Latest Update

Input 8v 30 amps, output "about 104-110 volts. It will lite 2 100 watt bulbs pretty good . The third one brings the voltage down so all three are at about 3/4 illumination"

So if the input is 240w and the output is in excess of 200w we are getting quite efficient now. At this stage we have not got any recovery circuits. The astonishing thing is the voltage gain.

I had some bad news this morning, someone has been in my workshop and stripped the copper wire out of all my motors, transformers, variacs and everything to do with my research. B!@#*!rds The batteries and anything made of aluminum has gone too

Hi

Sorry to hear that.
The world is made out of 50% idiots, 30% "bass holllls", and then there's the rest of us. I may be wrong but it sure feels like this.

Luckily the motor we are testing was not in my possession, so the work goes on.

The interesting thing about the voltage gain is where it is coming from, it has been noticed that there is arcing between the commutator and the negative brush preceding contact. We believe that the armature is charging up to the KV range. Trying to establish the cause, as we are only supplying 8 to 20v we studied the operation of the armature.

The armature is a standard unit that we believe to be lap wound. If this is the case then we have effectively a loop of coils going around the armature. As the brushes move off one commutator segment to the next we have a condition where one of the coils in the loop is shorted. We believe that this coil shorting is causing a change in inductance in the armature allowing it to charge under low inductance and discharge under high inductance causing a dramatic rise in voltage.

More replications are needed to confirm or disprove this theory.

There is a lot more to this than meets the eye. If anyone wishes to join in with these experiments, I will bring them up to speed.

This may also relate to the 3 battery generating system.

Recent reading has explained to me that the purpose of a compensation coil is to prevent this anomaly. As we use the inductive compensation to power our load we have an extra resistance preventing efficient transfer of energy from the armature, the result being a build up in the armature.

If this is indeed, part of the how the lockridge worked, then we know the purpose of the extra brushes in that device.That is to draw off the high voltage out of the armature.

Just to add my thoughts on the lockridge. I am very intrigued by this motor. Doing more research on it I came across a Tesla patent for electro magnetic motor:

Tesla Patent No. 381,968 - Electro Magnetic Motor


The DC motors of today that I've taken apart are definitely not wound like this. Each commutator has a link to the next...

Maybe the style of winding's on that patent are the key? That way we wouldn't need to find an old DC motor but be able to either create our own or modify a newer and larger model. I can only speculate that the winding style would create a lot of arcing, but efficiency should be good. If the brushes were very thin like the ones on the lockridge device, I believe there would be a type of diode effect which would take place as the commutator sections passed by the brushes. This would be a high voltage discharge and might explain the copper wrap capacitor around the device itself to capture it. The diode effect could give a similar effect as that of the plasma ignition circuit. The brushes would obviously need to be modified and timed perfectly so that as the commutator rotates, one section is barely touching one segment, but the other brush has already passed. Effectively creating the open circuit and allowing the spark to flow into the capacitor. At 5000+ rpm this would be happening extremely fast of course, and the high voltage coming from the capacitor would probably blow anything plugged into it. Perhaps the tri-filar design was to step down the high voltage into something more useful? That, and it could behave like the impedance matching coil setup of John Bedini in order to match the load and not 'kill' it?

Just speculation but I'd like to hear everyones thoughts. I never knew the old DC motors had to energize their magnetic poles in order to charge like our alternators do today. This adds an interesting aspect. Correct me if I'm wrong, but even with a pull cord, would the device even power up? The only thing I can think of, is that the switching mechanism with the brushes would perform an oscillation function and somehow use the earths magnetic field to create a small 'kick' and then those kicks would build up and the device would slowly speed up until it reached a happy speed.

I'd love to know if the coils were stock or if modified. I'm beginning to think modified for high voltage, but what do I know. I've contemplated buying an old delco remy generator/starter off ebay but would it be worth it? I'd probably toss it on the shelf after a few weeks of playing with it.

Edit: Just to add, going through Tesla's patent again, he talks about there being a generator and motor within the one design? Very intriguing. Nothing about self sustainability, but maybe there is some clues on how one could achieve that result?

Yes an interesting patent.

Yes this is known as lap winding and the old method is a form of wave winding.

Maybe the style of winding's on that patent are the key? That way we wouldn't need to find an old DC motor but be able to either create our own or modify a newer and larger model. I can only speculate that the winding style would create a lot of arcing, but efficiency should be good.

Yes, I have wound such a motor and although the donor motor was designed for 220v my rewound one would run on 4v, at 20v the arcing was so bad it was burning up the commutator and brushes. Placing a second set of brushes with the correct timing I was able to recover a large amount of the input. This is the configuration I believe was used but I cannot be sure as I am now able to get a similar situation with a lap wound rotor that is unmodified. I never measured the mechanical efficiency.

If the brushes were very thin like the ones on the lockridge device, I believe there would be a type of diode effect which would take place as the commutator sections passed by the brushes. This would be a high voltage discharge and might explain the copper wrap capacitor around the device itself to capture it. The diode effect could give a similar effect as that of the plasma ignition circuit. The brushes would obviously need to be modified and timed perfectly so that as the commutator rotates, one section is barely touching one segment, but the other brush has already passed.

