Maybe possible idea for duplicating effect of Holcomb and others

[Dog-One]

It's good to test with but once I have my rotor wound I'll be looking for a circuit that is simply flipping the polarity of each coil to create the rotation rather than pulsing them.

Here you go.  This seems to work well on the bench.  A new bench by the way, built just for this project.

I'll keep working towards a final PCB if there is any interest.

Hey Maaaaaate! Good to hear from you. Thanks for that. I got distracted playing with my Signal generator on one of the stator coils of my generator on the weekend. That was interesting. Didn't think I'd be able to dimly light 130 LED strip off it at the right frequency. I'll now get back to winding my rotor

Hi Dog-One,


Thanks for your input.  The circuit looks very nice as well as the video.  I see you are planning to pulse 4 coils.  I am wondering what configuration you had in mind for the arrangement of the coils?


In regards to the idea of pulsing the coils with opposite polarity I am wondering why you or Jimboot think that is necessary.  When you pulse a coil with DC one side of the coil is going to be North and the other side is going to be South.  That is why in a motor half of the coil is on one side of the rotor and the other half is on the opposite side of the rotor.  This allows both polarities to act on the rotor.  However depending on the arrangement of the coils applying alternating polarities may be beneficial.  Like a lot of what we do trying different ideas is always worth checking in to.  I will be looking forward to seeing what results you get.


Thanks again for your input,

Hi Dog-One,


Thanks for your input.  The circuit looks very nice as well as the video.  I see you are planning to pulse 4 coils.  I am wondering what configuration you had in mind for the arrangement of the coils?

My focus is towards patent US11336134B2, Figure 23.  What I see there is an inner and outer exciter coil placed on 16 poles where the collector coils (stator) fits in between.  This arrangement looks to have four magnetic quadrants, with the exciter dividing it up into 22.5 degrees per quadrant.  According to Dr. Holcomb, one can expect a COP somewhere between 3 and 5.  Not sure I actually buy into that statement.  I would think one could easily find themselves with a device that is COP < 1, or 2 or 2.5 with maybe a theoretical maximum of 5.  His statement is a little disconcerting to me.  TinselKooala mentioned 1.2 as the goal.  That would be a COP where we have the ability to loop the device; anything greater is gravy and we scale up or out as necessary.

I actually would prefer to have more stator poles.  One reason for this is to shorten the flux path on the outside perimeter.  The other reason is to tighten up the resolution.  What I mean by that is to compress the angles for each tick of the excitor circuits.  So instead of 22.5 degrees per tick, I'm thinking 15 degrees or less would be better, provided I can pack enough windings next to each other on the inner exciter coils.

If we were to use a typical alternator core, I think it has 36 segments.  Then we divide this up by the four exciter circuits.  That gives us nine output phases, which is fine.  I plan on rectifying each of these anyway and dumping them on a DC output bus.  With 36 segments, we have 10 degrees resolution, which is real good, but winding those inner exciter coils is going to be very tight.

Something practical I can actually build would have 24 segments, giving us 15 degrees resolution and six output phases.  I think that will be a sweet spot and I might actually be able to find a core that is close and if not, I'll have to find someone with a waterjet cutter and hope I can find some electrical steel for them to cut.

In regards to the idea of pulsing the coils with opposite polarity I am wondering why you or Jimboot think that is necessary.  When you pulse a coil with DC one side of the coil is going to be North and the other side is going to be South.  That is why in a motor half of the coil is on one side of the rotor and the other half is on the opposite side of the rotor.  This allows both polarities to act on the rotor.  However depending on the arrangement of the coils applying alternating polarities may be beneficial.  Like a lot of what we do trying different ideas is always worth checking in to.  I will be looking forward to seeing what results you get.

Attention to detail.  UFOpolitics did this to me, so blame him if I sound anal retentive.  hehe

Picture the magnetic circuit(s) for a particular set of exciter coils.  Think of the steel in those circuits as being permanent magnets.

Now imagine a shift, one tick of the exciter coils clockwise or counter-clockwise.  Did you notice where a north/south flux became a south/north flux and when that flux change swept across a stator coil?  Did you notice which side of the stator coil it swept?  One side a N/S to S/N sweep produces a positive voltage on the stator coil and the other side produces a negative voltage.  So what we want are two sweeps:  the N/S to S/N on the leading edge produces a positive voltage and the S/N to N/S on the trailing edge also produces a positive voltage.  We want both of those EMFs in-phase and to happen simultaneously.  We have to match our exciter coils and segments to our collector (stator) coils.  I'm pretty sure that's the main concept behind this HES device.  The flux paths just "happen" to cross or cut the collector wires at the right place and at the right time.  These wires get induced an EMF because they experience a localized magnetic flux change.  We know the rest right?  The EMF they produce is shunted by a load that causes them to produce their own magnet field that opposes the change in flux that created the EMF in the first place.  The trick here the way I see it is, in the HES device, this opposing magnet flux (Lenz) assists the shifting of the exciter coils.  It actually starts magnetizing a pole that we were about to magnetize in the same polarity anyway as well as demagnetizing another pole that we were going to have to apply a current to to get a pole flip.  There has to be a slight offset between what we call the rotor and the stator.  This offset has to be tuned to the speed at which we shift excitor coils and the remanence of the steel.  I see this from a mechanical perspective as degrees which is why I think we want tight resolution of the excitor coils.  If we build a prototype where this resolution is too sloppy, we won't be able to tune it and a COP of 1.2 or higher is out of the question.

Thanks again for your input,

Not a problem Carroll.  I really doubted I would be able to contribute anything let alone actually attempt to build one of these devices.

Something I should mention:  I think the digital aspect of this device is important.  You recall all those magnetic motor videos where the inventor went to great pains to overcome the dreaded "sticky spot"?  We have digital switching with this concept.  We can hop right over the sticky spot and we can do it in such a way where we create the maximum pulling force while minimizing the drag force.  I think this equates directly into COP > 1 potential.  That ability coupled with the resolution may be where Dr. Holcomb comes up with his numbers of 3 to 5 times energy gain.  So you might ask, how can this work with a 3-phase excitor?  I'm not certain you can do it with true analog 3-phase, but I bet you could do it with synthesized "digital" 3-phase.  So the experiment you started with in this thread may never show us what we're looking for, but it did provide a lot of food-for-thought on what we can do.

Thanks for being anal Matt and thanks for the contribution. Carroll my reasoning for alternating coil polarities isn't anywhere near as Sophisticated. It's just that is what his original vid showed the rotor doing.


I'm currently distracted with a signal generator, amp and my 1kva stator/rotor. Pulsing the 1ohm coil on the stator I can brightly light a 25watt incandescent off the 8ohm stator coil  and 1wire lighting of a cfl off the rotor coils in series(one hAnd territory) which gives a heck of a belt but low current.
