  Done the tests per your diagram with the coils and brushes at 180 degrees apart. The motor coil under the pos brush and the gen coil under the neg brush. No rotation. starting to figure this armature ous some it operates in quadratures. never realised that untill today working with your diagram. If both coils are on tdc it wont rotate.It may go either way like you said. that was a BIG clue for me. As I started working with the coils that started to fall into place as I moved the gen coil towards the motor coil. I could see how it works in 1/4s. Because when i got the gen coil at the center of 1/2 of the srmature it wouldnt rotate. Untill i went past that 90 degree point then it rotated the other way. The 90 degree point is the highest point of magnetic feild which is one-half no and south. So it wont move untill there is more of one than the other. depending on which way you move the gen coil. So the gen cois has to be off center one way or the other. ( this was a good learning experience for me todayit put a lot of things together that i can try to figure out now)
    As per your diagram if i move the gen coil towards the motor coil in the direction against rotation 45 degrees seem to be the best spot. When first spinning it up 3300-3600 rpms the input volts were 10.5 and the output volts were 46.2 volts Input amps were 29.86. out put amps to heater motor was about 1.97-2.01. VOLTage drops down to about half. The moving of the gen coil is figured as cw rotation. Putting it under load it slows the motor way down.
   The only times i have had some acceleration under load was when the motor coil was beyond the pos brush against rotation and the motor coil closer to the pos brush against rotation. now that i realised about these quadrants hope fully i can place them better now that i know this. That was a lot of help so a BIG THANK YOU FOR MAKING ME THINK. Dont know for sure how much ill get done tomorrow, other things on the agenda.

 You asked about the accelaretion under load. When i slowed down the heater motor the gen slowed way down and the input amps went way up spiked at almost 39 amps before the breaker clicked off. When i get the coils in the right place it does accelarate under load. Not a whole lot but it is noticeable. The ones i worked on last winter would gain close to a 1000 rpms . that was with one starter motor coil for running and one regular delco generator coil fot the generation side. Increasing the air gap also helps that effect also, but it might hinder us here on the t-effect. thse delco feild colis take up 1/2 of the armature so that might of helped it too. Also when i got to a certain rpm the bemf didnt bother too much either. that feild coil was run inseries off the positive brush and then to a bank of 12 volt light bulbs. I had 6 or 7 bulbs connected up in which i could flip a switch for each bulb. each bulb i put on would increase the motor rpm all the way up close to a 1000 rpms. i had one set wound inseries and another set for parallel use. cant remember which was the best set though.


Thanks again for all your help . i have learned a lot through all these experiments. hope fully we can get these coils positioned in the best place now and see a good acceleration under load.

If the armature is set up in quadrants it may give us anomalous results and you wont be able to do the tests that I now need. The only way to find out is to run a current through the commutator at opposite segments and check how many poles there are with a magnet. A normal armature will have two, one in attraction and one repelling, if it has four I will have to try and see how to work with that.

I'm not totally sure I understand your posts so I will spell it out how I would like the tests done. Take a look at the picture I have attached, I am assuming you have two field coils and the other field coils have been removed.

The red coil is powered at the same time as the armature, the green coil is the output. The white coils and shoes have been removed. The brushes are marked in black. Is this how you have it?

I think it must be something like that otherwise I would not expect to get the results you have.

This is a conversation I have had with another researcher who wishes to remain anonymous

When we put a cap in the return line we can collect energy that has passed through the motor and is not consumed by it. If the motor consumed all the energy in its losses and power output, there would be no energy to be collected here but we can collect energy here. We know if there was no potential there would be no current flow, yet current flows. Matt has collected energy from this using transformers, in fact it could well be a principal involved in his Tesla switch without him even knowing it. I wont say this to Matt as he attacked me for saying motors have a transformer action, according to Matt "there is no transformer action in a motor, Period". I disagree but let him have his way. On other topics Matt is excellent so I am not knocking him. Think of it as water that has passed over a water wheel, it is still moving and has energy.

No, not how we build motors today, we need the armature in place as the flux passes through it. Ill attach a FEA of a universal motor, imagine the top coil is powered and the bottom is the output coil. Effectively this is like a standard transformer except that the windings are not wound over each other. The armature coil, if in series would make it a 2 to 1 step down and if in parallel it would be 1 to 1 but with higher current assuming all the coils have the same number of turns.

