very simple magnet motor
« on: December 27, 2006, 06:35:44 PM »
I have been working on the idea of a PM since I first played with magnets. I have tried many ideas, from moving toy train cars on a track to gearing several small magnets together. Even made a really large machine with a 2' diameter aluminum disk and used a 200 lb pull rare earth to try and power it in a kind of strange configuration.

ANYWAY  -  I read that PM is possible under current laws of thermodynamics with certain conditions present. It goes something like this. ' It is possible with two systems working the exact opposite of each other'

I cant remember where I read this and would love to hear from someone who has read the same thing.

ALSO - I have a design that uses one magnet. I've proven the concept and have constucted a model (not all parts complete).

Further posting will be done with pics and drawings. ( Ive worked on this design for the last 5yrs on and off, so please be patient). Its so simple and completely different from anything I've seen.

Ive solved the problems of sticking points but making the parts is really tough. I have the equipment, mill, lathe, etc. and its still really tough to form the parts needed. lots of trial and error.

if anyone can tell me if they have read what I did about PM being possile under current laws of thermodynamics, it would be greatly appreciated.

@iadcw  I have read several different all encompassing theories on the necessary conditions for a working PM motor.  One of which was to use the magnet's natural inclination to balance themselves to get past the sticky spot.   

I am very interested in seeing more of your single magnet setup since the simpler the machine, the better I believe. I am also working with several design ideas using different single ring configurations.  I also have acess to a 2 axis CNC machine if you ever need rapid prototyping done..  I can design the files for you based on your specifications and feed them to the machine for very accurate cutting.

Keep us up to date with your progress and let us know if you need anything.

Hi iadcw,

I have not come across the idea you described as  "It is possible with two systems working the exact opposite of each other."  but remember a Belgian patent a forum member here ,Lanca IV, mentioned in this forum. This patent works exactly as your quotation says: an electric (DC) motor is fed from a battery, the motor's shaft is hooked to a (DC) generator and the generator's output is connected directly to the same battery. See patent BE438189 at http://v3.espacenet.com/textdoc?DB=EPODOC&IDX=BE438189&F=0  and click on the Mosaics icon to see a Figure. (This is the only info on the patent's 'description', no other working detail is given.)

Looking forward to your further postings.

Regards
Gyula

Hello gyula,
did you not read the "Original document"  information ?
The only "important" info-which is not delivered : RPM ?


Hello iadcw,

Thanks for all the replys.

Konduct - Thanks for the offer of help. I will need to talk to you Im sure.

lancaIV - Thanks for the link but chapter 6 will need updating. There is another way to get past the 'sticky spot'.

I dont mean to be so vague right now and I cant wait to show and tell somebody what I have. Just a little longer. I need to make a few preperations to protect my work first.

I do have another question. Has anyone seen a PMM work. I think when I finish and this thing is rotating on its on, no matter how slow or fast or how much power it has. Thats the end of the search, right. Its kinda like invention of the first light bulb. It didn't light a sports arena, but improvements to the design, over the years and now it lights a sports arena

I don't think that there is currently undeniable proof of a working PMM.  I'm sure that many innovations may be made to your design to improve it.  The basic principles are the important part.

When I wrote my first post on a "very simple magnet motor", my wife and I were on a short trip to get away from it all. I had time to think about my idea and decided to offer it on this forum.

I have protected the idea by writing a theory of operation and taking some pictures and sending them certified mail to a lawyer friend of mine. He still has the letters I sent, unopened, in his office.

I decided that I have done enuf to protect my idea.

I got in touch with Konduct thru this forum and we had a very good conversation. He did some drawings in short order and emailed them to me. They are pretty good and show the basic idea very well. I will ask if he can post these drawings.

ANYWAY - here is the idea.

