hey guys!
there seems to be more interest in motor conversions lately (that is great) and some of you are even attempting to rewind their own stators (thats great also).
the most common motor stators are 36 slot(for 3 phase) (slots are where the coils sit)
if you are going to attempt a rewind, actually, 12 pole would be the simplest to wind in my opinion as the coils are all the same size and multiple coil spans are not used.
it is the most poles you can acheive for a 36 slot stator, and will give you a better chance to successfully feed a transformer if that is your intent, as you would have 60 cycle at 600 rpm.
i am trying to establish a standard way for all of us to help each other when looking for rewind and connection information. i think most of us at one time did a nice painting by numbers, and i think using a numbering system would be the easiest way of how to connect the stator winding.
i have drawn a picture of a complete 12 pole winding inserted into a 36 slot stator (stator plate drawing courtecy of RonB). at first glance you will think WHOA! LOL
just look at it one phase at a time and you will see how simple the coils are spaced and numbered out. the easiest way is to insert one phase at a time, number it and then continue on with the other 2 phases. in the end, you pick your connection you want and happy soldering away you go. the coil end numbers in the diagram do not represent what the numbers of the actual lead wires will be. they are merely a way to find the correct magnet wire end to go onto a specific lead wire that will lead to the connection box on the motor.
for now, this is just where to insert the coils and how to number the coil ends. in a few days, i will start to give you all the possible connections you could apply to this winding. and just a note, if you wanted to go to all the work and actually bring out all the coil ends as leads, you basically could have a unit that would be connectible for just about any battery voltage charging system or use it for high voltage heating.
Attention administration: i purposely left the single pic a little on the large size as it shows the small lines better )shoot me later if you want ;)

Thanks to wdyasq [Ron] for the resized picture to replace zubbly's somewhat larger one.
