PRODUCT OVERVIEW
Ansys Motor-CAD is a dedicated electric machine design tool for fast multiphysics simulation across the full torque-speed operating range.
Product Features
Integrates with Ansys Maxwell and other physics solvers
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.
Template-Based Electromagnetic and Thermal Design
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.
Electromagnetic-Thermal-Control coupling simulation
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 for Field Weakening
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.
Temperature Dependent Continuous-Torque and Peak-Torque Simulation
Rapidly evaluate designs against the complete multi-physics performance requirements such as peak and continuous torque/speed characteristics.
Manufacturing effects and housing interface
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
Ratio-based optimization
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.
Rotor stress analysis
Rapid, automatic FEA based rotor stress analysis enables engineers to easily optimize rotor designs and trade-off between electromagnetic performance and mechanical constraints.
MODULES
3Fast multiphysics simulation across a full torque-speed operating range
Motor-CAD enables design engineers to evaluate motor topologies and concepts across the full operating range, to produce designs that are optimized for performance, efficiency and size. Motor-CAD software’s four integrated modules—EMag, Therm, Lab, Mech—enable multiphysics calculations to be performed quickly and iteratively, so users can get from concept to final design in less time.
Key Features
Motor-CAD delivers high-fidelity, 2D/3D analysis capability enabling users to analyze end-effects, demagnetization, core loss, hysteresis and other advanced electromagnetic phenomena, calculate the thermal envelope for operation and design complete motor cooling systems.

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.
