Taco Shell Coil- Same Polarity Both Sides
« on: January 06, 2023, 03:39:09 AM »
Brainstorming how to make a coil with the same polarity on both sides..  Came up with the "Taco Shell Coil"..

Many have tried double-inducting a pickup coil with both the prime mover coil & the rotor, but it never works well because the 2 polarity pickup coil gets inducted with the same polarity on each side, never allowing it to succeed.  Only if we had a coil that had the same polarity on both sides..  Then we may be able to induct it with the rotor AND the prime mover. 

So I made a small crappy pancake and folded it over like a taco..  Powered it up and tested.  And indeed the same polarity is on either side.

Watch the vid of magnet test- https://www.youtube.com/watch?v=usvt_B-sEXM

If it has a magnetic field when powered, it should induct with 2 like polarities on either side.

I think it is useless as is..

Unfold it and the magnetic strength is much greater.  It would need shielding inside the taco center to prevent it from cancelling out. But then the driver wouldn't make it through the shielding..

I now took two permanent magnets and squeezed them with the same poles with force.
I also got the outer sides of such a double magnet with the same poles.
What is the difference between such a magnet and your "taco"?

A coil can induct and generate, where a magnet can not.
The idea was to make a motor where the stator is wound like a transformer. The secondary would be excited by both the rotor and primary.

Doesn't really matter because the fields start to neutralize on the taco. But the idea was the taco would be a pickup.

Edit-  I tried the idomus model below and achieved about 65% out as opposed to in.  I think if the pickup polarity fields matched, it could have done much better.  and I am pretty sure this is what the synchronous motor in the anonymous schematic is doing here- https://overunity.com/19243/anonymous-schematic/msg570815/#msg570815

 The Alexander  motor in that patent does something similar except the rotor has the two coils. It has one coil to turn the rotor and the other coil is induced and also collects rotation magnetic flux. So if that worked you would see them everywhere by  now.


My crude opinion is a watt of power is a watt of power but it can be enhanced by permanent magnets as in the electric toothbrush and the radiator motor in the auto.

Exactly..   My contention is it does not work well because the pickup coil interfaces with the rotor with the wrong polarity.  The pickup coil essentially receives the same polarity from the rotor coil and permanent magnet at practically the same time. 

Now reverse the motor so that a magnet rotor is spinning and the stator is a transformer.  Replace the stator's secondary with a special coil that has the same polarity on both opposite sides, and now the rotor and primary of the transformer can both induct the secondary properly.

The problem is- the Taco design sucks..  It showed promise until I compared the flux field folded vs unfolded.
