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

[cheors]

"réfléchissez 36 bobine peuvent être relier avec une autre"

My translation as i understand Pierre:
Think again, 36 coils could be (possibility, probability) connected to one more coil (a 37th coil inside the core ?)
Remember the wire(s) going directly to the core not through the 5 green connectors !
And  remember 37 transistors !!

just a thought

Thanks cheros,

you're right, looking at Pierre's French writing again, the word "réfléchissez" is the action of thinking over something which could be translated as "Think about it" or as you wrote "Think again"

You're also right that the word "peuvent" may be more related to the word "could" instead of "can" as I wrote

So I translated :

Fr. et réfléchissez 36 bobine peuvent être relier avec une autre

to En. and reflect 36 coils can be connected with another

but it could also be:  En. and think about it, 36 coils could be connected to one more

Notice I did not add the word coil at the end as he did not write that.

Thanks for bringing this up and you or anyone else is free to point out translation options as it can or should I write could change the outcome,

Regards
Luc

Maybe you could get some good ideas from the next link:

According to that, the key is to distort the magnetic fields in order to bend the magnetic lines and create flux cutting induction. Creating two fields in repulsion is one possible way to distort their magnetic lines and get the wires cut by those magnetic lines.

Who said anything about measuring the common?  How do you account for 10W total input?  Refer to the attached schematic.  This is an example of my understanding of Luc's measurements but using your values.  Using the current flows shown, we consume 1 watt from the supply via the input, and we return 9 watts via the output thru the recovery diode to the supply.  Thee black box is magically generating
8 watts over and above the input consumption of 1 watt.

In1 + In2 = InT... as Recovey goes up, (never to exceed in1 form the powesupply) ... nevemrind just rehashing that point...


The measuements ae the common voltage top of the capcitor, current from power supply, and currrent from recovery diodes.  Power at InT Is not erally measurable because it's thorugh a multitude of bus lines and not from a single source.

Yes, I agree and this is what I was trying to establish and test: https://www.youtube.com/watch?v=WxFxnVld9-8  before winding the coils but I made errors and was way off in my calculations and no one helped since they probably didn't understand what I was trying to do.

Luc, we discussed this before. Based on the measurements you did, your coils have a resistance of 0.53ohm and an inductance of about 0.56mH. When in registration with the rotor, this increases with about a factor of 4, so about 2.1mH.

The time constant of a coil is L/R and cut-off frequency (3dB point) is fc=R/(2*pi*L). Filling in the above values gives fc=0.53/(2*pi*2.1e-3)=40Hz.

Considering your stator steel was probably designed for 50-60Hz, the fc of 40Hz that you have for your coils is not bad. In fact it is in the correct ballpark.

The questions is why we are not seeing more voltage on the output coil. There can be two answers to that:

1. You don't have enough windings on the output coil. Solution: try and output coil with more windings, like a factor of 5 or so.
2. The output rotor is too thick and shorting part of the two neighboring poles when they pass the rotor. Solution: use a thinner rotor.

Or do a combination of both. Hope this helps.
