Lockridge Device - Peter Lindemann

[mbrownn]

Hi Paul, as you are using a 2 pole motor you might not get what we have. The device is simple but the interactions are complex.

We have a great increase in voltage on the unconnected winding.

what your trace does show is there is a transformer action. Put a low impedance load on the disconnected coil and shorten your pulses by 2/3rds.

better still get a four pole universal motor and ill tell you what to do and the basics of this is in my previous post. We need replicators to confirm results.

Remember this is just the motor/generator so don't expect great efficiencies yet. There is little BEMF on the motor so it draws high current.

We are in a process of elimination at this stage testing different armatures to see what happens and our results were better than I expected.

Take a close look at the FEMM drawing,there are a lot of clues in it. The red coils are the input and the green is the output. if the other two white coils are used' the 3 o'clock is powered and the six o'clock is an output. If you don't split the case you will only be able to use 2 stator coils and it will not perform as well. the black boxes represent the location of the carbon brushes.

With my design we have transformer and generator action in our output coils but I have not seen a scope trace yet.

PWM circuit

This is the PWM circuit I used.

Pulse Width Modulation - Electronics in Meccano

Instead of the TIP31C, I used a TIP122.

I replaced the M (motor) with a 12V relay.

The relay contacts switched 24VDC into the universal motor (unmodified and modified).

Given that there are 400++V spikes being generated (at 12VDC, 24VDC and 36VDC pulses), it might be a while before I find something solid state to replace the relay...

unmodified motor

The motor I'm using is a 2-pole universal (probably from a hand drill).

Here's a scope shot of the 400VDC spikes being generated in the motor before I modified the motor. The motor was being pulsed as above.

The 2nd pic is that of the sparks inside the relay.

Hi paul,

I have tried switching with a relay in the past because I like the abrupt switch but unfortunately it is difficult to get the frequency and they do not last long. When we get around to commutative switching as in the original lockridge it will be a lot better.

There is no reason why this cannot be done with modern electronics instead of a commutator but I expect we will have some issues burning semi conductors out on the way.

At the moment, I am fairly sure of the motor coil and generator coil configuration, I am fairly sure of the armature too but we have to eliminate all other possibilities just in case something comes up with other configurations. As it is, something has come up with a lap wound armature and we are testing it. There are a few possibilities for the recovery circuit and a few for the trifilar coil and capacitor but we are narrowing it down.

The thing is it wont work without all the parts being tuned. If someone has a perfect motor generator but the trifilar isn't right it still wont work. If the device was 100% efficient the COP would be greater than 8 but we know that the universal motor part is around 35% efficient and there are other losses too such as a cap being 50% efficient. Overall I am expecting around 130% or less when we have everything configured. I figure it will be running at about 800 to 1.2kw with an output of around 250 to 300w and it wont run for many hours without needing new brushes.

No this isn't going to be the ultimate device but I believe if we can get it working it will win the minds of science.

HI mbrownn.

If you get a working OU device what are your plans?
Will you open source it, produce it and sell it?

I know it is too early to think about it.
I just want to know your ideas.

[mbrownn]

All three, I have come to the conclusion that the only way to get this info out is to do that. put it out there.

Hopefully I will be able to make a little on it but if not, I don't care. Hopefully I might even get some credit too but that isn't what matters. Don't get me wrong I could use the money but as long as I have a roof over my head and can feed my family that is all that matters.

Hi guys.

I'm working on a new motor design which is why I have'nt posted lately.

I just donated $25 to help Eric Dollard.

This is one guy who gave his life to advance free energy via Tesla's teachings.

If any of you can help, please do.
Thanks

Hi guys,

Matthew Jones is going to help me with this but I wanted to ask also--I put together this zig zag wound regenerative motor with the MY1016 scooter motor and 18 AWG windings. It goes a partial turn or one turn then it reverses itself and stops. My guess is that the magnet field from the windings are clashing with the permanent magnets when the rotor turns 1/2 way. But I'm not sure what to do about it or what's causing it. I know my winding is probably not great but is this the problem? Wondering if anyone can help. Here are some photos, thanks!

Hi Mike

I'm surprised that the windings are not done to form poles - that could be the way it's meant to be, plus the seem commutators offset. Do you have a winding diagram you can post up?

