Lockridge Device - Peter Lindemann

[Hiwater]

Mbrownn, I tried yestyerday using one extra positive brush on the commutatorwith a few bulbs as a load. It does remove just about all the armature reaction at about 3000 rpms. This was dome on a stock GM generator, with out any modifications.

As for a motorising side of the generator this can be easily done with a couple quick modifications. I have done this using other starter coils from another old starter. I havent done the modification with the stosk feild coils to see how they would function. Will try to do this sometime today. (NEW IDEAS CREATE NEW ENTHUSIAM)
The ratio of turns is what ever we want to make just so they will balance.The star wound armature, would have three balance coils for the armature. Thus the triffilar coil. working with alternators these balance coils bring the input down and out put up.
Removing the armature windings will be a challenge, can be done though.

Coils

Good morning everyone,
I follow this thread as much as I can and get quite a bit of infomration from it...thanks
As you may or may not know I am actively working on a Watson machine and am drawing to adding a coil to cath emf when when switch is opened.
This coil would be in series with one terminal of the swicth and the positive terminal of the battery.
My question is would you recommend a bi filiar coil or a simple mono directional coil?
Also should there be an iron core or air?
Thanks
Bizzy

Nice to see you posting here. Sorry I can not answer your questions. I am sure
someone here probably can. I would also like to know what would be the best
answers for your coil questions.

Is your generator star wound? How many poles does it have? I ask so that I can understand what you need to do with the circuit.


The ratio of turns could be anywhere between 2.5 and 5 to one but depending upon how we use the trifilar coil it could be different.

There may be a gain in the trifilar coil depending upon how it is used but at this stage I am not certain which configuration it has and where it is placed because I need to do testing.

I just need to clarify something here, Is it the Inductive kickback you are trying to catch or the generated forward emf that follows it?

A circuit would help

Atually both would be nice but but i think catching the inductive kickback would be the best.

No, its a stock series wound 12 volt delco generator armature. It has 2 feild poles. I have added a starter feild coil in place of one of the generator feild coils. This brings up the rpm to a higher rate. But then i dont have the voltage. So going to change that back to the original generator coil. To see where my voltage is at. Then go from there. What rpm do you think we would need.

The good thing about inductive kickback is the motoring action it gives while ever it is flowing, almost doubling the motor power in some cases as in PWM circuits. Catching it is simple, a diode on the output side of the coil and a capacitor to store it Bedini style. Catching it and using it in the motor is slightly more complex.

You didn,t post a circuit so I cant tell you where to put it in your device but this is a simple way of doing it however you do need bipolar switching on your coil. Circuit Simulator Applet

The principal here is to subtract the recovered energy from the input requirement so if your motor requires an input of 100w and you can recover 50w you now only need the recovered energy plus 50w from the source for the next pulse.

If your motor was 70% efficient, you may get close up to 140% using PWM but now feeding the 50% recovered energy back to the input we have in effect 140w output for a 50w input.

Lets do the maths,

input to motor 100w
claimed Motor efficiency 70%
recovery 70% of 70% of 100w = 49w
Motor output 70w + 49w = 119
Capacitor efficiency on recovery 80% thus power available for supply = 39.2w
supply from battery 100-39.2 = 60.8w

COP 119/60.8 = 1.95

In truth, motors quoted at 70% efficiency usually is already under PWM and so their real efficiency is much less

input to motor 100w
real Motor efficiency 50%
recovery 50% of 50% of 100w = 25w
Motor output 50w + 25w = 75w
Capacitor efficiency on recovery 80% thus power available for supply = 20w (on a real test I got 17w from a 49% efficiency motor)
supply from battery 100-20 = 80w

COP 75/80 = 0.9375

Once we have a motor that is truly 70% efficient we can have a self runner with a very high efficiency generator on this circuit.

Ahh so effectively it is a Universal motor with a standard winding. The approach is different and is what my earlier posts are about.There will be little power in the brushed recovery when compared to the input.

This is how I originally thought the circuit would work Circuit Simulator Applet

Yes we do get an overunity in energy in the motor when compared to the input but the problem is the gain is in volts and a motor works on amps. the result was a motor that had low efficiency and produced a lot of heat. It could work if the rotor and stator was completely rewound with many more turns but the same resistance but of course we could not fit that in the frame.

Here you can see some of the experimental circuits I need to try with an impedance matching trifilar coil. this will convert voltage gain into the correct volts and amps for the motor but where do I tap the inductive kickback? ( I have placed diodes in the possible locations and not all will be used) the sim won't run it easily so only real testing will do and this takes time and money.

I don't have all the answers yet but I am working on it so while I am not posting too much about it you can see what I am up to.

This is the coil of armagdn03

Circuit Simulator Applet

If you want to give it a go I suggest two microwave oven transformers connected back to back as they can handle the power but be very careful we are talking lethal power here.

The frequency of the switching needs to be the resonant frequency of the combined secondary windings to get the voltage gain we are looking for.

Hi Mbrownn

I noticed in Teslas patent 464666 that he used over the field coils an overwinding of fine wire, connected to a secondary field coil, again of fine wire, this using the inductive spike to further drive the rotor. Would this sort of arrangement increase the efficiency as you indicated above? Twice the turn for 1 input.

This patent is for an alternating current motor so I think it is different, but inductive kickback can be collected this way and I believe it was used in a Gray motor.

Mbrownn. I dont like those mot transformers. I got hit with the 2200 volt off one of the capacitors a couple yars ago. It fixed my shoulder though, felt pretty good for a long time.
If we look at the armature like the earth and it equater, with the north and south hemisphere, cw and ccw forces, all the lines converge at the cemter. this may be where most of the power can be released. Maybe we have to use two north poles and pull the power off the neutral plane with one wide brush or just off center with rotation on one commutator section each with one narrow brush so each brush is in one hemisphere.
Maybe will have to study nature and how the earth spins on it axis in side a magnetid field.

I agree those transformers are dangerous.

My schematic shows a much simplified rotor winding but to all intents and purposes it is like a real rotor, if you imagine how the commutator is passing over the segments you will see that it is two coils opposite each other on the rotor that will create a spike but this spike will mostly just pass around the rotor and we won't be able to collect much at all.

These rotors are designed to minimize the effect we are looking for. The best method is to treat all the coils and rotor as a single coil and pulse the whole motor externally.

If you can wait a little time, I will be rewinding a rotor and doing some tests to make a comparison and I will post the information for you. This will be more like the original device.

Oh no another rotor rewinding competition

Is there any questions

@All,
I have Norm Sides up to visit me he is the original man that relayed the Lockridge device to me. Is there any questions you want me to ask him?

Could you please ask if he has heard of any new information about the device,
since the release of your's and Peter's videos. Or any information about old
Lockridge devices being found anywhere.
