Modelling of sleeves and calculation of the eddy current losses

[benedict284]

Dear development team,

I am excited to see the opportunities, which pyleecan is giving me as a machine designer. I am currently looking into high-speed permanent magnet machines. Due to structural reasons a retaining sleeve is mandatory in these applications. The sleeves are not necessary to have for the magnetic performance calculation, but the eddy current losses caused in the sleeve are important to be determined.
I have tried a couple of things to use the class of SIPMSM machines and go for the UDMachine and two rotors (one internal as magnet and one external as sleeve). For the approach with the UDMachine I get to the point that I can define the geometry but I am not able to start a simulation. As definition a "lamination list" was used. Is there a tutorial how I go from there to define the stator and rotor objects? I think in your tutorials you go to the point of the geometry creation with the lamination list, but not further to the simulation with this machine class.

As you see I have three major questions:
1.) Would you go the same route? Or do you recommend a different approach?
2.) Is there any advantage or disadvantage in going this route? Or is it easy to integrate a sleeve somehow into the SIPMSM class?
3.) Is there a tutorial on how to run a UDMachine? If no, I would appreciate your support and I will create a tutorial from that.

For a better understanding I share picture of the cross-section of a machine.

With kind regards,
Benedict
