Hi

In this project, spiral config. becomes essential ...

@Brent and Hypercom:  Thanks for the information and welcome to the Forum.  I look forward to seeing how this thread develops from here.

Was just thinking about it, do the homo polar motors only cause electron flow outward from the center?
My point is, that is the way I have always seen it described. But if you spin it the other way, will current flow from the outer to the center?
Like left hand rule.  Now if we can get one conducting plate to be in a situation that the current flows outward, and another that flows inward, we can eliminate the outer brushes all together. Then make a big magnet and plate club sandwich that has the appropriate plates connected physically on the outside and inside in series. Then just have brush commutators on the shaft at each end.

In this discussion you can find some ideas, some answers ...

Here is another example to greatly increase the efficiency of the system.

Hey Hypercom

I get the basics of what happens in these ideas, but the question is, does anyone have any knowledge of if the current can only move from the center of the conductive plates outward, or can it be made to have the currents work inward to the center from the outer edge?   If it can be done, we can eliminate the outer brushes all together, of which seem to be an issue with these devices.  Of course the mercury, or other liquid metal contacts will work, but for the common man, we dont need any more mercury in our lives.

If the direction of current in the plates can be reversed, then the connection to those plates can be done in a much better fashion.  Lets say we have a 2 plate/magnet sandwich, and the commutator for the first plate is connected toward the center of the plate. This plate will have currents flowing outward from center. Then we connect the outer part of the first plate to the outer part of the second plate in the sandwich, physically, via wire, copper tube slice, how ever, but the second plate has to be arranged in a way that its currents flow inward from the outside.  Now we have the connection to the second plate also toward the center of the plate or shaft with a commutator. This would reduce the friction and commutator surface speed and allow more pressure to be applied to the brushes.


But if it cannot be done, getting the currents to flow inward instead of outward, then this post is nill.  =]

I dont quite understand the drawing above, but I will check out your thread suggestion.
