Annex 1 Winding order and winding function example
A 4-pole, twin parallel winding per phase, 60 slots, 2 conductors per slot and « polarized » windings (i.e. a single winding has all the positive poles while the other has the negative ones, has the following winding order for the
A2 winding.

[09 57 08 56 07 55 06 54 05 53 39 27 38 26 37 25 36 24 35 23]

So the first conductor of this specific winding is located in the slot #9, then in slot #57 and so on. Arbitrarily, the first conductor is defined as a negative conductor, the second as positive, the third as negative, etc.

[09 57 08 56 07 55 06 54 05 53 39 27 38 26 37 25 36 24 35 23
−1 1 −1 1 −1 1 −1 1 −1 1 −1 1 −1 1 −1 1 −1 1 −1 1 ]

Then, the winding order and the conductor signs are sorted.

−1 −1 −1 −1 −1 1 1 1 1 1 −1 −1 −1 −1 −1 1 1 1 1 1 ]

Knowing that in this case a pole is aligned with slot #1 and the winding is polarized, the following winding function is obtained.
