Although lately I've been using this one as it's on the university computers.
I did find and play with emetor and also Koil, and some demo versions of others, but really my only requirement was no of turns per slot and I did not find that these gave me that info.

I originally tried the forum in the hope that some kind soul would help with some positive info.

It is highly unlikely that I will wind another motor, this was a just a whim that became a challenge.