No, not exactly, for transformer actions you need a change in intensity of the flux in the coils, no cutting necessary. Generating requires movement of flux laterally (usually referred to as cutting). Both these are changes in flux but are distinct and if both occur in the same coil they are additive. What I am about to say, keep to yourself for now as I am not sure about it, It is this, that is a possible gain in the SSG. I say I am not sure as the switching occurs after the magnet passes the coil.

So why do we not see the gain when using the second coil as an output on a universal motor? We do get the transformer action and we do get the generator action in the second coil just as I explained but the generated action in the primary opposes the supplied voltage so that the effective voltage in the primary coil is dramatically reduced. Typically over 90% in an unloaded motor and 50% in a fully loaded motor. This will mean that the gain from the transformer action is between zero and 50% and if our motor is less than 50% efficient the losses will account for more than the gain and so the motor remains below 100% efficient using the compensation as an output. For this reason we have to stop the BEMf in the power coil and to do this we have to move it away from the moving flux in the pole.

If you think about this you can build a much more efficient universal motor, so how do you do it? If you don't figure this out in your reply, I will tell you but I want you to start to understand what we are doing and why it works.

Excellent, you are already starting to think.

I believe our armature only requires two poles.

The action of the transformer effect is independent of the motor until BEMF kills it. Inductive kickback adds to it, as it also adds current flow. The transient is momentary and has little effect on motoring but we will also collect this in the lockridge. When we power the pulse the current ramps up, we switch off the pulse and if there is a conductive path, the inductive kickback will ramp down current adding to the overall current flowing in the motor. Remember it is current times the number of turns to get magnetic force, voltage is irrelevant. Volts times amps in a transformer provided the flux is changing intensity. Half our transformer action comes from the inductive kickback and so we did not have to pay for it.  Not sure I explained it well, ask me about it if you don't get it.

The whole motor is the transformer. but we will deal with the armature's specific role later, I need you to get this transformer action. To do it with a PM DC motor you would need a special armature

You are correct with an off the shelf motor the way we wire them but it is possible to wire a 4 pole motor so that BEMF is dramatically reduced. Remember BEMF is generated current, is the same thing, its just what coil it is in that determines what we call it. Generated current, BEMF and the output of a transformer all occur in the opposite direction to applied current in a motor.

Im not sure what this is but if it is what I think it is the answer is yes but we have to try and minimize this.

   I apologise for not getting back to you in  timely manner. Had lots of things going on in the family. Plus we got dumped with snow last nigh. So have

   take care of that today. i did read your lasts posts very interesting. Bemf is the same generated current . Very good. So now we know we have some

   power in this. what we need is the coil positioning  of the motor and generating coils to pick this up. Be back this evening to answer your above
   
   questions.

    The armature is 1/2 north and 1/2 south. Between each side at the half way point is the highest magnetisim on each side. moving from there forwards or backwards changes rotation direction. Also changes voltage output. So no you are ok with configuring this armature.
     
     Your attached drawing in post 226.  I had everything right except i had the gen goil on the opposite side. This afternoon I changed it to the other side at 90 degrees. This made quite a lot of difference in the  running of the motor action. It seemed like the motor run more free. but the input amps wre still at 29.0. output voltage49.5 volts. Which was a little higher for that side of the armature. Motor did slow up on load.
    Motor coil no load 8v input    amps 21.94   out put volts 44.2
    motor coil under load. 8 volts input  31.49 amps.    Heatermotor as load draws 1.30 amps. volts drop down to .6 from 27.9 volts.
   
    If there any more questions dont be afraid to ask.

Just doing the maths on your input and output figures suggests we need over 50% recovery in our recovery circuit, a bit of a tall order but for now continue testing. Another researcher "Pault" has let me know some information that may reduce drag and believe it or not, it is the trifilar coil. Its like all the parts are starting to come together.


[/quote
  Sound like this man has done his homework. How does this do this. Must be receiving the kickback from the armature. We can think of it as the motor going clockwise and the generator counter clockwise in the same case. Two whilrwinds at the same time. if the kickback is a different polarity will the one motor coil have to be wound opposite. Maybe not if its on the other side of the armature and timed right it should move the armature ahead. Dont let this quy out of your sight sounds like he invaluable.        FORGOT TO MENTION THE THE RPM IN MY LAST POST  on the tests i did with the gen coli on the other side. they were 4194, which I thought were pretty good.

Ok that is good.

I think you should try it with a lower resistance load so that it draws more amps, you could even try feeding the output back to the input and see how much the input draw drops

Maybe now we need to slot the case and power the other side and tune to optimum input power to output ratio. After that we need to pulse the motor which will require making a simple commutator placed on the output shaft

  I havent abanded the work on this project. I have been working on the m1 and g1 coils before I do any more tests. Have replaced the motor coil with a taller one with a longer pole shoe and also put in a wider pole shoe for the g1 coil.

