@BEP

Bam, slam, boom, boing, blump, nay say, no no, never never. Hope you're happy now. Lol


That does make me feel things are back to normal  :D Thanks!

That incline when turning will move the rotor armature from left to right, right to left over the coils making the shifting field above the coils.

Incline? Armature?

Sorry, there is no incline or armature. There is a rotor that shifts an unchanging flux density from one coil to another and back for each revolution of the rotor. ‘Armature’ implies either there are windings on the rotor reacting to a field in the stator or the windings on the stator are reacting to pole switching at the rotor. Neither is happening.

Quote
Usually an energized armature will want to rub against the coil armature as close as possible and over the total exposed surface area, whereas in your design, the armature will cover maybe 20% of the surface area and slide left to right, right to left.

The rotor surface covers 100% of the left portion of the stator and about 78% of the right section. Each only when the rotor was making magnetic connection with that stator section. The sections are 180 degrees apart. It is not energized unless you wish to consider a non-rotating or changing magnetic flux as energized.

Quote
good point of your design is the way the rotor is shown, it will be able to counter a higher level of drag because the rotor is more "cutting through" and not the conventional "gliding over" any potential drag condition.

Sorry, there is no ‘cutting through’ or drag. The original generator had a third coil. This coil was on the stator section above the magnet. I kept trimming, grinding and rebuilding until the output of that coil was practically zero regardless of speed or load.

I suppose I’ll never be able to relay useful info. It seems most have lost the ability to visualize a 3D object from a 2D sketch. Sorry, I don’t mess with 3D. It is pretty enough but the machinists use my prints well enough. I work in AutoCad but convert to Paint so I can post. Too much is lost.

Think of that rotor section as a coin spinning on the tabletop. Just before it falls the spin axis tilts. At that point the spin axis of the coin is oblique to a perpendicular line from the tabletop. From the stator’s view this action is a linear motion, constantly shifting from one pole of the stator to the other.

The magnet sees NO change in flux density. Lenz is no longer part of the equation for the magnet.
Drive the shaft with a small motor. Take what you need from the stator coils until they fry.

So sorry to say but you DO have a good idea there. Lol

Thanks. If you only knew.  lol

I tried  :)

@BEP

Well...........At least I got the first part right. lol
Man did I miss this or what.
Nah.... I don't think I got it that wrong.
My use of the word armature was simply to explain that the rotor is not a magnet but is magnetized by one side of the disk magnet. Also, the two coils look wound on an armature regardless if laminated or not. The incline is your angled rotor going over the coils twice per rotation.
I then compared it to a standard full rotor and mentioned that since this design has less "armature" ratio turning over the coils it may need more rpm's to produce a better output.

So I have two questions.
Do you think the center magnet located on the shaft has enough magnetism to then permit having eight coil pairs all around the rotor as a full stack that would give eight times more output per rotation while turning the rotor should not expend more energy. If yes, you could then add two, three or more stacks to increase even more the output.
Something like the Lutec stacks.
Anyways, sorry if what I posted was not clear enough.

Nope, still no incline. In the stator's view there is no incline. The same amount of flux is connected regardless of the rotor's position.

Thats a 'run before walk' statement. There are improvements but if you jump to the improvements you will probably find nothing works and move on to something else that has no chance of working at all.
I do that all the time  :D

Lutec? There is nothing like this out there.

Multiple stators ( making a three phase generator? ) will cause problems because flux will take the shortest/best path. You will still only have one set of poles working.

Enough magnetic force with this one magnet? Nah. Not enough to run your space heater but it should be enough to make you see the idea works. ("Killing the dipole" is B.S. for 'I got nuthin and want you all to think I have sumptin')

The mistakes in clarity are mine. I know you to be high in mechanical visualization. If you aren't screaming and jumping at this sketch then no one else on this forum will see anything. Not that they wait on you. Just they don't have the ability.

I know I don't have one at this stage for photos. It was hard to make by hand. Might be easier to strip a current one....

    The question here is what is going on when a magnet flips over magnetic dipole moments in a piece of steel.  Is the energy coming from the magnet to create the magnetic domains or is it coming from the atoms responding to the magnet.  Lets say we just put and electromagnet on the field pole.  Then cause current to flow through the solenoid windings and change the magnetic flux density inside the steel core with the stator coil open.  This will require energy investment by the rotor but the coils on the rotor are two chokes so that very little current flows just converts voltage to magnetic flux change.  The impedance of these chokes is such that current is resisted and all work goes into magnetic core saturation.  In other words all current is choked by the impedance of the rotor chokes.  Like a primary on a 60hz power company transformer with no secondary current messing with the impedance parameters of the circuit.
Unlike the secondary of the rip off power companies mess on the pole we abruptly open the primary just as the choke coil cores saturate.  The magnetic field in the stator now returns very quickly to unsaturated conditions.  This shut off is timed with the close of the connection of the stator coil to a capacitor.  As the magnetic field collapses around this coil  we get a kick for free.  We need the power companies voltage not there frigging inefficient secondary currents.

