Are there any running magnet motors?

[hartiberlin]

With the MFT you can have more positive torque
than negative torque,
look at this FEMM simulation LUA force graph:



This makes the magnet motor run.
But you need the special flux gate setup with the iron ring around
the magnets
to allow the flux gate rotor to pass the fluxgate with acceleration.

What most experimenters conveniently forget is the amount of energy it takes to make some material magnetic. They see something working for a short time and think it will go on forever if only properly adjusted.

Once that initial energy is gone the thing stops, yes Omnibus, even a SMOT. It may take a long time if the opposing forces are not too strong and only invoked for short periods, but it will happen.

It takes energy to make a hammer, but the hammer itself do not store that energy to be used later for pushing nails into a piece of wood.

It takes energy to magnetize a (soon to be) magnet, but the magnet itself do not store that energy to be used later in attracting a piece of iron or repelling another magnet.
If we use say, 1KJ to magnetize a NIB, it doesn?t mean that the magnet will be depleted after doing 1 KJ of work attracting 1000 times a mass of 1 N from 1 m of distance. Magnets do not work this way.

Magnets loose their magnetism only if they are exposed to SEVERE adverse fields. Please read carefully and understand the following articles:

and very specially this:

I hope that this help to clarify once and forever some of the misunderstandings about magnetism in general and permanent magnets in particular.

Hi Stefan,

I agree the computer simulations confirm that permanent magnet motors are viable. The problem is that the simulations are done under idealized conditions. In practice, however, equal symmetric pieces of permanent magnets give rise to quite disparate magnetic fields around each one piece. This throws the experimenter into daunting problems when trying to put in flesh and blood what the simulation has shown and produce a working device.

It's true that it is during these last decades that we are able to confirm theoretically, through computer simulations, that 700 years old ideas are in fact workable. What is needed now, and there are several very promising projects, is to make it so that many independent researchers can reproduce in their labs working perpetuum mobile's. (Of course, no one can tell with certainty that such haven't been demonstrated earlier, even centuries ago, and have been lost for humanity for various reasons.)

Thanks for the good explanation and links. There are people here, however, who would never understand this and will keep pouncing their incompetence on the forum as @hansvonlieven continuously does iin his politely arrogant manner. This has to stop and efforts have to be directed towards more productive activities leading to sooner replication of the perpetuum mobiles based on permanent magnets, perpetuum mobiles whose viability has already been confirmed beyond doubt.

I don`t think that there is incompetent people in this forum. Remember that none of us, absolutely NOBODY, is an expert or "professional" in the field of OU/FE/PM, else we would have many working devices to enjoy. No way, no working/usable device to power our home/car/appliances/etc. yet.
In my opinion, all opinions are valid. Take what you think is good or useful for you and discard what is not. We are all here to learn, to share, to exchange ideas (good and bad ones).
I`ve seen many threads in this forum with almost 100 pages and countless messages of people insulting and discrediting each other ideas/thinkings, discussing if OU/FE/PM is possible or not, messages completely off topic. ?Is this way how we plan to "save the humanity"?. I think NOT.
I personally enjoy when I see here a new idea/plan/link but is very sad (and a waste of time) when I see threads which appears to be written by two ladies who don`t know what an orgasm is.

Sincerely yours
Noble Wolf
