Lets take that 180W as a worst case, so 180W/21V= 8.57A average  .. 8.57A/12 coils on at any time (assuming overlapping on periods) = 0.71A average per coil.

L192, why are you saying 12 coils are on at any time? Only 6 blue LEDs are on at any time, so that would only be 6 coils on at a time (but 12 relays on to turn those 6 coils on). So current per coil would be 1.42A.

Hi PmgR,

In a previous post, Pierre stated that he switches the next coil on before turning off the previous coil so that makes 12 coils ON.

Yes, that is correct regarding having two coils on at the same time. But look at his blue LEDs: there are always two on next to each other. But total only 6 are on (3 sets of 2 LEDs spaced at 8-10-12 "off LEDs" as mentioned before), so he is switching 6 coils total (not 12) per step. E.g. he will switch the 6 coils in slots 1-2, 11-12, 23-24, then it shifts to slots 2-3, 12-13, 24-25, etc. on the next step.

I have verified that this will generate the six poles NSNSNS that Pierre mentions. I am going to write this up in a PDF with clear images once I have some more time.

I found a parted 2 stroke gasoline AC generator in the lab space I have free use of. So I took it apart to see how many poles (slots) the stator has, see video:  https://youtu.be/iYullLkW9rc
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.
