I'm working on a 20 Pole generator and this is what I've come up with so far.
On a 20 pole 30 slot it would look something like this
1 2 3 4 5 6 7 8 9 10 11 12 13/14 15/16 17/18 19 20
N S N S N S N S N S N S N S N S N S N S
A a A a A a A a A a
B b B b B b B b B b
C c C c C c C c C c
For each pole pair that's 360/10 = 36 deg per pole pair
On the stator we have 30 slots so 360/30 = 12 deg per slot (thus 12 * 10 = 120 deg)
And 36/12 = 3 thus on entry is phase A North B is 50/50 between North and South and C is South

On a 20 Pole 15 slot
1 2 3 4 5 6 7 8 9 10 11 12 13/14 15/16 17/18 19 20
N S N S N S N S N S N S N S N S N S N S
A a A a A
B b B b B
C c C c C
For each pole pair that's 360/10 = 36 deg per pole pair and 360/20 = 18 degrees per pole.
On the stator we have 15 slots so 360/15 = 24 deg per slot (thus 24 * 5 = 120 deg)
And 36/24 = 1.5 so that means we have 1.5 phases per pole pair
Thus our A phase is a full 18 degrees in North(1) and 6 degrees in south(1) B is 12 degrees in South(1) and 12 Degrees in North(2) C is 6 Degrees in North(2) and 18 degrees in South(2)
Am I right so far?
Now how is this wound? Do I pick a direction and wind in the same manner and same direction. Then connect like connections. Would it be sufficient to say if I wind counter clockwise on all coils and say positive is left and negative is right and stay consistent with it it would work? My rut is that I'm at the winding stage confused if I should switch winding directions...