This will require energy investment by the rotor

I don't know about the rest but the above statement is incorrect. Stick a motor on the end of the shaft. The only energy needed to rotate the shaft is friction of the rotor mechanics, provided your flux shifting is equal throughout the cycle.

There are no rotor chokes on any version. Capacitors come later. They are not required to prove the point.

Lenz does indeed play a role but ideally only at the coils. The coils can become hot  ;)

Hysteresis of the stator arms is important. If you want to get over that, to a limited extent, use the same principals used in a magneto. Then you will dramatically increase output power and speed operating range. Again, I didn't offer those improvements because we always want the latest and greatest, don't we? Do that and your build will fail and one more person will think I'm an idiot.

Hi BEP,

Thank you for showing your very interesting setup, I like it!

Your explanations included in Reply#121 helped in understanding why the flux does not change in the  stator leg on the right hand side going to the right hand side pole of the ring magnet. Putting this explanation otherwise, at meaningful RPMs (say above some ten or hundred or so) the flux in the right hand side leg will be constant because its value AVERAGES out to a certain value from the alternately facing or not facing rotor and stator areas as if there were always a closed magnetic circuit with a certain (static) flux value of the ring magnet while the flux changes of course in the left hand side and in the middle legs (shown with the coils) of the stator. Very clever idea indeed. 

So in the stator leg with the coils the flux changes from a very low value (in case of using materials with low remanent flux)  up to the AVERAGE flux set up by the ring magnet strength and the air gaps and the permeabilities of the oblique motor and the stator materials. This flux change will induce voltage in the coils and current if a load is connected.

Question arises what happens with the flux created in the stator legs by the load current?  I think the two triangle facing ends of these stator legs with some air gap between them are meant for closing this flux within the two legs, is that right?  If I am not right then why are the facing triangle shaped leg endings needed?

Thanks again for sharing and wish you also Merry Christmas.

Regards,
Gyula

The triangle shapes (feet - I call them) serve two purposes.

1. Enables smooth transition of the 'concentrated' flux from one stator pole to another.
2. In this level of design - allows the 'Lenz generated' flux a connection return path so it does not try to go through the magnet.

I'm not sure what you see with the 'averages' part. The first attempt had only one coil on the far left. Both stator arms were still there. The basic idea is to continue a path for flux connection but move that path in an alternating fashion, through one stator pole then the other and back.

Basically a magneto (none German version) but the rotor axis is rotated 90 deg. on the axis of the rotor.

     My rotor doesn't move BEP unless you want to use it for a voltage regulator. ;D  I got to refer to Tesla's efficient ozone generator.  Notice that introduction of power from the mains is through two chokes charging a capacitor.  This is a series resonant circuit charging a load capacitor.  The chokes impedance resists current changes while it does not resist voltage.  The power factor who gives a shit the capacitor charges cause it likes voltage and could give a damn about current.  Of course there is ohmic losses but how much resistance does big fat wire wrapped around a piece of steel heat up?

Sorry Sparks

I thought you were talking about my design. I offered it as one way to avoid Lenz law problems and still use the positive aspects of Lenz's law.

While cancelling Lenz's law is ridiculous (IMHO), avoiding the problems can be done more than one way.

This idea is a more mechanical one and should be easier for most folks to understand.

The heat generated in these coils is from the common reason. - Eddy currents. A later version avoids the heat better but I haven't found a need to go that route, yet.

This is a very old project for me. While it should be one answer to the stumbling block for many my current project  uses no coils or electronics to generate torque. I'll be concentrating on that most of the time.

Ahh!

I see what you meant by averages....

Averages require a range of varying data.

The integer does not change. There is nothing to average unless you are talking about the smallest of gradients. ( on the stator section directly above the magnet.) This is where most of the work had to be done. I tried adjustable gaps at each stator/rotor connection until I found the right gaps.

Basically I used the generator as a lathe and hit the rotor with a file until I found the balance.

Hi BEP,

Thanks for the 'feet' explanation.


I'm not sure what you see with the 'averages' part. The first attempt had only one coil on the far left. Both stator arms were still there. The basic idea is to continue a path for flux connection but move that path in an alternating fashion, through one stator pole then the other and back.


