Virtually Rotating 4 Overlapping coils

[Jim Mac]

Now that you have the circuit working.
Can you please post a circuit diagram, it will make your system so much easier to understand.
Thanks.. Tom

Sure-  but it's subject to change.  Here is a sloppy paint drawing..  Notice the function generator's leads are isolated to prevent comments telling me the amplifiers are getting ground from them.

You can disregard the transformers output wiring.  I am not convinced that is correct...

Wow..  That was surprising...  I disconnected the 2 amplifiers grounds from each other and the circuit works the exact same!  They don't need ground wires at all!..

I measured current between them and get NOTHING, no AC or DC...

I have a working theory how these amps can work with no grounds...  But I will have to verify...

Jim, I've just been reading over your last few threads to better understand the rotating fields.

Firstly I want to say congrats - you've built a controllable magnet with coils... I'm not sure people realise the magnitude of this.

Anyhow, contentiously I am going to assert that what you've created is the smooth oscillation of field change, but it does not rotate.

If you were to overlay this wiring setup another 3 times, all at 22.5°, then you will have rotation, and smooth oscillation, as the stator will actually be sensing the field rotation. This is the motion that creates CEMF, the field moving across the outputs coils.

But my head is spinning just trying to work out what that would look like.

Yo Uni,  if you review the first few posts of this thread, that build was absolutely rotating in the areas of the overlaps.  Maybe this will next statement will help visualize it..

Say we are using multiple coils to create virtual rotation past 1 output coil,  You would need to view the phase of the output compared to the phase of the coil aligned dead center with the pickup coil.  If you can manage to get the output phase 90 degrees out of phase with the input phase powering the coil at dead center (with resistive load), you ARE inducing like real rotation.  

Because in a standard generator, the output phase lags the rotor by 90 degrees.  Meaning the output sinewave is exactly ZERO when a passing magnet aligns center to a coil face.  

That 4 transformer setup is much more nuanced..  But I believe it's violating the known theories of induction.  The open circuit voltage X shorted current watts (max power potential) well surpasses the input.  Which is not supposed to happen in induction circuits.
