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

Hi Luc,

In your stator only has 30 slots, you need to check how the current windings are positioned to see if you can even re-use them.

You will need an even number of poles, so 5 poles won't work (you would end up with NN or SS next to each other). You could make six poles by having the windings span five slots. Looks like that is pretty much the only option as 3 poles spanning 10 slots wouldn't work (odd pole number) and 5 poles spanning 6 slots won't work either (odd pole number). 10 poles spanning 3 slots would be a possibility as well. However, note that the more poles you have, the less "stair case" points you will have per sine cycle, so I wouldn't go that way as it will not give you a nice sine wave. Hence I recommend doing the 6 poles spanning 5 slots each.

I know that and agree with you!   when I'm video recording I often mix up words like say amps when it should of been watts. So in this case I should of said a 5 slot span will fit in the 30 and not 5 poles will fit in the 30
As for using the existing wire. It can definitely be done but it takes a lot of time. If I decide to take that route I'll make a video to show how I do it. Hopefully I'll say the right words to describe what I'm doing lol.
Thanks for bringing this to my attention and making it clear for others,

Regards

  Well it seems I was a bit jumpy about the first video. Pierre, my apologies to you so I guess I get to eat some crow.
@Partzman, you beat me to help out here so cant but thanks much as well.

Now, am I right in finding that each slot has in fact two coils in it. One is reversed to the other when it is powered. Is that how he is gaining the NSNSNS effect?

Anyhow was thinking on how could I figure out how many winds are in the stator.  Would it not be similar to a transformer in a 24V to 125V backup system?

To my humble opinion, when two or more coils are overlapping, meaning that they have a common core area, then the transformer effect takes place. That means if both of the coils (which actually act as two primaries)are pushing a North to the same direction, then the induced currents between each other will reduce the flow of the current from the source (battery or caps bank) to both of the coils. The outcome will be a North of a much lower intensity than when one coil is in action.

Quick note to Luc
Slyder is on the coding part [its what he doo]

has ordered the exact arduino for programming and also said the mentioned propeller would do the Job but overkill
