Lockridge Device - Peter Lindemann

[Hiwater]

This sounds like what is happening in the three battery generating system. The
increase in RPM's when the load is added. Somehow the same principle is at work here. The drawing in of more radiant energy or something. The original
Lockridge device used a 300 watt load, either a light bulb or small 300 watt
heater. This load is an important component of the overall system. Sounds like
all that is needed in your setup now is the right capacitor with the correct connections and you have the Lockridge device solved.

The negative brush has to be on a certain commutator bar for that to happen. Other places it wont work just slows down the motor. From what ive found the load has to be an inductive load for it to work better. Lots to work out yet.

Shorting commutator to case

Mbrownn, I did manage to get time to slot the generator case on the brush end of the case , so the brushes can be moved 180 degrees if needed. there is a spot where the dc and voltage picks up. Dc 20 volts - ac 40 volts off that one only on commutator section, thats is where the voltage is the highest on the pos side of the armature. The negative side drops down to 8-10 volts. that is the 5th comm segment from the pos brush going against rotation. The other sections lower the voltage.

I did connect a 12 volt heater fan to that section and it picks up and spins like a normal fan would connecting across a battery.

When i was checking with the volt meter to find the highest voltage spot a I grounded the comm bar out to the case and the motor picked up in rpms. I checked this quite a few times the rpm gain was 722-873 rpms. So i connected a 12 volt heater motor fan to the brush i had added to see what would happen. the heater motor picked up and run like normal, but was strange was that the starter generator picked up in speed too. never checked rpm gain at that time though.

Going to do some checking today to see whats is going on. Now if i put a 12 volt bulb on the generator coil it just about stops the starter generator.
But when i put it on the comm section it gets bright white and rpm picks up. There is absolutely 20v-dc---40v ac. Some times up ti 48 volts ac. I rechecked this many times.

starter-generators

What I have done in the past is to take a starter coil from an older 6-12 volt and put in the stock Gm generator. This does about the same as the starter generator combination. These will also motorise with just one motor coil . No other coils connected by putting the motor coil under the negative brush. One wire to the power in put and the other wire to the positive brush. the negative is grounde to the case. depending which way you want it to turn.

Ther is enough room to put other brushes in the case if you have some extra ground brush holders or modify the pos brush holder. the pos holders are to long and have to be shortend to get on the right comm section you need.

These starter generators will spin up to any where from 4000-6500 rpms depending what size starter feild coil and feild pole you put in them.

What did you mean for sure about the ratio, was that the number of turns for each coil.

[Hiwater]

Thanks guys for the info, lets just say these generators are not here in SE Asia. yes they do look like they are good candidates.

I would be interested to know the ratio between the motor coils and the generator coils

Mbrown, I have at leat five of these iv been working with. The motor coil is quite good size about 4 inches wide andabout 5.5 inches tall. The feild charge coil may be larger too. The motor coil uses flat normal starter windingflat copper. The feildcoil is larger in the sense it isnt as compact as the stock GM generator, more spread out along the edge of the feild poles. The armature is basically the same same number of bars and slots. The winding on the armature is a little heavier than normal generators. They also hav thick brushes made out of copper. Brushes are at least one quarter of an inch thick. Dont know the ratio of winds from one to another.

There are no separate motor coils and generator coils. The armature is wound with heavier wire than would be used for a regular generator. Full voltage is applied to the field coils and the armature to start the engine and it turns the engine using the heavy v-belt that is also used to turn the generator when the engine is running. When the engine is running a regular mechanical voltage regulator is used to control the current going to the field coils which controls how much voltage is generated by the armature coils. Since this is used as a generator maybe the armature coils are already wound the way you want them to be. I worked on a lot of these when I used to work on lawn and garden and farm machinery, but I don't remember how the armature was wound. Maybe with some research we could find out. I wish I had thought of this several months ago. It may have saved some time and effort looking for a suitable device to convert.

Thanks Cifta

For you guys that think it would be easier to convert an old generator there are plenty of them on ebay. Another idea might be to convert one that is already a starter generator. The old Cub Cadet lawn and garden tractors used a combination starter generator. It was used to start the tractor and then used to charge the battery. I see on ebay where Yamaha is also using something like that on their golf carts. Some of them are as cheap as $40 for a good used one.

