Can someone(everyone?) share some specs about their coils?  What is the resistance of a drive coil?  how long is it? how many turns? what is the measured inductance (without the pickup core)?  what gauge wire?


how many strands can fit in one of those slots?  (Yes, more for higher gauge) so...

You can find it here:  gotoluc,   listener192,  r2fpl, ariovaldo and my posts.

Thanks.  You can right click on the link-title just above the 'reply#' and copy the link.

Edit:
according to...
http://hyperphysics.phy-astr.gsu.edu/hbase/Tables/wirega.html
500 feet of gauge 10 wire would be 0.5Ohm.
Is that 0.526K Ohm?  Hmm no; because you'd need 20,000 feet of 24ga wire...

Jeg, " at 120Hz  can be used for sync" .  Agree. This is an odd connection with thin wire. Just a signal current?    About the freq. just leave that 
 Has it to do with the current consumption to his big transformer during charge and under operation?

My pics showing Volt and Amp with the Microwave Oven   OFF  and   ON.

Does anybody know "APME" the label on the Micro Oven?  A company??

Thats just an inventory label. Its a GE MO.

This is the model.

@41lbs This has a 60Hz line transformer.
The power 1500W @13A.

Hi listener192
It's good you found the exact model of MO and that it really consumes 1500 Watt. After all Pierre seems to have produced 60 Hz despite that low 4Hz -->12-15Hz repettion frequency. But We can't  figure that out.
How??

But my question was about that sticker at top rigt hand side. "APME-MICR-029".

Regards Arne

Why are you concerned about a sticker that has been applied, that is obviously not a GE applied item?

I was just curious about Pierre and Pierres possible connection to a company.

Just interested of his background and from where he got his skills

reading in the past 'magic numbers'
the pairing is more like in this image as opposed to opposed...
there was also an early magnet simulation by pmgr would like to see that with a wider pitch on the poles... (n/s of fields separated by 60 degrees Nevermind found here, and here) .  There was a later supposed animated gif, but I couldn't get it to animate even in VLC.

And Re the diodes... 72 diodes. 72 relays, 1 feed from diode board to + .  No - (negative is on the other side of the coil/relay)   - -> relay -> (fork to diode) -> coil -> positive.  (electron current from - to +, when the relay opens, it wants to keep pulling - from the diode/relay side, which will pull eventually against the positive voltage).

But I don't really know how actually 2 relays + 1 coil = reversable coil... this scheme works, if either one or the other relay is activated, power causes a magnetic current.  But, when both are open, there is just a free-wheeling current in the coil and the diode does nothing...  Other ways I tried to hook it up, the diode ended up in parallel with the coil, which again ends up in a lossy short-circuit loop in the coil...

So I suppose each coil is charged...
I haven't finished going through the middle pages (20-40 and 1-20)

I saw that 'pairing' diagram a few time... and while it's true that 1 and 6 are pared, and then 6 and 11 are paired, this does not mean that 1 and 11 are paired.


I colored paired coils (in a span, it's incorrect, span should have been 5, but this drew better) ... so when 2 is on because it's paired with 33, it's the opposite polarity from when 2 is on and 7 is it's pair.....
I highlighted under each with blue and red indicating the poles of the pairing.  The blue is always to the left of the red.
Doing the stepping better would have shown the rotation better....


(other 'fixed') but should be parallel not series...

Image with pitch of 5 marked.  (for 36 coils).  pitch = ( ( coils / 6 ) - 1 )  ; although you can re-sequence it and use just 2 poles...
(too bad it was so late after  Reply #395 on: March 21, 2018, 05:43:39 PM »    "In Pierre's 36 slot he obviously has 6 coils or slots per pole and you can clearly see in the picture below his center core is exactly 6 slot wide."  ... yes, but that's because 2 coils are on at a time so it's (coil-slots + 1) = 6 (the width of the core)

No, there is only a positive return to the super caps.

Yes you are right. Hadn't notice that.
