Lockridge Device - Peter Lindemann

[wantomake]

Still trying!!

thanks mbrown,

I've rewired two pm treadmill dc motors and put a commutator on the output shaft; but had little success with it.
Got one that would produce voltage on the second set of brushes but only got very hot and burn places on the commutator. Even with the MANY different settings, wire gauges, and all the reading I could do. I think the best is try the original way.

@Robert49,
Did you get to ask Henry anymore about what he saw of the original machine?

zero cogging generator by FTC Energy

Hadn't read the last several pages on this topic, but as I recall a highly efficient motor had been developed, and the generator was an open topic still. As far as efficient motors go, QM Power is in that business, by buying Flynn Research, and sneaking in some OU features? Well its all in magnetic flux switching there shown here:Switching Permantent Magnet Field. But great job as I remember on just tapping the bemf (or cemf?) getting great performance. So a gnerator is still needed right? Seems an inordinate concentration on getting a dyno constructed. My main question is has anybody seen FTC Energy's zero cogging generator. They are 100% in production I think of a system that can be rigged as OU but it is not obvious, until you call Joe and ask about it. Definitely getting 150% OU. So I poked around their patent and presentations and I think I started getting an inkling that they may be using flux switching to get the zero cogging on the magnets. Think I might buy the NG system and as emergency off-grid capability and run my meter backward. When you look at their wind turbine, you say how stupid are those propelor windmills. So the generator to this Lockridge setup maybe could reverse the idea of using flux switching for a motor to a generator?

This thread is device specific so the devices you mention are not really relevent but as I have postulated before it is possible to parallel path a universal type motor. If you want to discuss this maybe we can do it in this thread http://www.energeticforum.com/renewa...ath-motor.html

I am no expert on generators although I believe the generating section of the lockridge was different to the link you posted

This is my reply to a post on http://www.energeticforum.com/renewa...tml#post209377 I think it has more relevance here so that is why I have placed it here too. There hasn't been much activity on this thread but it does not mean that the thread or the research is dead.


"I am familiar with finite element analysis although the only ones I have used is for stress and strain and for designing elastimeric seals.

I was thinking more about the electrical circuit and the geometry. I haven't researched Thane Heins, maybe it is time I did. I have managed to use inductive compensation to increase current flow in the motor while also using that current to charge a capacitor which will be used for the next pulse. Recycling it if you will.

If you remember how farmhand turned a universal motor into an induction motor this shows inductive compensation/transformer actions.

Inductive compensation is a transformer effect and if configured correctly can increase current in the motor in the same way a loaded secondary increases current in the primary in a transformer. This increase in current then increases the flux in the armature producing more torque. In a transformer the reverse is true because the secondary is wound over the primary. In the motor all the flux has to pass through the armature before it reaches the secondary thus increasing magnetic flux in the armature.

In a standard motor this compensation coil is opposite the power coil but I am experimenting with placing it somewhere close to 90 degrees. Some have shown in their videos that a shorted coil in this area can cause an acceleration so I am investigating it. A shorted coil is an inductive compensation coil. In their videos they had an open magnetic circuit where I have been using a closed one but now the geometry of the stator has to be taken into account. I believe this may be one of the reasons for the splits in the case of the Lockridge.

This is more appropriate to the lockridge thread so I will also post this there"

"Squires suggests that the voltage needed to cause current to flow in the motor coil pulses not be provided by the supply. Instead it can be provided by the inductive kickback from a large choke that has a large mass of iron. In the lockridge we have a trifilar coil wound round the motor so it is now obvious to me that this has to be one of the main functions of the trifilar coil.

Not in the video but I believe relevant, is the fact that the motor coils, generator coils and trifilar coils are all wound on the same mass of iron. When an inductor that has an iron core is charged, that energy goes into the iron. If the iron was charged by the motor function, little or no more energy is spent on the iron during the transformer and generator functions therefore these functions should be more efficient than you would normally expect. If it is the choke that charges the iron and that choke is maintained in a charged condition as squires suggests, could it be that the motor function too is more efficient?"

lotec this might sound silly. but would it be possible to wire the drive coil like a step up transformer with twin secondaries oriented in opposite directions with diodes so that one will induct and try to neutralize the drive winding flux and then the other seeing that change will induct and try to re-establish that flux but now there is a stepped up current to feed back into the motor? or even lose the drive coil and have a low lenz drag generator coil or even make a motionless electrical amplifying transformer?? I want to look into this if i ever get the time.

