    The curiosity has been overwhelming, regarding has anyone in this world to this date, finally design a functioning machine that actually mimics what that German Engineer put together and Sgt Lockridge found? Forget what Lindemann/Bedini attempted to "think" what it does, but look at those old pictures and then you'd conclude this is not a 230VAC machine. The Armature of a 6VDC Bosch Generator can only produce up to 10+VDC. You have to go back in time and understand what those materials were at the time. Those metals making up the Armature, the Stator, the Mag Wire, all those materials we take for granted in 2021. But not available in the 1940's. Who has done this?

    sad. really. But a wife is usually no inventor.
    maybe i face same faith in the future when I follow my research ...

    how many turns you do on 1 winding on your armature ?
    It was a long time ago when I wound that armature, I think it was 30. It ran on 3 to 4 volts at 4 amps. 4 amps was the limit on my variac. On a more recent armature there was only 2 turns per winding and 6 turns on the powered field winding. Obviously the current was huge and too big for my meters. This was based on a yanmar starter motor. I am no longer in possession of these devices so I cant give you any new pictures.

    If I understand you, yes. From one segment, round 90 degrees to the first slot on the armature. Then wind a turn around the left side of the shaft to the slot 180 degrees from the first, the next turn is around the right side of the shaft and so on until the slot is full. Then pas the wire to the commutator segment opposite the first

    cheers
    Correct, The small armature was my first attempt and like an idiot I did not realise that leaving only one segment blank would give no off time. This worked out well for the MADMAG but did not give as strong transformer actions as I wanted. So to simulate this I fed the motor with Half wave rectified AC and got interesting results. Later I replaced the carbon brushes with spring steel (actually razor blades). The next motor was a starter motor and I was working on getting the sweep angle correct when all my equipment was taken (no conspiracy. I got a divorce). At this point with no equipment, I decided to try and get people interested in my work so the development could continue.That was about 3 years ago. I will be ready to start building again in the next few months.

    When I buy the Bosch generator I my first thought was, **** how this dirty thing works. real Hard (!) ware

    I have fear to destruct my armature if I begin to unsolder the windings.
    But wire to wire it should work

    The hardest part is getting the old windings out as they are usually held in with epoxy. I used a hack saw to cut the windings off at each end and then a punch to knock them out.
    This video will help you with the wind, the only difference is I connected to commutator segments at 90 degrees do that i did not have to move the brush holders that were already there. http://www.energeticforum.com/redire...lpage%23t%3D99

    1,

    I realize at the "interesting motor" that you solder not every plate
    on the armature with a coil because you will reduce the "brushfire" by
    switching to the next segment. OK

    so i think I can place gluefilm (isolationtape) on every 2nd plate(segment)
    of the armature right ?
    With that motor we are avoiding transformer actions so every segment would be fine, remember this came as a result of my research so I left options to make it what we are talking about now. I would recommend you start with only one coil on the armature, this makes it much easier for setting up the motoring function. After we have the motoring function set up and tested, we can add extra coils.

    What I am thinking right now is 4 blank segments between each coil. this will allow a full charge and discharge of the armature before the next coil is charged, but this may change, as I'm still working on it.

    to set the wire lap in a 90 degree formation. OK
    a lot of work for me to rebuild the commutator. OK this work have to be done.
    The 90 degree setup on the armature is for two reasons

    1) so that the commutator will line up with existing brush positions
    2) It keeps the wires close to the shaft preventing them getting caught in the brushes.

    Nothing special, just practical.

    I donīt think you have the time, coz soon you are lost contact you will get the kickback and this kickback can fly to the brushes if there are in the air.

    so the only logic is to put the 2nd brushes to the same segment, before
    the 1st brushes leave it ! True ??
    Exactly. The contact is made slightly before the other brush disengages. I did this while the armature was running, slowly moving it until the arcing reduced.

    The way I set up the MADMAG, the overlap can be greater.

    Going back to the commutator, I had one blank between each coil, this was great for the MADMAG, but didn’t seem so good to get the transformer actions like we want in this device. In the MADMAG it gives us one coil charging and one coil discharging at the same time, there is no off time to speak of.

    For this device, by having brushes the same width as the commutator segments and 4 blank segments between each coil, we will have a 50% on time and 50% off. This requirement makes an ideal armature to have an even number of slots, the commutator ideally would have double the number of segments as there is slots, and that number be divisible by 5 ie 10, 20, 30 etc. This isn’t proven yet, but is what I am working on now.

    For my MADMAG (interesting Motor) we may be able to use off the shelf field coils and get reasonable performance. For the self runner, if it is possible and I believe it is, we will need all the parts to be matched to get optimum performance, but what those specifications are remains to be seen.

    If one of the functions of the trifilar coil is impedance matching, this may help us, but I don’t think it is going to be that easy.

    You take the generated current trough the motor windings to compensate

    When we draw current from the generator, it causes drag, the motor slows and the BEMF in the armature reduces. This allows more current to flow. Also when a load is placed on the secondary of a transformer, the impedance drops and more current can flow. Normally all the extra current comes from the source, but as we are creating current in the generator it makes sense to use that too.

    The voltage drop across the motor is very small, so if we make the voltage of our output higher than the motor, it will draw generator current through the motor with little voltage drop. We can still power our load but the current flow has assisted the motor. This extra current in the armature causes more generated current so it is a self compensating loop.

