Simple Method to Reduce Computation Time in Planar Air-Gap 3-D FEM Non-Linear Problems

Résumé

In the present work, an easily implementable method to reduce CPU time for some 3D FEM problems is presented. A translational displacement between two parts on both sides of a planar airgap is taken into account with a change of coordinates in the airgap region along the z-axis. To achieve this, formulation and post processing are slightly adapted. The proposed method is applied to an academic problem and to an axial electric rotating machine. Results are compared to a usual method. Time saving, ease of implementation and precision on results are really encouraging with a strong reduction of CPU time keeping a low relative deviation. The method could be easily applied to any configurations with planar airgap as axial motor.