You are correct but this effect would only occur above a pre determined speed.

Perhaps the tri-filar design was to step down the high voltage into something more useful? That, and it could behave like the impedance matching coil setup of John Bedini in order to match the load and not 'kill' it?

The trifilar has many functions but to step down in the manner you suggest is less likely although an impedance matching ability may well be a part of it.

I never knew the old DC motors had to energize their magnetic poles in order to charge like our alternators do today. This adds an interesting aspect. Correct me if I'm wrong, but even with a pull cord, would the device even power up?

Not without a supply battery

Correct

and somehow use the earths magnetic field to create a small 'kick' and then those kicks would build up and the device would slowly speed up until it reached a happy speed.

Unlikely

I'd love to know if the coils were stock or if modified. I'm beginning to think modified for high voltage, but what do I know. I've contemplated buying an old delco remy generator/starter off ebay but would it be worth it? I'd probably toss it on the shelf after a few weeks of playing with it.

Do it, there is so much for you lo learn. We have already got one of these delco motor/generators running at 8 to 20v at 30A and producing 80 to 110v at 2+A as an output. We have only slotted the case and have no recovery as yet but there are many interesting things happening such as Kvs building up in the armature.

We are using 4 generator coils with a slight adjustment in their position and only two brushes at the moment, everything else is standard except how we connect the windings up.

With this build up of voltage in the armature it may be possible to use an unmodified one so we have to test this. At the moment there is only one person doing it so if you also joined in with us, we could confirm our results and double the speed of progress.

How to increase sparking on the commutator. or decrease it...

This is a very imporant primer that any newbie should watch.

[Tinmanpower]

Well i would love to be in on this one,but i havnt payed any money to peter for his book,or been to one of his confrences-nor do i intend on ever doing so.
As Peter clearly stated that no one is to post on this thread(although it wasnt started by him)unless you have bought my book-i guess im out.
But if some one would start a thread about the lockridge device,that isnt dictative as to who can contribute to the thread-then i may have something you all might like.
And yes,it is from ww2.

Hi Tinmanpower

I've started a new thread called Other Lockridge theory's. Hope to see you there.

Hi guys.

I saw my friend Henry this Sunday and we talked a bit about the self-running generator "Lockridge device".
You have to remember that he was born in 1938 so he was only eight years old in 1945.
They had these in underground bunkers just for lighting.
He did not interact with the machine but he remembers clearly that the device was started by hand with a pull cord. Then the device would accelerate slowly , he does'nt know the speed but he says it was running possibly between 1000 to 3000 rpm and would hear a clicking sound , not fast but steady.Then they switched the lights on.

Not a lot of help but he confirms "it did work"

Wish I could help more.

The slow acceleration may be significant

[john_g]

The slow acceleration may be significant

I think it is significant also - seems to me that the machine is only just about generating/reusing energy to just keep itself going, making only a very small energy gain with each revolution.

[mbrownn]

This is about making the motor/generator part of the lockridge

Its quite simple really but making it happen takes a little work. You will need an AC or half way rectified AC or a pulsed DC supply for it to work although in the final device it will be pulsed DC

You need a 4 pole universal motor, these usually have four brushes on the armature but we will only use twoat this stage.

The 3 o'clock, 9 o'clock coils and the armature are powered in series through the brushes at the 3 o'clock and 9 o'clock positions. The motor is in magnetic lock when operated this way and will not turn.

Now take the 12 o'clock and 6 o'clock coils and connect them to a low resistance load. the motor may begin to turn
To improve motoring performance the 12 and 6 o'clock coils may have to be advanced or retarded to find the Ideal position.

A varying supply has to be used or you will not get transformer action. The transformer action powers the 12 an 6 o'clock coils giving an electrical output

As the motor is in magnetic lock, no BEMF is generated, even when the motor is turning little BEMF can be generated.

The motoring force is caused by the flux being compressed at one side of the 12 and 6 o'clock coils.

The motoring force is not good at this point as al the coils are interacting with each other and the flux is being shorted

To further improve motoring action we have to split the case length ways, just as in the lockridge device at the 1.30 and 7.30 positions and with fine tuning of the position of the 12 and 6 o'clock coils good motoring action takes place.

As the motor is now turning BEMF or forward generated current is occurring in the 12 and 6 o'clock coils.

An amplification of voltage occurs in the output.

See drawing of magnetic circuit

2-pole universal motor, bottom coil disconnected.

Pulsed at about 1000 RPM (16Hz) using 555's, 33% duty cycle and a relay. If I have time, I'll post all of the details to EF tomorrow. Otherwise, when I return in a week or so (remind me :-).

Top trace is across the modified motor. 50V/div.

Middle trace across the 2nd coil (disconnected, acting in transformer mode). 5V/div

Bottom trace is the dual-555 driver circuit hitting a relay, switching 24VDC pulses across the motor (major sparking across the contacts of the relay).

400V spikes on the motor side. 10X less on the 2nd coil side.

I also did scope shots before modifying the motor and not much was different (400V spikes). The results were essentially the same as the top trace. (The 400V spikes are barely visible, but they are there).
