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.
MOTOR-CAD CAPABILITIES
Integrated Multiphysics Analysis Software for Electric Motor Design
With decreasing development cycles, motor designers need to make design decisions quickly, and with certainty that they will not face problems down the line. Fast calculations and streamlined data input processes leave time for Motor-CAD users to explore more motor topologies and fully assess the impact of advanced loss effects in the initial stages of a design.
Motor-CAD software’s intuitive, template-based setup and embedded multiphysics expertise simplifies the design process and reduces reliance on multiple teams for specific electromagnetic, thermal or mechanical experience — so motor designers can keep more control over their designs.

Multiphysics Optimization of Electric Motor NVH Behavior
Noise, vibration, and harshness (NVH) are essential aspects that must be considered when designing and optimizing a motor. Using Ansys Motor-CAD with Ansys optiSLang, we show how to optimize the motor’s noise alongside the motor’s electromagnetic, thermal, and mechanical requirements. As the design matures, structural information from Ansys Mechanical can improve the rapid analytical structural model, increasing the fidelity of the solution while maintaining the speedy solution times that allow fast design optimization.
