This tutorial describes how one can use the Ansys Motor-CAD® dedicated electric motor design tool for multiphysics simulation Mechanical module to evaluate the rotor stress distribution in electrical machines.
It gives a brief description of how to set up a Motor-CAD model for a stress analysis, run the simulation and view the results. All calculations are done using the Motor-CAD 2D FE solver.
Learning Outcomes:
Following completion of this workshop, you will be able to:
- Perform rotor mechanical stress analysis in Ansys Motor-CAD.
- Define and configure mechanical material properties for stress simulations.
- Evaluate the effects of magnets, shaft interference, and rotor geometry on stress levels.
- Improve simulation accuracy through geometry refinement and mesh control.
- Assess rotor safety using stress results and yield strength criteria.
- Analyze the impact of operating speed on rotor stress and durability.
Prerequisites:
- Getting Started with Ansys Motor-CAD Software course.
Please note: These training materials were developed and tested in the 2026 R1 release.
