Are there any running magnet motors?

[laserman]

Hello all, i'm new to forum and magnet motors.  I have built a perendev replica that is an excellent motor break. It has no possibility of working it works better than disc brakes.  I am addicted to this obsession.  I have seen many computer simulations of running magnet motors but the only one that makes sense to me was the Bowman design.  I am attempting a design similar to it currently.  I have a laser engraving system that is capable of cutting 1/4" acrylic and it is a real nice tool to have.  I would be willing to help others prototype their designs for a nominal fee or for trade on their services. I work with Corel Draw x3 and can import many file types.  Contact me directly at laserman (at) bend cable (dot) com no spaces.  any link supplied to me i will follow like a blood hound!  Thanks to all in advance.

Have a look at the MFT:

build a motor with lots of power, but doesnt use much,and have it power a 3Kw gen please , and ty.,oh and make sure can power the motor, close the loop:).

I have seen first-hand three magnetic motors running and have written
cost feasibility and reproducibility reports on all three. Two of them
I had in my lab and my staff used the inventors' plans to build several
working replicas. We also went and saw, first-hand, the Perendev
device.

All three designs used "Rare Earth" magnets (Neodymium, or more
correctly stated, Neodymium Iron Boron or NdFeB) and our various
reproductions used NdFeB, SmCo and Ferrite magnets. We did not attempt
to reproduce the Perendev device because of its design proximity to one
of the other two.

The results were always the same: they all run down. Under load, they
run down very quickly. It doesn't take very long for magnets to lose
their magnetism when they are constantly being put in opposition to one
another.

Received this from the Keelynet forum.

This has been my experience also. There is no overunity to be found in permanent magnets.

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.

This is incompetent gibberish.

I have never seen a working permanent magnet motor (except for Finsrud's about which I still have certain reservations).

However, show me a self-starting permanent motor making several full turns and don't bother at all about magnets running down. Anyone concerned with the energy necessary to magnetize the magnets or magnets getting demagnetized while the pmm is working doesn't know what he's talking about.
