What's New
The 2026 R1 release advances axial flux machine (AFM) solutions by adding Thermal module support and expanding magnetic and NVH capabilities. An improved induction machine performance map approach with Ansys Maxwell, along with an enhanced Multi-Static with Losses analysis, speeds magnetic and loss predictions − enabling faster iteration and earlier design evaluation.
Enhanced Accuracy and Flexibility in AFM Design
The new Thermal module support (Beta) for AFMs includes blown-over and natural convection, water- jacket cooling, and shaft groove cooling. It also supports adaptive rotor templates, demagnetization methods, a hybrid method for AC loss, and Lab module support, including Ansys Maxwell-Lab link (Beta).
Improved Electric Machine Efficiency Calculation
A unified performance map now supports induction machines with automated Ansys Maxwell–Motor‑CAD integration. Magnetizing and leakage inductance and iron loss Look-Up-Tables (LUTs) improve model accuracy, while automatic steady‑state detection and enhanced Python data‑transfer significantly cut analysis time across all types of electric machines.
Faster Analysis with Enhanced Multi-Static Solver Option
Deliver faster, more accurate magnetic and loss predictions using Multi-Static with Losses option. It is further improved using model symmetry and automatic symmetry detection which reduces setup time. This increase confidence in early-stage evaluations. The capability boosts design throughput and accuracy, improving decision-making and enabling quicker screening and comparison of electric machine topologies.
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.
