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

One of the reasons we have not seen Pierres machine run again, maybe due to relay contacts developing high resistance. This has happened on many of my relays.
Initially they all gave equal coil currents now there is a large variance.
A static test shows the contacts have likely burnt. None were driven over their rating but without arc suppression caps I guess it was inevitable.
Two choices change the relays or back to Half bridges.

Because you use too much Amps. I say that it is not about a large work current that is just minimum.

PC's frequency is correct.  However there is so much more room for improvement.  Wire size and turns will play a big deal moving forward.  It will slap you in the face, once you get it.  It is hidden for sure, and understand why PC has discovered a very important effect.  He has given all the answers in his videos.  Constantly ask yourself questions that relate to a true generator.  If you don't understand true generator basics.  Then you will not get his device.  His very uniquely hidden concept is in every single generator.  Again, which type of A/C generator does PC's device most closely resemble?  Then study it's components and cycles.  Ask yourslef what is your device missing that a normal generator always has.  When you find the answer...it will hit you hard and you'll see that PC is not hidding any truth in his words and videos.

I have no problem in understanding the two basic types of AC generator.The stator distributed windings and wound rotor are similar to a synchronous alternator in reverse, except the stator winding is
energised instead of the rotor.
The big difference is the energisation of whole sections of  the DZ stator windings, whereas the alternator only energises the rotor (DC) which sweeps across the stator windings. For a two pole rotor, every 180 degrees there is a flux polarity reversal. In the case of the DZ generator there are 6 polarity reversals in 360 degrees.
Both generators use distributed windings to approximate a sinewave, although on a 30 slot stator a 3 phase alternator only has to accommodate 3 groups of windings so there is a gap between coils which produces more of a sine rather than a triangular wave.

So Jerdee, why are you so cryptic in your posts, I thought this is supposed to be an open forum?

No the contacts will burn at 3A without capacitors due to the inductive load. Its just a matter of time before this happens.

Just looking at the relay specs,it may be false economy to replace these.
The 10,000 operation life would easily be exceeded in a couple of hours running.
