Ansoft Maxwell -- shaping an interior electric motor rotor

Click For Summary
SUMMARY

The discussion focuses on shaping an interior Permanent Magnet Synchronous Motor (PMSM) rotor using Ansoft Maxwell. The user created a curve-based surface and encountered validation issues, specifically a warning regarding "Eddy effect settings" and an error related to the G3dMesher due to object intersections. Adjustments were made to the band diameter and inner/outer surfaces, but meshing errors persisted, indicating a need for careful management of object intersections in 3D modeling.

PREREQUISITES
  • Understanding of Ansoft Maxwell software for electromagnetic simulations
  • Knowledge of Permanent Magnet Synchronous Motor (PMSM) design principles
  • Familiarity with 3D modeling techniques and meshing processes
  • Experience with troubleshooting simulation errors in electromagnetic modeling
NEXT STEPS
  • Research "Ansoft Maxwell Eddy effect settings" for optimal configurations
  • Learn about "G3dMesher error resolution" techniques in Ansoft Maxwell
  • Explore best practices for "3D object intersection management" in CAD software
  • Investigate alternative methods for "shaping PMSM rotors" in electromagnetic simulations
USEFUL FOR

Engineers and designers working with electromagnetic simulations, particularly those focused on the design and optimization of Permanent Magnet Synchronous Motors (PMSM) using Ansoft Maxwell.

For shaping an interior PMSM rotor from top figure to as in bottom fig, I made an equation based curve, united with another curve , made a surface using coverline and united that shape with my rotor.

When validated it showed band and rotor intersecting and I adjusted the band - DiaGap. Then there was problem with inner and outer surfaces. I adjusted them too. When I validated, got a warning message, "Eddy effect settings may need revisiting due to the recent changes in the design. The default value will be used for the object if the value is not specified". When analyzed, got an error "[warning] G3dMesher Warning - Found 3d objects in Maxwell2D. Model extents are lower left [-1.136000e+002 -4.085621e-014 -4.000000e-003] upper right [1.136000e+002 1.136000e+002 4.000000e-003]
[error] Unexpected error encountered in the meshing process.
[error] Simulation completed with execution error on server: Local Machine."
How can I solve this or is there any another method to shape the rotor.

I have seen this lately, However, i would like to add that G3d mesher problems arise due to intersection of 2 objects. i have found such errors mostly in 3D Modeling.