    As the transformer action is lowering impedance, more current flows, which in turn causes stronger generation due to the higher magnetic fields in the armature. Again it is self compensating the the generator.

    Increasing the number of turns on the generator will give us a higher voltage but lower current, as the voltage drop across the motor is the same the compensation will be less, as the current is less. Its another compromise. I don’t know what the ideal voltage would be from the generator, we will just have to try it out.

    Not exactly, we can drop the impedance with the transformer action, We want very low ohmic resistance both in the field coils and the armature. Big wire. This is why I play around with starter motors as their ohmic resistance is often below 1/10th of an ohm. The problem here is I may be too low on the inductance, another compromise.

    Your asking the right questions

    #13 efficience 2:
    In effect we are using our electrical draw from the generator to compensate for the increased load on the motor by passing its current through the motor windings first. Yes, the motor will slow but by not as much as expected. The lower the voltage requirement of our electrical load the more current drawn and the greater the compensation.

    Yes I knew that Iīm wrong because the image makes no sense to me.
    ( I hoped you would draw a correction over my Image to see clear)
    I read the post "interesting motor" yesterday but I have to read it again
    No problem, its so obvious to me because I know how it works, but I forget that no one else has seen anything like this I will go through it again with this drawing http://www.energeticforum.com/attach...-coilsetup-jpg

    This drawing is like someone cut the motor in half so you can see the exposed parts. The red coils are powered, Imagine the current flows into the screen at the top red parts, and flows out of the screen at the two bottom red parts. Pretend that the coils marked in white are not there nor are the shoes, so we are only looking at the top left half.

    from this you can see that the red coils will be in attraction. The motor would not rotate if it were not for the shoe placed at the 12 o'clock position. This shoe gives a return path for the flux, but as it does so, it pulls on the top part of the armature coil making it rotate anticlockwise.

    So as a new armature coil comes in from the right, It switches on at the 1 o'clock position, it rotates anticlockwise to the 11 o'clock position due to the flux pulling the top half of the coil. As new coils come past the one o'clock position they switch on and switch off at the 11 o'clock position. At no time are any of the other armature coils on.

    If you can imagine this rotation you can see that no powered armature coils sweep past the coil at the 9 o'clock position, this is why there is no significant BEMF generated there.

    In truth the armature coils switch off just after passing the 12 o'clock position. It is the recovery brushes that make contact with the armature coil at this point, and the inductive kickback then powers the armature towards the 11 o'clock position, but you can ignore this paragraph if it confuses you.

    As the armature has current passing through it while it is powered, it makes sense to place a coil at the 12 o'clock position and let it generate. This is what the two dark green parts are. Because we have current flowing in the generator coil, BEMF is generated in the armature coil. We haven’t totally eliminated BEMF, because we have some BEMF in the armature.

    Effectively we now have a low BEMF motor, and generator combined.

    You may find the next few paragraphs confusing, If you do, ignore it for now, but it is the part that we will exploit in the lockridge device. The previous part is the "interesting motor"

    As the commutator switches on and off coils, the armature is pulsing. This causes a transformer action between the armature and generator coil because they are on the same magnetic circuit. This is what gives us our AC component in the generator coil. The same will happen in the powered field coil.

    As the AC works with and against the DC it effectively self cancels. we cannot use the AC as the system is. The effect of this on a well set up device is that the AC transformer action lowers the impedance of both the powered field coil, the armature allowing more DC to flow.

    This effect is even more pronounced if we make the powered field coil pulse with the armature, by wiring them in series. By leaving out coils on the armature, or by using blank segments in the armature we can cause the current to actually stop in the armature for an instant. This intensifies the transformer action and the effect on the impedance.

    This lowering of impedance and increase in current actually cause the motor to accelerate when the load is placed on the generator Im not joking. Yes it is drawing more power but it is generating more power too.

    Imagine what could happen if the motor speed caused the pulsing to reach the resonant frequency of the coils!!!

    This is a lot to take in in one post, sorry for that.

    Congratulations, you have thought of another of the methods of spiting the AC from the DC, but I never figured out how to get the DC out, and so have never mentioned it on the forums. Its one of the many things I call "a work in progress"

    I think we are going to make some progress

    Correct, hopefully you can now see why.

    I suggest you build the "Interesting Motor", I call it the Motor Assisted Generator (MAG) or Motor assisted Dynamo (MAD) Then run some tests on the pulsing so we can narrow down the options for splitting the AC and DC

    Sorry for the long and in depth post

    It is how the device is made to motor that is different. Little or no BEMF is generated in the field coils because no armature coil passes them while it is energized.

    Sorry, no that’s not correct. Try reading this thread and see if you understand better http://www.energeticforum.com/renewa...ing-motor.html I talk about the construction from the 7th post

    If the generated DC is 12v the AC will vary this DC between 24 and 0 v. Effectively the AC gain is lost when the voltage drops to zero.

    There is another way around this problem using reactance (I think thats the correct term) ie the voltage may drop to zero but current still flows. Its something I am trying to figure out.

    The generator is absolutely standard and so works in a conventional way.

    It is how the device is made to motor that is different. Little or no BEMF is generated in the field coils because no armature coil passes them while it is energized.
