How to determine brushless DC (BLDC) winding pattern, based on poles and slots?
An updated version of that chart can be found at www.bavaria-direct.co.za. Here it is:-



Based on the legend Colors (by Relph Okon) I am guessing they have been confirmed. It was probably compiled from the results of experimental winds done by several people.

However many combinations can be calculated by multiplying the patterns of those with fewer poles (eg. 4 poles and 6 teeth has the same pattern as 2 poles and 3 teeth), or applying some basic rules. 

The essential rules are that the number of poles must be even and the number of teeth must be divisible by 3. Secondary rule is they must not be equal (eg. 6P-6T) or an exact multiple of same (6P-12T). Best combinations seem to be where they are as close to the same as possible within those rules (eg. 2P-3T, 10P-12T, 14P-15T).