  The wider pole shoe for the gen coil may prove not useful. it covers 3 armature slots instead of just 2. Plan fot today is to work with repositioning those coils th get the motor to accelerate under load.

  i can clearly see now how this armature reaction is supposed to work when moving the coils. (light finally come on) as to what is happening when the coils are repositioned. Now that i have a better understanding of what that purpose was for. I can think this through as to what is happening with each coil and the armature when moving them in the case.

  So we are still moving forward, just another part that has to be solved.

Good work my friend, this is very significant. I have been trying to stir up some interest but with little success, I guess people will only look at it once we have a complete device but what we are doing is research. The reason I am sure this is the real thing is its complexity, it combines many methods of getting gains all in one device. What you are doing now is reducing the BEMF, hence the high current draw, and tuning the generation. Normally with such a high current draw we would have a very high mechanical power but in our case we do not see that. This is because we are generating at the same time which is absorbing the mechanical energy. I remember you said that the motor growled and hummed, I expected that, this tells us that we have huge magnetic forces taking place in the system. Keeping the motor coil in the perfect magnetic lock position and moving the generator coil to obtain maximum power out of the output coil is the goal.

Try using a bank of 12v 100w bulbs  in series or parallel as as load, add or remove bulbs until we get the maximum power coming out of the coil then we can compare that with the input power. If we get above 50% efficiency I will be very excited as at this level a self runner is definitely possible, it may be possible at lower efficiencies because of the effect of all the other parts but we will have to see.

Do you have access to a lathe?

It is only a test and as we do not have a method to pulse the motor at the moment, it is the nearest we have to pulsed DC. The voltage needs to vary so that the transformer action takes place but we do not want to use AC as the voltage reverses and inductive kickback cannot be collected. There will be no benefit from inductive kickback using this supply but there will be when we do pulse it.
Ok. thanks.

I think half sine wave do not replace pulsed dc. there is no sudden voltage termination in half sine wave.

I am confuse, do you detect inductive kick back from a transformer running with half wave sine wave?

Exactly, we can get a transformer action but no inductive kickback with half wave rectified AC.

Once we switch to true square waves we should get inductive kickback and if we get the duration of the pulse short enough we will get a relatively large percentage of our pulse back. This is our first gain in the motor as up to half of the current could be supplied by the inductive kickback, thus up to half of the transformer current and up to half of the motive force could be supplied by inductive kickback. In my previous tests I was able to get about 17% extra motive force and recovery by this method, if it proves to be the case that the same amount of transformer current can be obtained then we have 34% extra energy in the motor. This will raise a typical 35% efficient motor up to a 69% efficient motor generator.

Now if we recycle that 17% by collecting it in a capacitor as well and feed it back to the source we reduce the input by 17%. Now we are on a 86% efficient motor. This is the recycling

My tests before were on a modified induction motor (the Lindemann rotary attraction motor) the pulse duration was far too long and so the recovery and gain was low.

Our first tests on this motor have been 37% efficient with the half wave AC and we can improve that by closing the gap between the rotor and field poles (currently about 1.4mm and 0.7 to 0.8 being the optimum) so I am anticipating slightly better results. At the moment we are working on improving the efficiency of our basic motor, If we can get it above 50% efficiency then overunity or selfrunning is possible. Motors of 70%+ efficiency have a gap of 0.7 to 0.8mm. With smaller gaps the transformer coupling will improve too.

   Yes there is a huge magnetic lock. Didnt try turn it by hand but I could tell from the way it sounded. When it did this it buzzed so much the whole generator would move around because of the vibration. before it done this it was like the gen case would try and twist just a little to line up with the flux on the armature. it was so strong you could almost feel the struggle inside the case.

   I have been so accustomed to working on these generators and running them as motors, that I failed to recognise that i was running them where the gen coil should be. Because what we are doing is to put the motor coil in a position for a dc motor and the gen coil in position for generating.

 Once i get the coils in position. i will try the 12v bulbs, to see how it acts. Some of the things Im doing now is proving to my self how this armature and feild coils interact. Really interesting how this flux changes on the feild poles. Another thing I didnt know is that there is a portion of the armature that is used for demagnetising, still trying to learn more how this effects the feild poles. Maybe you know. I dont fully understand it yet.

