Permanent magnet motor

[ayeaye]

I tried to make it in a simple way. A hook made of paperclip, hanging from somewhere, and on it rotates a small cardboard disc. From that hang two magnets, with north poles against the north pole of the stator magnet. The thread was fixed to the magnets with a mounting tape. Cannot be made that way, friction is too great, cannot be made any way.

I have nothing to make such thing from. Needs some very good bearings, whatever they would be. And yes, the force is likely greater, the closer the revolving magnets are to the stator magnet. But this again needs some stronger construction.

I hope that Jim36, when he tries his magnets with a circular field, would also test this design. Because when it is made similar to the homopolar motor, the mechanical design is the same. Or is it? We see then which of these work, if any. The most likely reason for them not to work i think, is again that the force is not great enough for continuous rotation.

But who can do that and is willing, please test it. Because this design is not tested, and it is the simplest. No matter how senseless one thinks it may be, it has to be tested for the sole reason that it is not tested, even if it fails.

Below are drawings to illustrate what i described.

I don't know why i started to talk about this. I tried hanging a magnet from a copper wire, hanging it from a hook, to prevent twisting the thread. No continuous rotation. If the force is there, it is so small that it is not useful. Or there is no such force, i cannot say when it's not experimentally proven.

I created a mess, sorry, try to bear with me.

The drawing revolving_poles_motor.jpg is not likely right, i think it works only when both magnets rotate. If it does that is.

But i don't think now that it's something worth trying, or worth considering. All what i said previously remains valid, it is only asymmetry of the field which can provide overunity in a magnet motor.

Jim36,

So you should try this design similar to homopolar motor, with your magnets with a circular field, your original design doesn't work, unless there is some special effect. Which i no doubt there may not be. But when made like a homopolar motor, it will rotate continuously, provided that the field lines are perfectly circular. Because this is completely asymmetric.

But, it is most likely impossible to make magnets with completely circular field. Because whenever a magnet is bent, like to half circle, some additional poles appear. And the same thing happens when one tries to make a circle using many magnets. The poles of some of these magnets become tilted. My experiments also confirm that.

So i don't want to discourage you and i really appreciate the effort. I also try sometimes senselessly much, to test a possibility not tested before, as this thread may also show. But i think most likely you cannot achieve continuous rotation. Because the additional poles make your field something else than circular, the negative forces come into play, and the positives will not be enough for continuous rotation. As my experiments show, there is overunity in permanent magnets, but not enough for continuous rotation.

So magnet motors, after all, may not be worth the effort. At least i think so by now. So it's better to switch to basic experiments with a coil, like my negative discharge effect experiment.

I'm sorry, some things not known to me confused me.

Hi Ayeaye,

I've been on vacation for bank holiday weekend (here in the UK) so couldn't reply.

There is no need to apologies, you have been trying some good experiments and figuring different things out, now you have come to your conclusions.

I have myself tried to make a circular field out of many small disc magnets which as you say doesn't work as you have flux leakage due to tilting. I also crushed neodymium magnets mixed them with epoxy resin set in 2 'C' molds, I then allowed the resin to set while re aligning the material with small magnets fixed on the start and finish of the 'C'. This worked better than my first attempt but still had some flux leakage (I tested for flux leakage with iron filings and a compass).

I think I will still attempt the homopolar magnet motor as I have seen a video of this type of magnet in Russian with no flux leakage.

I will post the video here once I find it again.

Jim36,

I think magnets with a circular field cannot be made, and the russian video is likely a fake. But then say it's possible. Then it's obviously very difficult to make. Say you can get these magnets for $400, or maybe for $1000. You will make your device and it shall work. But what's the use of it? No one will replicate so expensive device. And these things cannot be proved, by video or by any other means. They can only be replicated. So what's the sense of all the effort then, would be yet another questionable evidence, would stay somewhere and gather dust like hundreds or thousands of such devices may already do. Which may work.

This is why i say, we need something which can be made cheaply, and easily enough. So they would be replicated at least a few times. And magnet motors are evidently not such things, they are expensive to make. Except some simple devices which only show overunity, like my experiment did. So what concerns permanent magnets, then maybe it's rather better to concentrate on these. To say to these who say that there cannot be any overunity, why don't you use a few minutes of your time to try these.

@Jim36
I missed the pdf in your first post, could work or the field might just flow around the magnets and not do anything.  Interesting attempt at making your own magnets, you beat me to the punch with that.  When I thought about it I figured that you could test by simulating the magnet electrically with a squirrel cage (see pic), you would just need the cage, a variable resistor ,and a dc source.  You could also center your mold/epoxy/magnetic powder and energize the cage to form your magnet.  Also a question,  I though that crushing the neo would demagnetize the material, did it lose a lot of its strength? I had an idea for a different type of motor but it would also require me to make my own magnets.
