Oh come on if one man takes a day to a job how many  men would i need to do it in an hour ?

by sharing the load and organizing the timing !

I dont think you understand AG

36 - coils.... 36 slot stator, slot sharing is necessary to accommodate number of coils.
36 - transistors for controlling relays, 2 relays per transistor....
72 - relays....  2 per coil...

In order to complete one AC cycle,each paired relays have to switch on and off once.
We have 60 AC cycles per second(60Hz),and so each relay pair would have to switch on and off 60 times per second-->that is once every 16.6 milliseconds --not going to happen.

His relay noise should sound like the below---dose it?

Watch this video of his in full screen HD.
Watch the iron filings very closely
Do they look like there jumping around at a 60Hz frequency?--no way.

How many wires should be going from the stator to the relay bank?-->36 live + 1 common at least.
Dose it look like there is 37 wires in the lume from the stator to the relay bank?--see pic below.

Also,it is a wonderful feat to achieve exact mains line frequency and voltage using mechanical relays.

Possible ON time to relay X? (No!)

Until someone comes up with a better relay principle (timing), that makes the relays  able to work, I'm hesitant that Pierres Contraption works giving OU as shown in the movies!

A repost from Pierre at the moderated topic 

Here is the latest from Pierre


"The only concern I have are the mosfet's you use, I'm not sure if they will withstand the the input amperage? just a single coil takes a lot of amperage, check before how much one coil draws compared to the 2 amps the mosfet's can handle.

Well I have to argue that very strongly. Todays motor controls of just about every kind is done via transistors(mosfets mostly) from the tiniest toy drones to the controllers to drive electric bicycle hub motors to electric cars. Im working with some mosfets that are 1.4mohm on resistance and can handle gobs of current compared to the relays. Can run .2ohm loads at 4v, 20 amps continuous and the transistor barely gets warm, no heat sink. But i do use a sink to be rid of as much heat developed for max performance. 3034 mosfet.

Ive seen some very small surface mount mosfets that are just amazing(to me) as to what they can do, and no heat sink needed. If any of you do the vaping instead of smoking cigs, if you have a chance to take apart your hand held vape device, you will see what Im seeing. these are used as a buck/boost converter to drive the vape coils and have digital power adjustments.

Not to come down on Pierre but I think his thinking on this needs to be corrected.

 Hello all,

I just spotted this thread and I was following Pierre's videos. Just I missed long discussion, wow!

For Pierre - great job! I always dreamed about creating rotating magnetic field without moving magnet or coil and you just did it!..
For Luc and other builders - great job on taking interest and trying to assemble setup. Now need to finish your rigs for actual testing if you still have spare time.

Here are my thoughts for breaking down whole thing into building blocks:

1) To make induction we have to alternate magnetic field. Without moving magnets or coils we only can achieve that when adding or removing power from additional electromagnets. Then have neutral point and polarity reversed when going around circle with switch on/off groups. This is also reflected in given numbers from Pierre. Which are 36 electromagnets with 6 poles. Which breaks down to 6 electromagnets per pole (5 active and 1 switched off to give space between poles as per Pierre's explanation video).
2) By activating 1st then 2,3,4,5th electromagnets we increase and decrease magnetic field strength so we can alternate resulting magnetic field in the core inside of stator. Which makes induction as the magnetic field strength changes.
3) When shifting starting coil number we simulating moving magnet poles
4) As the electromagnet is not treated like transformer primary we spend all current on plain wire resistance when each coil is activated. Which means when we put load on or off on the center core coil it does not lower electromagnet inductance any more as we relay on coil wire resistance already.
5) By collecting BEMF after each coil is switching off or getting induction from neighbour coil we recover partial energy back to the bank of super-capacitors.
6) The generated power is looped back to the input and the excessive power is taken to the load.

Now to my questions and things required to test so we can understand exactly what is going on:
1) On the BEMF/inductance recovery.  Luc and others - can you try to power on coils in the sequence I mentioned and see what amount of power is getting to recover? This defines overall COP of the system before we start talking about induction part. This is very important so we will know how much power in percentage is required to make system self running.
2) How much power you can induce after smoothing over shotky HV diode bridge and high voltage cap?
3) If COP of the system before looping back is less than 70% - do we miss any crucial steps when making magnetic field increase/decrease in 6 steps resolution? Like too long duty cycle on coils or something like that...
4) Would Pierre elaborate on my post and give some comments on his view of the whole thing?

So, any volunteers for making tests?

 Cheers!

Mags, ikr, as they say. It really is a bit of a different situation if you are used to swapping FET's on RC stuff.
I can vouch for the A49T SMD MOSFETs, blew a factory fitted FET on an Eachine EO10 micro quad and the ridiculously powerful but cheap replacement is still running a year later. Altered another to run with 8mm motors with no issues and those things can draw 2A.
5.8A capable, likely with a heatsink plate of copper stuck on top with superglue or something. Or superglue a penny on top of it   
Probably older design regular sized FET's are what he is referring to, but i've ordered the N-channel A49T and P channel A19T's.

Hey Slider.  Good to see you around here.

This thread has been amazing for me to read.  The ignorance exhibited here is really fun to watch.  If most of the people posting their excitement about a rotating magnetic field would have taken the time to do a little research about how AC induction motors work they would have known already that they work because they all have a ROTATING MAGNETIC FIELD.  That is what makes the rotor ROTATE.  I am not talking about any other motor than the AC induction motor.  DC motors operate entirely differently.  As a side note, Tesla was the first person to visualize a way of making a motor operate from AC with a rotating magnetic field.

Now I am not saying that Pierre's device doesn't work.  I am only saying that a rotating magnetic field is not something magical.  The way that Pierre is doing it MAY have something to do with the results he is getting.  Or maybe not.  I would love to see a rotor similar to his inserted into a normal AC induction motor and just supply it with the normal rotating magnetic field that would be there.  For those that have access to 3 phase power the results may be very interesting.

Someone suggested his results might be because of the phase shift caused by the rotor not being in full contact with all of the stator coils.  The normal AC rotating magnetic field should not be any different in that respect than the rotating magnetic field produced by all that elaborate circuitry of Pierre's device.

Respectfully,
Carroll

Hi Cifta,

Yes there is nothing magical about a rotating magnetic field alone.

Pierre has already stated  in the moderated thread, that there is something else that we can't see/have not seen, that is required to get the result he obtained.
This something he will not reveal to us.

Hello all,

I just spotted this thread and I was following Pierre's videos. Just I missed long discussion, wow!

So, I did read 41 pages of thread (mostly) and noticed it started going off the rails since page 30(typical as always). I would like to give a pinch for putting back to what was all about.

For Pierre - great job! I always dreamed about creating rotating magnetic field without moving magnet or coil and you just did it!..

Ahhh!   I knew we were still missing one of the great minds on this thread.   Glad to see you here T-1000!   Unfortunately due to some nonsense being flung around we may need to figure out a couple things here Pierre has opted out of sharing after he saw the bad behavior.  However I think between the coil winding info and the Arduino code he shared that some of the most difficult parts have been given out here and in Gotoluc's moderated thread on this device.   I think the 'piston power' he mentions as being the missing part may be related to how power is handled between the super caps and the system.