I think we need to standardize our terminology so that we do not misunderstand each other as your second paragraph could be interpreted two ways. We could use a clock face as the reference, 12 o'clock being where the positive brush is and 6 o'clock being where the negative brush is. So at 12 o'clock we have the motor power coil and at 3 o'clock we have the generator coil, the other coils and shoes are removed. If you have slotted the case the other coils and shoes should be on the other side of the slots.

Using the above as a reference, at what positions would the motor coils normally be as a standard unit? I would assume that they would be at 9 o'clock and 3 o'clock

Have you slotted the case yet? There is no need to slot the case yet but if you have it is not a problem as our next step is slotting the case, adding the two other coils and measuring any output.

Do you have a scope? I think scope shots will be very important in understanding the what is happening. If you are going to use a PC sound card as a scope you will need a big resistor on the probe to prevent burning out your sound card. Much better to use a real scope, you really need a scope. There are a lot of PC sound card scopes available free on the net if you are willing to take the risk but be warned, I used them for several years and in that time I have blown two sound cards when monitoring my Bedini SSG. In truth they are not very good. As a cheap alternative to a traditional scope you can get PC scopes that plug into the back of the PC and data loggers that you only plug in to download the info. Steve probably knows more about these than me but I am sure that they are far safer to use than your sound card.

There is a lot of tests we need to do.

The next test is to supply our 12 o'clock coil with our half wave input with the armature shorted, that is connect both brushes together with a wire and no supply to the armature. Now we are powering the armature with the transformer effect. Does the motor turn? and if it does what is the output from the generator coil at 3 o'clock? In this condition I expect the motor coil and the armature to be in opposition and so the motor should turn but could spin in either direction but I want to know what the output will be on the generator coil, does it change polarity? what is the volts and amps. We are now running the motor as an induction motor with BEMF so your amp draw will be lower but induction motors are usually more efficient, we will see. again scope shots would really help.

  The clock description sound like a good Idea. What I finally figured out a couple of days ago. Is that The Generator Is at 12 and 6. the motor coils should have been at 3 and 9. Because they are 90 degrees apart Right. After all this thime I hAVE BEEN MOTORISING THE GENERATORS WITH THE COILS IN THE WRONG PLACE. jUST ACCUSTOMED TO WORKING ON THE GENERATORS NOT A BRUSHED DC MOTOR. Two completely different phases.

  Yes the motor coil is at 12 oclock and the gen coil is at 3 oclock. i did have the gen coil at 9 but changed it to the 3 oclock position because the direction of rotation was wrong. It is rotating ccw.

   Reference to first paragraph The generators that I am using are the stock position of 12 and 6. but i was wrong in my thinking. Thats 180 degrees when the motor should have been 90 degrees to it At 3 and 9.
   
  Tomorrow time permitting Im going to work on this. Yes I did slot the case But its in the wrong place. Done a nice job on it too.

   Yes I do have a scope all I need to know is how to hook it up and read it.

If you have slotted the case, just make sure that the magnetic circuit does not cross the slot. With the scope just set it to AC on the highest voltage and then switch down the voltage till you can read the wave form then take a pic and send it to me.

Do you have skype? then I can show you in real time how to use one.

   Results of the last test you described.

   Motor coil at 12  and Gen coil at 3 oclock position. No the motor doesnt turn.
   
    motor coil voltage 1.5 volts 30 amps
    Gen coil  7.5 volts, voltage does swing negative. connected to a load .13 amps. (heater motor)
   
    Note this is with one end of the motor coil grounded to the case. If i connect the end i grounded to the case , right off the variable transformer the
    readings drop about in half.
    these tests were done with a wider feild pole that covers 3 armature slots. I tried the narrow one I had too but the readings were also about one
    half. So I put the wider one back in.---------------I am making another feild pole for the other gen coil to put in with the other motor coil. From the
    looks of it the slots in the case are in the right place for each side,just on the edge of the m-g coils.

  What do you mean in this first sentence. The coils come up right to the edge of the slots. Hope thats right. Think I can figure this scope thing out. Ill have to try and remember how to load up those pictures again. I havent done since the last picture I sent you 8 months ago.

Im going to try to work some more on this tomorrow.

There should be no slot between the motor power coil and the generator coil. The motor is in fact two motor/generator circuits, one either side of the slots.

There should be no slot between the motor power coil and the generator coil. The motor is in fact two motor/generator circuits, one either side of the slots.
    Thata the way I have it.

