Constant flux DC motor/generator.

[jadaro2600]

Yes and? Have you forgotten newtons third law. Action equals -Reaction. The conductor, which remains stationary, is acted upon by forces of the magnetic material. The magnetic material are acted upon by the reaction force of this. You perform some simple rules to get the forces and reason will tell you that the left part will mainly be affected by the left conductor side crossing the flux and the right part by the right conductor side. Hence the rotation of both sides albeit in opposite direction. If you don't get this logic then I can't help you.

There is nothing to figure out except for experimental data, I annoted everything clearly. The parts you think that should be levitating in the first design are either stationary in motor mode or glued to the rest in generator mode. My designs are meant to inspire and explain the concept in a very general way, not present an autocad and CNC ready model.

@ Broli
Sorry, It is not my intention to rain on anybody's parade. I just tend to think in terms of practicality.  I fully appreciate your thoughts and solutions for the puzzle at hand.
I can see how the posted design could work as a motor.  But why not a generator?
Do you believe that as a motor it would not have BEMF because of a uniform field?

Both of you make interesting points:  The similarity is this; With regard to the faraday disk model, If you rotate the magnet, no current is produced in the disk, if you rotate the disk, a current is produced.

However, if the magnet is rotated, a current is produced in the magnet.  Has anyone tested the strength of the magnetic field while the magnet is rotated relative to that when it is not?

In Broli's model, he suggests that it will have no generator action, but motor action, according to the posit, I posit a similarly, in that the ideal motor would not be an ideal generator.

These devices are not ideal, and for what it's worth, I might mention Betacells, a thermonuclear junctions to boot - most of which produce high voltage and low current, our counterpart here is the disk which produces high current and low voltage. 

Interesting, no?

If what Broli is suggesting is correct, then there is a field model which will create motion when a current passes through it, but when it is in motion, no current is generated.  There must therefore be some contradictory device which performs oppositely...

When in motion, current is generated, but when current passes through it no motion is generated.  This would indeed by a violation of some law somewhere.

Your design does not have the external circuit to trap the field so the charge just shifts the field and no work is done.
It is an interesting design though.

Below is a video of a wire with current running through an external magnetic field.  The wire gets as far as it can from the external magnetic field.  According to your above statement, the charge would just shift the field of the magnet and there would be no work done on the wire or the magnet.  As you can see in the below video, your statement can not be correct and there is work being done.  In boli's example, the wire is held stationary which will torque the magnet pieces and cause it to rotate.  Since the wire is cutting through the field twice, the magnet piece on the other side will rotate in the opposite direction.  The magnet pieces will counter rotate to each other with no opposition.

Nice video.
The problem is, this is not the same case.
The wire does shift the force lines to the other side of the wire, but they have no where to go so they build force and lift the wire.
You cannot just shift the field lines out and away from the magnets!

In a circular case however, the field lines can easily shift all the way around the circle and fill the gap left from the shifting field.
That's why no force will be generated.

The purpose of the video is not show weather the field lines shift out and away from the magnets or not.  It is showing how a magnetic field can torque a current carrying wire that is able to move.  Likewise, a fixed current carrying wire will have a torque on a magnet that is not fixed.  If both the wire and the magnet are glued to each other, then the forces are canceled.

If the left and right side of broli's last design where attached to each other, then the forces would cancel and it's not due to the field shifting all the way around the circle, but is due to newton's third law.  This is the reason for the left and right side not to be attached to each other so the forces are not canceled.

This concept is not hard to grasp in my opinion.  Testing will show if this concept is correct or not.  Broli's design is using newton's third law.

Lumen,

Here's another video for you to think about using the Law of LaPlace that supports Broli's concept, http://www.youtube.com/watch?v=wvScSTbly1c

The magnetic field is mostly confined between the poles (legs) of the horseshoe magnet and the ferromagnetic material in Broli's design is confining the magnetic field in a similar way allowing the forces to be in a circular rotation instead of just a linear force.  You can't have the conductor on a rail to pass through the horseshoe magnet to continue in a circular path, but in broli's design it is possible and is using the same concept as the linear device with the horseshoe magnet.

Edit:  Here's another LaPlace rail that can be easily looped into a circle without having to pass through the magnet, http://www.youtube.com/watch?v=_-kQans2rww
