72 contact rotation ~~ BUILD LOG~~

[unimmortal]

Jim, looking at your commutator problem - if you could somehow make/put a race around the bottom of the commutator to support the brushes, you could do away with the complete top cantilever setup. This would also mean the brush contacts would be better stabilised between two points and you'd get a significant speed up. Just my 2c...

Hi Jim,
Rotation,,,, funny thought,,,,, since all of your coils are fixed stationary to the commutator that you have built and it is the brushes that are rotating, why not hold the brushes still and rotate everything else around? You would need slip rings for the output coils but all in all I think that would provide you with an RPM independent test-bed.

unfortunately that doesn't resolve the issue as the brushes need springs to keep pressure as the brushes slowly degrade, and to absorb and imperfections.  So even if the carriage was solid or in a track, the springs lose compression at high speeds as the brushes get pulled back.

Webby-  Your solution is indeed possible as I considered it.  I decided to wait on that method as balancing a heavy coil contraption to spin quickly seems like a lot of work to test this unproven method.  

Also, my core and coil design needs modifications..  Rotating the field like this creates a rotating field in the center hole that jumps across 180 degrees-  like spinning a bar magnet flat inside.  But my output coils are not setup to interact with that field well.  

I'm just gonna do some testing of different strategies before building it out further.

Hi Jim.
Good that you are looking for answers. A few months ago I read an interesting article by a researcher [https://ua-hho.do.am/index/static_electr...ators/0-51 ], which suggested that Figera in the generator he sold in 1902 used commutation of the armature windings in the rotor by analogy with a DC motor. These motors have the disadvantage of heating the armature windings if the cross winding is made in the slots. But if we assume that the armature core rotates and the magnetic poles are stationary, then if we rotate the brushes around the collector, the core will be stationary and the magnetic poles will rotate. So why can't we insert this armature into the stator core with slots where the generator winding is wound?
Heating the core of such generators is a natural phenomenon. Turbogenerators use very powerful cooling to work. Maybe you don't need to look for a separate configuration, but try to implement it using existing solutions: a stator with a three-phase generator winding and a suitable armature, only the winding should be done on a larger number of armature coils. Your switch is just right for this.

Sorry for imposing my views, but I think that the generation of electricity by modern engineers is done on the basis of good knowledge of this subject.
This researcher has an interesting video showing such an option. In any case, it will not be possible to create anything by eye, an engineering approach is needed. My friends tried to order a calculation of a generator for a mini hydroelectric power plant in one design office, the cost of the services was very expensive, they refused this idea. There is also an interesting video [

Yes the researcher you mention (rakarskiy) is indeed onto the solution as well.  I have attempted such configurations and posted videos of the results.  And the idea is indeed feasible.  But there are a few peoblems in design that need to be worked out..  Finding an armature with enough slots to accomidate 36 coils is difficult, then rewinding it with 72 taps is even more difficult given the limited space for the taps and overlapping.  

Not to mention the difficulty spinning the brushes at high RPM.  So we have a choice here,  spin the prushes, or Spin the commutator along with the whole coil assemblies.  Either way has drawbacks.  But the general presented idea is Spot-On and I believe it will work..

Last night I tried a solid state configuration and verified this method does indeed induce like a generator, where the output peak aligns 90 degrees out of phase with a center pole of the primary.  Which is quite exciting.

There are many different configurations that use the same principle and I think it can be done with electronics with no spinning anything.  I encourage others to start experimenting with this as I continue on my quest!