  Then when the slots are 180 apart. The armature dividing line would be east to west. With one circuit above and below the east west line.So the motor negative brush would need to at 3and 9 oclock position. The motor positive brushes would need to be at 12 and 6 positions.
Sounds reasonable. Whether it will work or not i dont know untill I try It.
With the motor coil center at Between the 1 and 2 oclock position and the gen coil between the 10 and 11 oclock position. The pos brush at 12 and the neg brush at 6 oclock position. it works really good using 1/2 wave rectified. It does pick up in speed as I add more load to the gen coil with the 12 volt bulb load bank.
So i removed the 12 volt bulbs and connected the heater motor as a load. It starts spinning a little slow but picks up speed pretty good then all of a sudden the motor starts to run wild. Increases in speed dramatically and the heater motor starts spinning faster until the circuit breaker cuts off. So we are on to something here. Something going on.
I have been working on this off and on when I get time. helping build a garage for a friend. I have got the other set of coils and pole shoes ready. I first need to figure out if I can get to rotate by changing the neg brush to somewhere around the 3 oclock position. So were still moving forward on this project. a little at a time.
The slots in the case do seperate the 2 circuits. Which I do have wrong according to where i have the m-g coils now. So it will have to be reslotted. again. This is the best place for the coils i can find at this time. they are close to the magnetic neutral line for the motor and gen axis as the armature reaction takes plac in seperate machines. Thats where im at, at this time. So were are making progress. trial and error.
There is most definitely a transformer action and IT DOES INCREASE IN RPM.I believe the motor speed is regulated by the load. From What I have seen at this point in time.

No, this wasn't what I meant but by all means check this out, you may find something.

What I did mean was to have the motor coil at 12 o'clock and the positive brush at 12 o'clock, the second motor coil at 6 o'clock and the negative brush at 6 o'clock. The generator coils would be at 3 and 9 o'clock with the splits in the case at 10.30 and 4.30.

Once we have all four coils in the device we can try having the motor coils in series or parallel and the same with the generator coils. The test with the motor coils in parallel and the generator coils in series should be interesting, will it be more efficient or not?

Keep up the good work as you are the only person in the world that is doing this, as far as I know. I wish Steve would give it a try.

The people that I have shared some information with are

Pault (he does not want to join us here for political reasons)
erfinder (he does not want to join us here for political reasons)
Turion (I never asked)
sucahyo (I never asked)
Peter Lindemann (he never replied to my email)
Obviously the other members of this private group have access to what I am saying.

Pault and erfinder are interested but as of now haven't done anything about it. erfinder understands the concept very well but is busy building his own device that works in a different way, I would say he has the best understanding of it other than me. I keep putting hints of the forums but am not getting a response. I know we are getting very close to being able to build this and get it working.

 I have all 4 coils in, the way you prescribed. The Holes for the gen pole shoes in the case I made a little longer so I can adjust either way. Preliminary tests is at 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 . The bulbs in parallel works better because the motor really increases in speed.
When removing power seems like the coils are still loaded because it doesnt slow down like it used too. Any way im going to try and finish out the last tests from your above post with some other thing i thought of this week. Got to put the slots back in too.

100+ volts, WOW :D Can't wait for the results, describe in detail the best you can. Compare watts in with watts out etc O0

Sorry for not being able to wait, are they 110v bulbs

    YES they are. Before any tests were done today. i put slots in another case and places for anther set of brushes. Well then i decided to transfer all the coils to that generator case. Just been one of those days. First it wouldnt run. Got that figured out . But now my voltage is down to 80 volts and doesnt spin as free. So will need to take it back apart and check each coil and its position with the armature slots along with the brushes.
It was working sooo good too. So will get back to you soon as I get that done. May have to put everything back in the other case again.

Once we get the voltage up some more all 3 bulbs should be llit up pretty good. But for now i have to get it back to where i had this am when i posted to you.

keep doing the comparisons with series and parallel although my gut says it will need to be parallel on the motor. Are you still using an 8v supply and what is the amps?

I still can't figure why the voltage is so high, I was expecting 24v output for an 8v input with the motor in parallel and the gen in parallel. With the motor in parallel and the gen in series I would expect 48v all tests with a small load. Under heavy load I would expect the voltage to drop. There must be something going on that I have not thought about, Scope shots would help me here. With everything in series I thought the voltage would be less than everything in parallel.

If your input is 8v at 30 amps or 240w, being able to power 200+ watts of bulbs is 83% efficient and is a very good efficiency. We are well on target for a self runner, In fact it should not be too difficult if this is the case. I was not expecting this which again tells me I have missed something. The only thing I can think of is that we are generating little or no BEMF in the motor coils and that we have three input coils on our transformer (two motor and one armature) and two on our output. It just does not add up ???
