Interleaved windings 1

[zlatkodo]

We know that in a standard three-phase windings, the maximum number of parallel circuits is equal to the number of poles. By applying the "interleaved windings," we can get more parallel circuits, which is important in high-power, low-voltage machines .
I'm interested in description (advantages and disadvantages) and rules for forming such windings. Also, maybe someone has an example of an internal winding diagram for the interleaved windings?

Correction in bold:
"2 - Concentric approach: 1X22112211X1"
should have been
"2 - Concentric approach: 1X221122X1"

=====================================
(2B)+(2B)' ?

One more thing.
Question of rewinders: If we decide to rewind the motor (from my previous example), in accordance with the rules of the interleaved winding, which is the easiest way to do it in practice ?
Do we need to make a classic 4 parallel circuits (including the 2 coils from each group) or replace each group with 2 paths as shown in the attachment?
In this way we get some kind of partial "equilizing connections", which will not have a bad effect on the winding, I think.

I'm supposed to write: "equalized" rather than "equilizing" in my previous thread.

zlatkodo,
When I used to wind motors I did it the way you have depicted in your attachment.

e-pete,
Great work. I have sent question to EASA, I'll let you know if I get a response.

Thanks