The idea is very simple and has evolved thru several models.
     Magnets attract metal. When you talk to a magnet company about magnets, they mention the power of the magnets in LBS of Pull. This LBS of Pull is always said to be against a 1/4" or thicker piece of metal.
     The magnets have a lot less pull against thinner metal. This can be proven by holding a 1/4" piece of metal over a magnet and then holding a knife edge over a magnet. You can feel the difference in the amout of pull. If you touch a thick piece of steel to a strong magnet, you have to  work to pull it free of the magnet. If you touch a very thin piece of metal to the same magnet, you can pull it free with very little effort. Also, thin metal attracts less at a distance than thick metal. This is the basis for my idea and design.
      My model consists of a center shaft with bearings on each end. 2 pieces of metal are attached to this center shaft. each piece is the same but a mirror image of the other. They are a 1/2 circle, cut so that one end is thick(1/4") and the other end is knife edge thin, and attached to the shaft at an angle to form a Ramp so that a magnet fixed in place will attract the metal and cause it to turn. When fixing this metal ramp to the center shaft, the thick part of the ramp will be farthest from the magnet and the magnetic attraction will cause it to turn to the thinnest part.
      This completes a 180 degree turn of the shaft.
       At this point, the other 1/2 Circle piece of metal is fixed on the shaft in the same manner as the first on the opposite side of the shaft from the first. 1 ramp will be positioned to be on top of the magnet and the other ramp will be positioned so that it is attracted from the opposite side of the magnet.
       At this point in time, the first 1/2 circle ramp has been attracted by the magnet (has turned the shaft)so that the thin part of the ramp is closest to the magnet and the 2nd 1/2 circle ramp is now positioned so that the 1/4" or thickest part of this second ramp is on the opposite side of the magnet and a little farther away than the thin part of the first ramp.
       Since the magnet is attracted to the metal and to the thicker part of the ramp, It will turn the shaft from the thick part of the ramp to thin part of the ramp and "jump the gap" so to speak to the thicker part of the second ramp. It will follow this ramp thru magnetic attraction from thick to thin and "jump the gap" again to get to the thicker metal and then follow that ramp, etc. etc. etc.

I had a model that turned 360 degrees(it jumped 1 gap) and followed the second ramp around but did not jump the second gap.

As I mentioned in my first post, the parts are hard to make. I tried to improve on the 1/2 circle ramps( with heat and a hammer to form the ramp ) and I ruined them (imagine that).

The models were made about five yrs ago. If youve worked on a project like this, you know how easy it is to get off on tangents and try other things(improvements, ha ha). I have thought about how the model I made then followed the ramp and jumped that first gap. It still amazes me to think of seeing it work.

Since that time - I haved moved and am now ready to work on this again as I have the time and the idea is constantly popping into my head. I have come up with a design to make all pieces adjustable so that I should be able to adjust things as needed.

I tried many different models using 2 or more magnets, shields, magnets with gravity wheels, and never had what I would call success. This idea and model is the only thing I've tried that shows real promise.

Sounds very interesting and could be fun knocking up a test Rig.
Should be easy enough to take the drawings and convert them to Gcode for milling out.

Look forward to seeing the drawings as will give a better understanding.

Sounds like a very good idea. The only thing that I wonder is will the metal pieces get magnetized over time?

Hi,

There are ferromagnetic materials that do not readily get permanently magnetized. These are mainly certain alloys of iron with Si and other materials. Such are conventional mains transformer laminates for instance, they could be used here for tinkering by cutting them to different lengths and bundle them together (and with
careful work they can be shaped into curved/bended form too.

Of course there are other metal alloys like the cores used for electromagnets where the permanent magnetism is also unwelcome over time. But these cores are much harder to work with here for getting the curved / diminishing thickness shapes.

Interesting idea to use small layers and stick them together to increase attraction.

I thought closing the loop on a horseshoe magnet also gives extra attraction. (not sure)

MrMag

In my model the shaft and magnet holder are aluminum so no magnetism. The 1/2 round plates have not become magnetised so that its very noticable.

Also,it doesnt matter if the formed metal plates were magnetized. If you could make magnets shaped as needed, the plates would be magnetic and my thinking is it would work better.

Something I havent done yet is use a shield on the magnet. Since I am working with a magnet to attract metal, I dont have the problem of the shield attracting to the magnet you are trying to shield the magnetic field from. ( did that make sense).

Another thing to keep in mind.

I am working with magnet force reacting to metal. Far different than working with magnet against magnet.

the variables are, size of the magnet, angle of the ramp and and distance from the magnet. These are the important things. The idea is to use the pull of magnet to metal to finesse past the gap from thin to thick. I've done this(jumped the gap) wih a very small model. It actually seemed to speed up a little when it jumped the gap and started following the second ramp. My problem was both metal ramps were not the same and setting an equal distance on both sides was not possible since both ramps were different.

you would have to be lucky to do a CNC design and get it right the first time.

I have come up with a design were variables (as I see them) are adjustable. Im making parts now and will post the results.

I do have a question - Has anyone seen a design like this.
