Concentric windings with different number of turns

[tcaja]

Hi all,

I am curious how to go about defining a concentric winding where each coil nest (or coil group) is made up of a number of elemental coils, each with a different span and different number of turns:

It seem that the various winding class will only allow a fixed number of turns (Ntcoil parameter).

Any insight would we appreciated!

Hello,

Thank you for your interest in pyleecan. If I understand correctly your drawing, normally you should be able to simulate that by defining a WindingUD with 3 tangential layers (Maybe you will also need to define a SlotUD2 to draw the correct layers) and in the wind_mat property you can set a different number of coil turn per layer. You can refer to the following guideline for the winding matrix: https://pyleecan.org/winding.convention.html

Sadly I don't think that we have a validation case for that, if you manage to simulate your machine do you think that you can share your results so we can add a new test ?

Best regards,
Pierre
