Magnetic Ring- Domain Flipping. Interesting!

[Jim Mac]

This is the setup..  The magnetic domain of the rotating tube is constantly changing while the magnetic field stays stationary in space.

Very interesting!  Going to experiment with it..

[Jim Mac]

One may think if I placed a single polarity magnet outside the rotating tube, it would act like a universal motor and the tube would spin.  But it doesn't.

There is a balance as usual..  The steel tube IS attracted and repelled to the outside magnet, but there is an equal force of the steel tube attracting and repelling to the inside magnet in the reverse direction.

But when I place bolts sticking out, now an outside magnet does move the rotor.  Just not continuous rotation.  

Lots of things to try here..

[Jim Mac]

As stated, I hold a stator magnet by the metal ring at the blotch wall, it will not rotate.  But if I attach bolts sticking out, it does attract and repel the bolts.  So it seems the rotor needs magnetized extrusions or separations like a universal motor armature.

Notice the separations in the laminates:  Motors are not designed with the coils inside a solid smooth tube.

   

So Next I will try mimicking this.  I will print a ring with laminates on edge. I am not sure this will work though because the laminates are separated. If this does not work, I will need to try with the steel ring and the laminates all touching the ring.

well I built 3 different rotors to revolve around the magnet.  2 with nuts / bolts and 1 with laminates.  I tried all combinations of numbers and achieved just about no cogging on some patterns.  But it will NOT spin with any.

as soon as you bring a magnet close and create a positive torque, a counter negative torque manifests in the metal passing the magnet that balances each and every time.

At this time, I am concluding that a Universal Motor can spin because the rotor armature does not have to enter and exit a magnetic field to get polarized, the coils wrapped on the rotor polarize the armature.  

I may come back to this if I get a new idea to try.

Edit-  BUT I still do think this method can bypass Lenz in a generator.  We can reverse Lenz, but then the same manifestation of restrictive forces in the metal passing the magnet work against us, Thus balancing.

Hmmm.. bypassing the magnet isn't the actual cause, as bypassing by it's own (except for friction etc.) does not lose energy. However, bypassing in the reverse ratio concept means to go into position for a reverse lenz event. But going into position is already inducing current, but with lenz drag. Thus balancing.
Like you said, use switching to extract energy only during the reverse lenz event. Or use it balanced, with close to no lenz drag in average.
It should also be said, in big designs one could use electrical magnets, rather than permanent ones. Start up with an external power source, once it runs, switch 50% of the output to be used to power the electro-magnets. Cause nobody builds megawatt generators with permanent magnets, way too expensive and unpractical.
