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

I'm exhausted for the night, need rest....but you are thinking.  But again...there is more MUCH more...watch the videos in very slow motion..  Spend time learning generator basics.  For example, what types of generators are there?  There are many, but which one fits his device.  What is the piston to his generator?  What is it in your device that is not giving you this piston?  Think simple....don't over complicate.  Its human to over complicate.   Then ask gain, why is he using roughly 25 volts., I won't say how...I think many see this but don't want to say.


Jerdee.

~25V depends on this secret but it can be the minimum of this device.

But it's really between the caps and the coils... once that power supply is disconnected (even momentarily), it's running through the 4ohm resistor still...

Yes Pierre could have used a diode to bypass the 4 ohm resistor to feed the relays.

Ok. Just a simple question.
If Cap-bank is not feeding something and just lays between the bridge and the collecting coil diodes, then why the bank discharges that fast during transition between main's socket and rotor's output? I mean, if diodes block the charges from either direction while the current that goes to relays is so small then why the bank discharges and so Pierre needs to move very quickly when he changes sockets for a self feeding action?

The cap bank is feeding the relays back through the 4 ohm resistor, when the line power is interrupted.
My point was it doesn't need to pass through the resistor if Pierre bypassed with a diode.Only initial charge current needs to be limited. Attached photo shows my DC power power supply on initial charge. The voltage was set to 25V but the current limiting reduces this to 12.8V. On a linear power supply at 25V, this current would be very much higher.

Listener et all,

  I can not confirm but strongly suggest that your coil slots have to line up with your rotational fields!  PC uses 36/6 = 6 slots, with 30 poles, you are left with 30/6 = 5 slots per winding.  The biggest issue PC is having is his width of the pure field!  The criss-crossing of the magnetic windings does not allow him much options.  This is why he is building a better device.  This is also why we want as many possible slots divisible by 6 on the ROTOR!  If we had a 60 slots on the same size stator, we can then get 60 slots divisible by 6 equaling 10 slots per coil.  We've now created a wider and smoother area to maintain the PURE field.  With the 30 slot rotor, we are doing the opposite, we are losing resolution, which is not good.  This is why the 36 slot rotor is better than the 30 slot system.  But I still believe we can see this effect for sure even with the 30.  Think of it as a digitally controlled rotational field in increments.  I believe we want the highest amount of increments per PURE field.  With a normal generator, the values are infinite, its analog right?!?!

Again, study generator basics. Every one is only seeing one half of the picture.  Again...the rotational field windings is NOT the only answer!!!  I keep saying this.  There is MORE!!!!!

Also, my original thought of using twice the amount of half bridges to strengthen the field is possibly not good!  You will lose something very important.  So the schematic shown below only shows three active half bridges with three more later in overlap.  So only 6 active at any one point in time.   Just like PC.  With his and your relay system using no double throw you have no choice but to keep 60 relays on your system. Which I believe will be fine enough to study the effect.  You will however lose considerable speed and quality of holding the field in rotation with your relays.  This is his hash he is showing in his scope shot.  With half bridges, you can easily smooth this out with a bypass cap.  This is why half bridges have a considerable advantage.  MUCH higher speeds and controlled overlap of the field at these higher speeds.  Higher speeds are important for this device.

Remember this....the STATOR is what makes the current, not the current into the relays.  Your armature output is only colleting the EMF.  I'm certain of this.  Have you asked yourself why PC uses 25V?  And no, we are not braking lenz law here.

Hope this helps,
Jerdee

Hi Jerdee,
I Agree with your first paragraph above.

I have confirmed the induction limitation is purely due to the low frequency using relays. Pierre had another means of increasing frequency.
When you say "study generator basics" and "there is more" are you saying that you know what this is?
