What's New
Ansys Motor-CAD is the result of the relentless pursuit of continuous improvement to provide electric machine engineers with motor designs that are more efficient and easier to produce.
NVH for Wound Field Synchronous Machine (WFSM)
Calculate NVH behavior for WFSM/EESM for the automotive industry. The electromagnetic excitation forces are calculated using 2D FEA and used with analytical mechanical and acoustic models for complete NVH analysis. This enables earlier evaluation of NVH behavior in the design process, saving significant time.
Winding Definition & Analysis
Improved hairpin winding flexibility and feasibility checks, combined with a simplified UI and an automated hairpin layout, can save significant time in model generation. These improvements will enable engineers to explore a more expansive design space by analyzing different winding configurations.
New Cloud Offerings
Motor-CAD is now available on Ansys Gateway virtual desktop. Access to powerful hardware allows Motor-CAD and OptiSLang workflows, and other Ansys tools, to run simultaneously to achieve short product development cycles.
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.

Ansys Motor-CAD connects to Ansys Maxwell for advanced 2D and 3D electromagnetics analysis. For electric machine noise and vibration and (psycho-acoustic) sound prediction, Ansys Motor-CAD integrates with Mechanical and VRXPERIENCE. It also connects with Ansys CFD solvers and leverages air, water and oil based cooling techniques for cooling system design and analysis, as well as provides feedback into the Motor-CAD’s thermal model.
Comprehensive and powerful geometry templates enable the complete electric machine design space to be explored. Templates cover a huge range of electric machine technologies, topologies and cooling systems. Ratio based parameterization options are a new addition which provide unprecedented capabilities for parametric design optimization.
Coupled multi-physics analysis from the start of the design process and in-built control algorithms enables virtual testing considering temperature effects over transient drive cycles or at steady state.
Design of modern electric machines requires performance analysis over the full torque/speed operating range. Motor-CAD enables designers to easily and quickly analyze the performance of their designs over the operating envelope, including field weakening behavior.
Rapidly evaluate designs against the complete multi-physics performance requirements such as peak and continuous torque/speed characteristics.
Any electric machine simulation requires understanding of the manufacturing effects and the impact of variation in the manufacturing process on performance. Motor-CAD has built in knowledge to guide engineers in configuring the manufacturing effects appropriately and enables straightforward sensitivity analysis to understand the impact of manufacturing variation on performance.
Motor-CAD is the ideal tool to use for optimization of electric machine designs. Powerful ratio-based optimization enables the design space to be explored easily while the coupled multi-physics analysis enables evaluation of each candidate design against the complete performance specification.
Automatically extract and visualize magnetic forces as a function of time and space, over the full operating range. Enabling NVH analysis of a design.
Rapid, automatic FEA based rotor stress analysis enables engineers to easily optimize rotor designs and trade-off between electromagnetic performance and mechanical constraints.
