Ansys Motor-CAD Electric Motor Design Software

Electronics

Ansys Motor-CAD® software’s four integrated modules, EMag, Therm, Lab, Mech all enable multiphysics calculations to be performed quickly and iteratively, so users can get from concept to final design in less time.

Models can be exported to Ansys Maxwell and other tools for high-fidelity 2D/3D analyses using automated workflows.

Electric Machine Design Software

Ansys Motor-CAD is best-in-class electric machine design software with four integrated modules: EMag, Therm, Lab and Mech. They offer fast multiphysics simulation across the full torque-speed range.

Perform iterative electromagnetic, thermal, and mechanical calculations to accelerate from concept to optimized final design.

Export models to Ansys Maxwell or Mechanical for high-fidelity FEA verification via automated workflows.

EMag: 2D electromagnetic performance analysis including back EMF, cogging torque, losses (core, hysteresis, eddy) and automatic meshing for rapid topology evaluation.
Therm: 3D thermal network modeling for steady-state/transient temperatures, cooling design (water jacket, spray, convection) and coupled loss import from EMag/Lab.
Lab: Full operating envelope testing with efficiency maps, peak/continuous torque-speed curves, drive-cycle performance and control strategies (max torque/amp).
Mech: 2D FEA for rotor stress/displacement under centrifugal forces, pre-stress (banding, press-fit) and mechanical limits.

Key Features

Template-based setup for wide range of electric machine topologies, cooling concepts and ratio-based parameterization for parametric studies.
Electromagnetic-thermal-control coupling for field weakening, continuous/peak torque simulation over full envelope.
Enhanced multi-slice equivalent linear modeling (ELM) for accurate axial flux machines (AFMs), supporting single/dual topologies.
Ratio-based modeling for wound rotor synchronous machines (WRSMs) enabling robust geometry-aware design exploration.
Magnetic force analysis and manufacturing effects (housing interfaces) for early NVH and structural insights

Benefits

Accurate Electromagnetic and Thermal Simulations

Ansys Motor-CAD® can accurately simulate the electromagnetic and thermal behavior of electric machines, enabling engineers to optimize their designs for better performance and efficiency while accounting for advanced loss effects early.

Faster Design Iterations:

With Ansys Motor-CAD®, engineers can quickly test and optimize their designs without the need for expensive physical testing using template inputs.

Cost Savings

By optimizing designs, engineers can potentially reduce material and manufacturing costs, and improve the overall efficiency of their products.

Comprehensive Design Capabilities

Ansys Motor-CAD® offers a comprehensive set of design capabilities, including electromagnetic and thermal simulations, coupled mechanical and electrical analysis, and multiphysics simulation, allowing engineers to evaluate the impact of different design choices on system performance.

Integrated Workflow with Ansys Tools

Motor-CAD fits into a complete Ansys workflow from concept to verification: export to Maxwell for detailed electromagnetics, Mechanical for structural/NVH, optiSLang for optimization, and Sound for acoustic perception.

Evaluate radial/tangential/axial forces, pre-stress + centrifugal effects, and “hear” the motor at varying RPMs to refine for human perception.

Supports drive-cycle efficiency, PWM excitation, and surrogate-model optimization for large design spaces.
