Internal Permanent Magnet (IPM) with Rotor Skewing (Workshop)

This course provides a step-by-step guide to mapping forces from Ansys Maxwell® advanced electromagnetic field solver to Ansys Mechanical™ structural finite element analysis software for an Interior Permanent Magnet (IPM) motor with a skewed rotor. It covers project setup, including HPC configuration, project screening, data import, force calculation, postprocessing, and mechanical integration, ensuring efficient simulation and accurate force mapping for optimized motor design.
