have DC-Current flowing through them.
        -  The Idea is that the  DC-Current flowing through the wire,  should cause the  Disk-Magnets  to spin.
        -  And,  where the conducting-wire makes an exact 90-degree turn( an exact right-angle turn ),   that maybe that could be Replaced with a 'Curved-Turn',   so that  then  'Maybe No'  flux-lines( of the conducting-wire, or permanent-magnet ? )  would be cut by the  conducting-wire, or permanent-magnet ?
     
   However,   now,  I'm wondering if my electric-motor designs would actually rotate,  and I don't know if they solved the  historical-technical question .
______________________

    Your reply gave me another idea for these motors however,  like replacing the wires that have DC-Current flowing through them,   with the DC-Current-Carrying-Disks used in the Faraday-Disk-Electricity-generator.

______________________

   Your Aether-Drive, could maybe be like a jacobs-ladder which pushes against the tiny-particles that make up electromagnetic-energy and photons ,  except that this jacobs-ladder would have layers/sheets of electricity maybe moving through blocks of crystals measuring 3x3 feet,   and the stability of the craft could be provided by the gyroscopic-force of the rotating-overunity-generator.

This would make this idea the cheapest household electricity source,global
(included Fraunhofer-Institute " 2050 forecast" solar cell KWh price down to 2 US$cents fall) :

Only published in Germany 1977,from India !

The advantage : builder free RPM decision cause it is -not- a rotoverter !
Higher RPMs = cheaper production costs,generator mechanical friction will in future become neutralized by nanocoating and surface ablation treatment.
The generator starting cycle will be activated by hand/rotating wheel or starter-engine ! 

Only one inventor is citing this Mukherjee- invention idea.

from the decription page :
As a result, the voltage output of the permanent magnet ac generator taught by the present invention is relatively constant, from no load to full load. Thus the present invention thereby achieves voltage regulation of a permanent magnet synchronous ac constant speed generator without the use of an external regulator connected to any wound field.

Good for a cheap and simple wind/water power system.

Here some information about the production process of high power density electric transducer =
motor/generator,now in legal "open source" status :

https://worldwide.espacenet.com/searchResults?submitted=true&locale=en_EP&DB=EPODOC&ST=advanced&TI=&AB=&PN=&AP=&PR=&PD=&PA=unique+mobility&IN=&CPC=&IC=&Submit=Search

f.e. https://worldwide.espacenet.com/publicationDetails/description?CC=US&NR=5319844A&KC=A&FT=D&ND=3&date=19940614&DB=EPODOC&locale=en_EP
Total weight = 15.0 (pounds)
 This motor delivered 16 horsepower at 7800 RPM in preliminary testing.
~ 1,5 - 1,75 KW/Kg

to compare with the LAUNCHPOINT Halbach-array motor
http://www.launchpnt.com/portfolio/transportation/halbach-electric-motor

The difference will be - at first- the production price :
 the Unique Mobility(now UQM  https://www.uqm.com/home/default.aspx  ) version could
become produced for less than  1/10 .

1 KW/Kg/10US$ is realizable = commercial low cost

                            https://www.google.com/patents/US7888839
 As a result, the power capability increases from 23.25 Hp to 40 Hp, providing the highest power rotor magnetic design configuration. In low inertia requirement applications, it is also contemplated that a Halbach motor magnet array with non-magnetic rotor portions, could alternatively be used. However, this configuration results in significantly higher costs that are typically not compatible for most commercial applications.

The need is a modular 3d printable high power density motor/generator design .

       Need Decreased Cost     – bring electronic propulsion systems costs below $8/kW
              Need Decreased Weight – bring specific power to 1.3 kW/kg by 2015