Hi John,

Well I wound it like Peter Lindemann says earlier in this thread only I spaced the second set of commutator brushes slightly less than 1 commutator segment as per a suggestion that he said would be okay. I've never wound a motor before but it does spin a bit with torque, the problem I'm having is that it just blocks itself when it goes around a half turn, it seems when the commutator segments with the wire ends touch the power on the half turn:

"Starting at the commutator side, lay your wire into slot #1. Coming out of Slot #1, lay the wire along the back edge of the rotor until you get to slot #5. Then enter slot #5 and come back to the commutator side again. Then go over to slot #9 and lay the wire down slot #9 and come out on the back side again. Then go over to slot #13 and come back over to the commutator side. Then, on to slot #1 again.... around in that pattern until the slots are filled. This is for a 16 slot rotor. The ends of the wires will terminate on two commutator segments that are 180* away from each other when the wire in the slots are sitting in the middle of the stator poles.Hopefully, you and everyone else can understand this. The commutator section is just arriving at the brush when the windings are in the middle of the magnetic fields. The windings on the back side of the rotor cross from #1 to #5 and from #9 to #13, assuming a 16 slot rotor.

I hope this clears this up, once and for all.

Peter"





Thanks!

Need Diodes on the rotor

Blargus,

Please go back and look at Matthew's modifications for this motor. He ran into this situation as well, and solved it with some diodes in the rotor windings, I think.

Before his ideas were hi-jacked by one of the other people in the thread (name withheld) there was a lot of excitement about this project, and his initial tests were showing significant benefits.

I'm glad to see you picking this up again.

Peter

[Blargus]

Ah thanks a lot Peter/Dr. Lindemann! I tried external diodes but not that! I really liked your lecture and also when you shared your permanent magnet DC arrangement . Thanks so much! A lot of the links from that person that would not listen to you guys seem to be dead...maybe "high winds do not last all day." I'll keep at it!

Thanks again,

Mike Swanson

Update: It runs now and I am getting recovery @ 12V. And we're off!

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.

Robert

Thanks Robert,

I know this is an old post but thanks,

I think the Lockridge device did have an external switching device or a relay to control the charging or discharge of the large capacitor involved in the circuit. Robert49 friend stated he heard a "clicking" sound from the machine.

Not sure, just bring up a possibility.

I'm still trying to replicate this device with a 1950's generator that:
1. the slots are cut down the sides of stator
2. the rotor is stripped and waiting new windings
3. commutators and brushes in hand

Now testing trifilar coils and like the results so far.

Questions to all,

1. Was the capacitor wrapped around the coil or was it separate?
2. Was there four brushes filled down really flat to just touch one segment at a time?
3. Is J. Bedini going to make any more videos on this machine?

Yes, I've watched/studied all the vids and books and such. Just need a little help here and there.

Thanks,

Hi, wondered if anyone had thoughts about my zig zag rewound scooter motor. I've been looking at the running and recovery, the recovery looks like this:

at 19V:


Coming from the run batteries looks like this:




Wondering why there appears to be a radiant spike but going into run battery, not recovery battery. My brushes are spaced a little less than 1 commutator segment and the diodes I am using are in motor NTE 598 600V 8A ultra fast and on recovery batteries UF 804 same specs I think. I have recovery side diode on a clip lead going to recovery battery positive. Highest I can go right now is about 34V, still notice the spike there, maybe if I go faster, things will change?

Anyway thanks, I'm not too picky right now I'm just glad it runs well!

@Blargus On recovery

The interactions between the armature and the field magnets are very complex, there is a lot more going on than you think, especially if you use field coils. I am working on this currently.

Hiwater has had some very interesting results using field coils where we get a multiplication of the voltage that we think is caused by a transformer action and a changing inductance in the armature winding. The armature used was lap wound.

I believe that the armature should be wave wound in a fashion similar to Peters.

@wantomake

The trifilar coil is likely to be used as some sort of choke to supply the motor. The reason it is wrapped around the motor is to pre saturate the motor core before the pulse, this way we have less core losses from the other functions of transformer and motoring. It also has other functions but I have not got them all worked out yet.

I believe the capacitor was wrapped around the coil but Peter will know better.

Filing the brushes down to one segment width does seem to be a requirement.

In my opinion, to really make this work you need to start with a four pole motor with four field coils, this is how the unit JB appears to be.

The motor is not wired in a conventional fashion but appears normal, this is to reduce BEMF. In truth there is no motoring action from the motor field coils thus no BEMF . The motoring action comes from the generating coils There is acceleration under load due to transformer actions All the BEMF is in the generator coils, this BEMF is the generated current. There is a very complex transformer action between the motor coils, armature coils and generator. this transformer action can be made to add to the generated voltage.

Please ask me some questions about this