The starter generator does sound like a good idea.

Here is 1950's Delco Remy 6v generator from a John Deere. The guy is trying to
convert it to 12 volt. Look at the picture of the coils.

No, not yet but I plan to include other motor configurations in future, although I cannot say how soon that will be. I will be happy to assist where possible.

I guess that the most important parameters will be the field coil and armature inductance and resistance values, as well as the geometry of the motor. If cores are involved I will need to know which materials and dimensions in order to estimate the nonlinear inductance relationships that can be expected to play a big role during high current surges. However, I will first need to study all aspects thoroughly before I can say for sure.

I prefer running mathematical models prior to starting experiments just to see what conventional theory has to say (conventional theory as used to model specific phenomena - not general laws that are only applicable under certain assumptions). That way I can study the relationships between parameters and see which combinations can be expected to work the best. Also, if the model says it should work and it does not work in practice, it provides more motivation to try again - until you can reconcile the two. That way you are always sure to learn something - even if it is where you made a mistake in your model or where the model needs to be expanded. Like they say, six months in the laboratory can safe you a day in the library. However, I am all for experimental studies in fields such as this one where the library does not contain a lot of applicable information - not yet.

I have a goal of fully understanding higher-dimensional electrodynamics, such as Sachs O(3) electrodynamics, which according to Bearden does take vacuum interactions into account. Once I have enough knowledge of that theory I hope to model it and use that to analyse various devices that claim anomalous behaviour.

On a different note, I am having difficulty getting data on starter motors - specifically the inductance and resistance of the field and armature coils and the speed and torque constants. I will appreciate any datasheets / resources on this as I expect them to have a large torque constant.

When I have my motor wound I will give you the info that I have for it but for now I can give you this..

Rotor diameter 31.7
Rotor length 30

Rotor coil dimensions
coil width at the core 18
coil length 30
wire #22 approximately 60 turns (we will get a real figure when I wind it)
6 coils fitted but only 1 energized at a time with 1 on recovery

Stator internal diameter 32.5
Stator length 29.4

Stator coil dimensions
length 29.4
width 19.7
Number of turns will be the same as the rotor as will the wire gauge.
Only one coil used for the motor.

Rotor and stator are laminated with standard materials for this application

There is nothing wrong with mathematical models if we have all the parameters for it, unfortunately the electrical theory is incomplete so that puts us at a disadvantage. You may be the only person in the world that is looking at this mathematically, think about it, your work could be very important. This is why I do not dismiss anyone with ideas.

The only starter motor information I found was a Ford Fiesta starter 200uH and 0.046 ohms

[mbrownn]

My view is, if we want to construct a real Lockridge device, we must use either
a VW generator, 6v or 12v or the 1950's Delco/Remy generator and get them to function as a motor at the same time that they are generating. Most of us went
at it backwards, trying to start with a DC motor and have it generate at the same time, with or without modifications. Had generators been used, earlier on
observation of how they operated would probably have led to the correct modifications being done to get this to work. Only after a successful replication
is done with a generator can we then try to modify a motor. I might be wrong,
but this would seem to be the easier path to take.

George

Yes you are right, if we all started with delco remy generators we would have probably got here quicker purely by trial and error, but would we understand it. If we could replicate but not understand it we would be like lockridge ourselves and would not be able to develop it further.

These generators are not readily available so we are left with motors to work with.

Motors are not built to be as efficient so this is a problem but we will overcome. I think we are 80% there and if you do have a delco remy generator contact me and I will go through the modifications with you.

It is interesting to see someone look at it from a mathematical point if view. I can't say I understand it but I am sure that others may find it of interest. In a few weeks when I start testing maybe you could do some calculations to assist us understanding what is going on.

Could your spread sheet calculate expected efficiencies for a universal motor and what information would you need to do that?

No, not yet but I plan to include other motor configurations in future, although I cannot say how soon that will be. I will be happy to assist where possible.
