The TPU uncovered? (A PROBABLE technique.)

It looks to be a good idea, but I think your approach with reed switches will encounter a mechanic speed limit. IE the spring tension in the reeds (I am assuming mechanical reed switches) will only react up to a certain speed, then they would attempt to float, in similar conception of mechanical points on an internal combustion engine. At this point, which will be low in comparison to solid state, the reeds will not be able to react fast enough to the field.

However, I will NOT shoot down the concept, in that we do not know yet what speed is optimal for the TPU. Give it a try, and post the results.

A potentially good idea!

Is it even possible to hijack a thread? "Speak up", "shout and be heard", (ahem...cough...gasp..... Sorry, choked on a dry cliche'.).

@everyone

Just an update for all on my thinking, with explanations.

Concerning the rotating field:

About the TPU, we know much, yet little is HARD data. We know, for instance, that a rotating field is necessary to it's inherent operation. Yet, that is ALL we know concerning said field. We have made plausible guesses, but remember that is ALL they are... Plausible, or probable, not proven hard data.

Keep in mind that in anything we desire to accomplish, there is always several ways to accomplish the same goal.

How can fields be made to rotate? Rotating fields are in common use today, mainly in polyphase power (motor) or generating (alternators/AC power production) applications. Find out why they rotate, then imitate already proven technology if necessary. Understand that they cannot make a motor spin >inductively< with only one frequency at single phase, and that is the reason for starting capacitors etc.....(I refer specifically to AC induction motors, not DC or "Other") By the "etc.", I am thinking specifically of those little AC fan motors, you know the ones I am talking about, with one big fine wire single phase coil, an iron/poured aluminum cage rotor, and out in the middle of knowwhere, a 1 1/2 turn very heavy gauge wire soldered to itself???

(BIG HINT, think about what you have seen on the small motor, and go examine the TPU pics in JDO's newest thread, and see if you notice what I noticed.)

What WE are facing with the TPU is a rotorless induction motor, where the fields itself are rotating. Think of it in those terms. Otto, you stand vindicated in part, as the controls may well need phased AC.

However, I still think the AC component is developed inductively from the input.

     I really believe that you need the pulse energy to travel through the coil copper not apply the pulse to the entire coil.   Just think what one fm pulse does.  It travels at near the speed of light and rattles magnetic fields on antennaes in a radius of hundreds of miles all at the same time and everything in between.   Just from one little spark in a vacuum tube.  Now imagine instead of all that energy radiating out very uncontrolled you cause it to go around in a circle.
Or collapsing inward across a pancake coil or spiraling through an ion gas filled bulb.  DONT EVEN THINK ABOUT MOVING THE ELECTRONS OF THE CONDUCTOR due to an impressed voltage.  You can do that till you are blue in the face and you won't get anything but conventional current.

This has been my exact line of thinking for a while now--I can say with 90% certainty that you will not see these effects with a ferrite core (ran LOTS of tests, nothing interesting happened).  Can you elaborate on what you saw in the pictures?  It might help us converge on a solution faster.

A picture is worth a thousand words.



If they are not the control coils, then they would be loading coils for the control coils like in my mosfet circuit.