Probably the 'average' for the flux is not the most fortunate but I meant the followings:

The highest flux value occurs in the stator leg on the right hand side (and at every part where the magnetic path is just closed) when the rotor is at standstill and one of its area is facing one of the stator feet.
And when the motor is started from standstill the facing areas move away for a half-turn time, so the flux in the right hand side leg should get reduced from its earlier value. 
Then comes the next facing rotor stator areas see each other so the flux increases towards its earlier (maximum) value (but cannot reach it already because the rotor-stator areas see less and less facing time due to the gradual speedup of the motor).
When the driving motor finally speeds up to a constant value, the flux in the right hand side leg (and in every other parts constituting the closed magnetic circuit)  will also be constant (provided the facing feet and oblique rotor areas are already fine tuned as you described) but this already constant value flux will be slightly less than the flux value referred to above at standstill. 
This is how I used the flux 'averages' to a certain and constant value.  At startup the flux is at the maximum and during the speeding up time it gets a little bit reduced from its maximum value (of course I mean but a small, practically not important reducement in flux strength).

Have you thought of going for the OverUnity prize money with this design? You would certainly deserve it!

Thanks,  Gyula

@gyulasun

It seems you have an excellent understanding of this device.

I'll not go for any prize. I've suffered through that before. Do not forget I am not claiming overunity.

Some details you may not be aware of:

1. At one end of the speed spectrum the flux shifting lags. Beyond a certain point it leads. I suggest you use the output to feed a PWM control to drive the driving motor. There is no 'runaway' scenario. None I've seen.
2. There are many improvements to this that I'm not sharing at this point. The inventors of the magneto deserve the highest credit for these.
3. Some circuitry is still required. This makes this device a problem for OU researchers because most think in terms of the circuitry and get lost in complexity. If it is complex then it is a joke. Then I am at fault.

The best application for this would be wind generators.

So make a wind generator! Or power your soldering iron or laptop from it. But be prepared to do a great deal of work before it is useful to you   ;)

I'll continue on my other project.

Many thanks for the tips, I understand them.  :)

The PWM control sounds especially useful for the wind generator case where the RPM can always change by the wind.

I can understand your refraining from the prize for this device. And I hope you will disclose your other project when you feel like to and when it is appropiate, I certainly look forward reading about it!

All the best,  Gyula

Somewhat related?
http://www.google.com/patents?id=qog8AAAAEBAJ&printsec=abstract&zoom=4&dq=4780632

Lindemann's comments on the thing:
"Thank you for your kind and insightful remarks. With regard to your post about the Jim Murray Generator design, I have known Jim Murray for 20 years and we published this patent in Borderland Magazine back in the 1980's. All of the people I worked with in Santa Barbara, including Mike Knox, Eric Dollard, and Chris Carson, met with Jim Murray a number of times after I moved away in 1992. Jim and Eric subsequently solved the solid-state method for converting reactive power back to real power using Jim's methods applied to Eric's FOUR QUADRANT THEORY of electric waves. All of these things you mention have already been accomplished.

While Jim has built working models of this generator, getting all of the electrical and physical resonances in phase is tricky. The machine does NOT exhibit drag free operation until these conditions are all balanced and synchronized. Still and all, it does PROVE that electric motors and generators are NOT converting mechanical energy into electrical energy. The First Law of Thermodynamics does not apply to properly built motors and generators. For those of us who know the truth, this is not a problem."

I became familiar with that patent about 25 years after I built the first one of mine.

About the only similarity is the rotor design. The best I can tell that patent describes just another generator basing its entire function upon the use of Lenz's law, as conventional generators should.

I can imagine problems with 'tuning' on that design. It probably had multiple speeds where it worked best but those probably changed with load and load types.

It is very likely that the patent shows a generator that could be used as a motor, albeit a poor one, or an electromagnetic brake. My design will not work as either. It will only generate, unless it isn't built correctly. Then all bets are off.

The only tuning I've used is to slowly shave/file the rotor to provide as little ripple as possible, on the stator just above the magnet. This was done with a temporary coil, not shown on the sketch.

Mine does prefer to run at certain speeds. If I remember correctly the speed preferred by the one I show in the sketch was between 450 and 500 rpm. So if you built it be prepared for it to shake itself to death until you perform some basic balancing (do not use ferrous weights!).

If you're not using good construction with 'real' bearings (nothing special just good basic construction) the thing may eat itself when you run it up to a speed that shows promise. I always try for no more than 2mm clearance between the rotor and stator. So the faces of the stator and rotor are not flat.

So other than the word 'oblique' being used there aren't many similarities, in my opinion :)
