Stresses in the lamination of an Interior Permanent Magnet rotor of an electric machine (motor)

    • tic303bd

      I am trying to determine the stresses in the bridges and center posts of an  Interior Permanent Magnet Rotor rotor at operating speed. When setting up the contacts for this problem I have to have at least one bonded contact between the magnet and the lamination in order to ensure solution convergence. However, this does not reflect reality. To better model the stresses I would like to implement all contacts between magnets and laminations to be frictionless. This, however is giving me convergence issues.

      Can you please share the snapshot of the setup? Also, what is the error message with frictionless contact? Can you try a frictional contact with low coefficient of friction?
