170 watts in - 1600 watts out - looped - Very impressive build and video

Hi Erfinder
Just thought about it all again, and I am "pretty sure" the 6 poles Pierre talks about is not how the stators connect!
This is the pattern of the pulsed rotating field.....but I might be wrong about that!!

However,  because in video he says there is "six magnetic fields rotating" I will assume and I hope correctly the 6 poles refer to the NSNSNS pulsing and rotating field pattern pulsed INTO the stator windings....(not the stator windings themselves being "6 pole NSNSNS" - only that they are pulsed like that)

Konehead, you are correct. It's the drive sequence, not the connections. This is how I did the last set of simulations as well and they give exactly what Pierre says: 6 poles with SNSNSN orientation.

Attached is a diagram showing the start point for NSNS operation.

Each of the 36 coils has a controlling transistor and ON/OFF relay.

There are two coil groups x3 North & x3 South each consisting of 6 coils. Each coil has a Polarity Reversal relay which is controlled by the additional transistor (37).

A N or S pole can move in sequence by turning on one of the 6 coils. When the last coil is reached the next set of 6 coils is then used but the coil group polarity is reversed to keep the same pole polarity (either N or S).

In this diagram I have marked the first 6 coils, to show the progression of switching.

Hi Erfinder
Yes why only two pole fixed-rotor pickup winds? Three would be better...Pierre knows this, as my friend and ace engineer Gary Porter "Skipper by the sea" mentioned this to him in one of his youtube videos, in comments section, and Pierre replied saying yes that is correct three pole fixed rotor would create more power and Pierre says he is in process of improving everything and Pierre was also talking about making "flat-bar" shaped fixed-rotor too, instead of the round shaped existing fixed-rotor that he winds circular winds around....I think these comments form Pierre to Skipper is in part two video on youtube.
