My code attached. No refinements or attempts to reduce lines.
Not tested yet.
I have another version for a 36 slot stator, as I have a 10KW motor coming my way.

Ah... OK.... But...

1. Your code doesn't compile, because of a minor error: you left off the closing curly bracket in loop(). Once this is fixed the code compiles and runs... But...

2. There is a timing irregularity. This was also there in the original sketch Pierre proposed and I don't recall ever getting a straight answer about whether this was intentional on his part (the "Secret") or a mistake (the "bug"). At any rate it interferes with the smooth flow of the fields around the stator. To be specific, there are two "delay" intervals between "Enable_1x, HIGH" and "Enable_1x, LOW" and also between "Enable_10x, HIGH" and "Enable_10x, LOW", whereas there are three "delay" intervals between all the other "Enable_" HIGH and LOW statements. If this is intentional, fine, but it would be nice to know why.

3. It is far better IMHO (for debugging and actual running, since the desired loop speed is so low) to include setting the "delay" interval value each time it is used, via the potentiometer, rather than setting it once per loop. So I'd recommend replacing each "delay(x)" statement with "delay(map(analogRead(A0), 0, 1023, 0, 100))" so that the speed can be set without having to wait for the loop to finish. This adds some tiny microseconds to the execution time but compared to the "60 Hz" output speed this is insignificant.

4. In my testing it looks like this code has several more "overlaps" than previous versions. That is, instead of just two LEDs lit at any time, this has groups of 5 or 6 chasing around. My test board doesn't have all 30 LED positions populated though; I am only looking at the first "thirdrant" of the complete circle (Pins 1 - 12) , so I'm not seeing the full picture in my hardware test.

To shed some more light on the coil winding pattern from Pierre, I went back to my old post:

For Pierre's case, I think we need to get clarification from him how exactly he has wound the stator. What I assumed in my latest simulations is that a coil runs over 7 slots and the next coil is in the neighboring slot (see my number sequence above).

01-07 08-14 15-21 22-28 29-35 36-06
07-13 14-20 21-27 28-34 35-05 06-12
13-19 20-26 27-33 34-04 05-11 12-18
19-25 26-32 33-03 04-10 11-17 18-24
25-31 32-02 03-09 10-16 17-23 24-30
31-01 02-08 09-05 16-22 23-29 30-36

36 coils total, so he could be using this winding configuration. The magnetic field pattern is attached (7SlotCoilSpan).

Yet he could also have done it like this: spanning 7 slots and have the neighboring coils in the same slot, then he would get the following sequence:

01-07 07-13 13-19 19-25 25-31 31-01
02-08 08-14 14-20 20-26 26-32 32-02
03-09 09-15 15-21 21-27 27-33 33-03
04-10 10-16 16-22 22-28 28-34 34-04
05-11 11-17 17-23 23-29 29-35 35-05
06-12 12-18 18-24 24-30 30-36 36-06

This actually yields the same coil configuration as the previous configuration (yet in different order, but that doesn't matter).
So again, 36 total coils, so he could be using this configuration.

So let's look now at a coil span of 6 slots instead of 7:

01-06 07-12 13-18 19-24 25-30 31-36
02-07 08-13 14-19 20-25 26-31 32-01
03-08 09-14 15-20 21-26 27-32 33-02
04-09 10-15 16-21 22-27 28-33 34-03
05-10 11-16 17-22 23-28 29-34 35-04
06-11 12-17 18-23 24-29 30-35 36-05

Again 2 coils per slot and 36 coils total, so he could be using this as well. I note that his one has his magic number sequence 01-06 ; 02-07; 03-08, etc. see post #170. For the magnetic field, see the attached image (6SlotCoilSpan).

Let's see if he could have done it like this: spanning 6 slots and have the neighboring coils in the same slot, then he would get the following sequence:

01-06 06-11 11-16 16-21 21-26 26-31 31-36
36-04 04-09 09-14 14-19 19-24 24-29 29-34
34-03 03-08 08-13 13-18 18-23 23-28 28-33
33-02 02-07 07-12 12-17 17-22 22-27 27-32
32-01

However this only gives 29 coils, so he can't have used this.

Someone should ask him what he is using.

I've "massaged" listener191's code a little bit to get rid of the timing glitch (assuming it is unintentional), fix an error in comments, add the realtime speed control, etc.

I haven't been able to figure out how to compress the 10 coil-actuation statement sets into a single loop yet, but I'm sure it can be done.

Please, Stefan or moderators... can you enable the "code" BBTag?
