Hi all

Here is link to Lasersabers video done June 9 - he has coils in sereis and "bucking" (cancelling) where they make no juice at all, but when he adds magnets behind cores, now he gets 30ma or so in the dead-short condition (I guess the dead-short is thorugh an ammeter)
it has no effect on draw to motorcoils part of it - you can tell by sound of motor stays steady....this is very promising really...I am sure most of you have seen this already but here is re-post:

Remarkable.
Looking at it at first glance, it just looks like you are shorting out the right coil only which would have the same effect for the current flow than using just the left coil (again, in theory). Simulation of this situation is impossible, simulator goes crazy shows 5 kV pulses and 1.5Amps through the 1 ohm resistor.
I will try to test that coil set-up on the bench then and make some measurements.

EDIT: I connected a series bifilar that sits on one coil in the way described and no sine waveform. I compared all situations.
What was your load after the FWBR? I simply shorted the DC side.
When i remove the center tap coil short to AC leg and the left coil interchanging, there is no change in the waveform, indicating that the short completely excludes the right coil (shorted out).
Since i don't have a rotor where i can easily put 2 coils up and down, i can not test the opposing coils situation.
This situation can possibly be different, just reporting what i tested with a series bifilar.
Maybe some more people can test this center tap short to one side of FWBR AC?

Hey Xen:

I don't rememeber exactly which DC side situation I had. But as far as I remember it was not important. Standard setup was one or multiple coilpairs paralleled and going into cap. Eventually connected to a load.
All of my generator coils are bifilar adding. But I wouldn't consider that important either.

I tested this when resembling Romero's waveform. I came to the conclusion that it's showing current because it was matching exactly.

Hey chamaladad

OK the FWBR was round so thought it was top view of cap at first glance should of looked some more - was wondering about the AC terminals! (duh!)

If there is pure sinewave across that 1 ohm resistor (not 10ohm eh?) then that IS quite remarkable like Xenomorph just said.

Its also nice thing that the simulator goes crazy...whatever circuit works OU and lenz-less in generator coils is not going to function in any simulator that is for sure.

I will try to test this "center tapped" FWBR out in next few days in Romero-like thingies I built and see what happens with it.

Maybe hook up double FWBRS, and the other pulls out from other side too at same time or staggered in time a bit with different resistance or different diodes in caps (??) - seems like the logical next step is a couple FWBRS,,,,interesting that Romero had double FWBRs too, with smaller diodes rimming bigger-amp inner ones.

Q:
Did you have the magnets behind the cores in there too when you got the pure sinewave??

Hey kone,

It says 1 Ohm on the picture, you must have taken the O for an 0. My BRs are round, don't blame me for that. Glad you've worked it out. ;-)

This was not related to magnets. When I had the hard ferrite cores installed the magnets would not be effective much anyway. I got iron dust cores now and am currently replacing my rotor shaft and bearings so I cannot test right now. But it should be easy to resemble if it isn't core material specific.

In my earlier testings with the hard ferrite I could get over 200V peaks when shorting the coils in a way like this (but maybe not exactly like this). I posted that and it was not considered being unusual. Shorting with a reed switch the voltmeter was showing around 90V constantly. I am not sure if it's core or rotor distance related. My iron powder cores are stronger so I cannot get too close to the cores. That's one reason I am replacing the shaft and bearings.

About the hall alignments, I show it on the image posted here.

@wattsup: Has anyone accomplished to inverting the driving circuit?

Not that I know of. I am still convinced that AOAO will be one of the best ways to provide maximum torque along with cascading coils and will try it myself when I eventually make my own wheel. But not a Romero wheel. It will be my own design with drives on the outside and generator coil on the inside of the wheel. But not yet. Still to many questions to answer.

I posted something that may interest you and others also, here.

Rod over at the energetic forum also reports a slight rotor speed increase when he introduces a constantly shorted out generator coil.
What is special in his set-up is that he overspeeds the rotor (>4000 RPM)

@Konehead: You are right, Lasersaber's video went nearly undiscussed.

If the magnets are in a constellation that they reduce the nearby coil's inductance in the same way , so that both coil's still have a nearly equal inductance, then that is indeed strange, since the coil's should still have equal opposed induction qualities.

I tend to believe though that he increased one coil's inductance and reduced the other coil's inductance (the orientation of the magnet dominates that, i tried it).

The effect of the "no-slow-down" is most valuable.
I wonder if he overspeeded his rotor as well ? (>3600 RPM)
