Ansys Motor-CAD Highlights
Ansys Motor-CAD users can now explore more motor technologies and fully assess the impact of advanced loss effects in the initial stages of electromechanical design.
What’s New
The 2025 R2 release boosts axial flux motor design accuracy with enhanced multi-slice equivalent linear modeling (ELM). The improved mechanical module assesses pre-stress and centrifugal forces early to ensure structural integrity, and the improved ratio-based modeling for wound rotor machines enables robust, geometry-aware design exploration.
Axial Flux Machine
Enhanced multi-slice support delivers significantly more accurate design capabilities for axial flux machines (AFMs). Building on the AFM template introduced in the previous release, which supports both single and dual topologies within the electromagnetic and lab modules, this advancement streamlines development and enhances design fidelity.
Pre-Stressed Mechanical Structure Integrity
The mechanical module now enables users to evaluate and compute the combination of pre-stress and centrifugal forces, providing critical insights into structural performance early in the design cycle. This capability empowers engineers to address the mechanical integrity of pre-tension due to rotor banding and press fit between shaft and rotor lamination, driving more robust and reliable product designs.
Ratio-Based Modeling for WRSM
Enhanced ratio-based modeling for wound rotor synchronous machines (WRSMs) enables robust geometric variation during design space exploration. This is crucial for large-scale parametric analyses and design studies, and it is a powerful tool for ensuring model robustness.