Yes it is possible to have more windings on the output coil to step up the voltage of the transformer effect, this would also increase the voltage generated through lenz. This may actually be the case in the lockridge device but as yet I dont know. You could also have twin secondaries but they would need to be in the magnetic circuit.

I don't really understand the second part of your question

[wantomake]

I agree

mbrown,

I think this is key. I thought of building a large inductor and cap outside, but not around the motor. But saw that the transformer effect would take place with the split in the core of that old generator in the vid with John Bedini.

I have the same 1950's generator and another three (different types) to work with. I don't have the means to replicate the choke and capacitor as he said in the video. That's a lot of copper sheeting!!

Still here and want to help if I can.

Hello Mbrownn

I have Disclosed exactly this now recent release by Mr. Squire, on this same Forum, exactly same experiments and tests that you are mentioning in the statement above, when I started My First Thread back in February 2012..meaning, running any Symmetrical Motor off a Coil reversed feed, and regulated/filtered through two Diodes, being pulsed by a simple 555 timer oscillator, here is a simple Diagram I posted back then:

Happy Motor Diagram

Latest experiments also have proven...there is absolutely no need to have a "large mass of iron"...but just ...Air.

Further on, many Members here have tried that experiment very successfully...including Member Netica...where we could see on the video below, an Air Core...and note how Amperage does not increases when He adds a mechanical load to Motor Shaft...that video has been out since June 2012...

Thanks for the link and the insights.
When i read about you discussing the transformer effect in motors it got me excited because of an idea that had been floating around in my head about the transformer effect in generator coils. A pair of coils that can only conduct in opposite directions from the use of diodes. As the magnet approaches it tries to induct both coils but only one can conduct. This becomes the primary. As it conducts it makes a flux that slows down the rotor. This flux then inducts the other coil and current flows in the opposite direction(secondary). As in a standard transformer the flux from the secondary neutralizes the flux made by the primary(which creates lenz drag) and also lowers the primaries impedance so more current can flow through it.
When the magnet leaves the coil the same thing happens all over again except that the two coils swap roles. You got me curious about what might happen if a motor coil were wound over the top of these. I wont waffle any further because yet again Ive managed to pick the wrong thread for it and I dont want to become a nuisance. Thanks again for the advice and ideas you have given me so far.

Yes any tests you do will help. You can make up a bank of capacitors and making the trifilar coil will be relatively easy if you can get the wire, getting its inductance right might be more of a problem

Thanks for the reply UFO, points noted.

I think the Iron depends upon what you are doing with the motor. If you have very rapid switching and high frequency, Iron may not be needed but that isn't always practical with commutator switching. either way testing will reveal what is best and the more people that do it the more certain we can be of the results.

If you wind one coil over a second coil the flux does not have to go far to transfer its effect into the secondary wire therefore the flux in the core is reduced. If we separate our coils along an iron core the flux has to pass along that core to reach the second inductor

Now if we place the armature of a motor in that iron core the flux has to pass through the armature causing rotation. if we draw more current from our secondary winding this causes more flux in the armature and therefore more torque from the motor.

I think winding secondaries on the power coils will reduce the motor torque and so will be counter productive.

[Robert49]

Very interesting, could you ask your friend more about it?

Sorry i did not see this before, I dont have an internet connection at the moment

Hi guys.
I just talked with my friend Henry and asked if he remembered more about the device he saw during the war.
He says he saw the man in charge of it hand crank the device and it would turn and accelerate for ten minutes (he thinks there was probably a flywheel on the generator) and then the guy flipped a switch and they heard a loud noise and the light came on.

Don't know if this helps but here it is.

Good luck to all.

Robert
