Induction motor 2D Identity pair problem

Hi
I'm working on simulating an induction motor in 2D...I've read all guidelines and discussions in forum about electrical machine simulation especially induction one... I tried to model my case in Comsol 5.2 and did all of points and steps carefully but I'm in serious problem about identity pair and magnetic insulation
I tried two way:
1)union rotor section and stator section separately and then assembly and finalize geometry...so generate identity pair automatically...
2)assembly all geometry directly and choose identity pair boundary manually
in first case magnetic insulation apply on identity pair and i couldn't solve this problem...
in second case comsol given an error about that identity pair
could anyone help me...?

Hi Mahdi,
We do suggest you to go through the following blog posts carefully to understand the fundamental modeling approach of rotating machines in COMSOL Multiphysics.
1. www.comsol.com/blogs/how-to-model-rotating-machinery-in-3d/
2. www.comsol.com/blogs/guidelines-for-modeling-rotating-machines-in-3d/
In the next step, you might want to just focus on the 2D models (a full or a sector only) from the following model DB list.
www.comsol.com/model/generator-models-in-2d-and-3d-20191
Note that these examples are for generator, but they should still be useful to correctly setup the identity pairs, sector symmetry etc. in the Rotating Machinery, Magnetic physics.
Hope this helps.
Best Regards,
Nirmal
