Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

Hi Gotoluc,

I am finding that a single coil set outputs a reasonable voltage on the rotor however, when you add additional coil sets, output reduces and input current rises.

I have 4 poles between the coil 5 slot pitch, so  there is a 1 pole gap between poles.

So far, I have not  found an answer to this.

Well, that's interesting!
PmgR is certain there is no bucking coils event in my configuration even though I have 6 slot space compared to 5 slots.
Please have a look at the video I just posted (above post) for a visual confirmation of the coil firring and have a look at the wiring chart PmgR made to see if you can find something that could cause the ridiculously low output. Maybe the Half bridges are conducting through another path?

Thanks and everyones input is welcome. Please have a look TK to see if we are missing something. Keep in mind that 5 coils are powered in series plus one 50% overlap.

If you do have that CH340G serial chip I just found a possible fix for it.  I'll try to attach it here.  I've run it through Virustotal.com also and it is all clear but you can check it too at www.virustotal.com

Again, quoted from my post #386-

All,

To maybe help sort out the the confusion, the 2560 board I shipped to Luc uses An Atmel Mega16U2 as compared to the original Arduino AtMega8u2 for USB communications.

Hi Gotoluc,

I cannot see anything in either your build, or mine causing this problem, so I think my next move is to set up two opposing  poles N&S, positioned across the rotor, initially just one coil each, then just statically pulse them.

I want to see what happens with rotor induction.

Then add more coils in each pole group and check the result.

Yes, I agree! A better plan then rewinding my stator coils to a 5 slot space just to find the same issue
Baby steps for now.

Thanks for coming forward with this.

luc ,

j'ai visionné ta vidéo je remarque que seul 6 led sont actif ,si je comprend bien le schéma de pmgR ,il faudrait 12 contacte actif
par pas ,on dirais que dans ton cas présent 3x10 bobine sont actif au lieu de 6x5 bobine ?

I saw your video I noticed that only 6 led are active, if I understand the diagram of pmgR, it would take 12 active contact by step, we would say that in this case 3x10 coil are active instead of 6x5 coil?
