Ansys Motor-CAD

Electric machine design

Ansys Motor-CAD is a dedicated electric machine design tool for fast multiphysics simulation across the full torque-speed operating range.


Make electric motor design decisions quickly and with reliability

Motor-CAD optimizes motor designs for performance, efficiency, and size by enabling engineers to evaluate various topologies and concepts across the operating range. Its integrated modules (EMag, Therm, Lab, Mech) facilitate quick and iterative multiphysics calculations, accelerating the journey from concept to final design.

  • Intuitive, template-based set up
  • Full operating range design
  • Built-in em, thermal and mechanical solvers
  • Thermal sizing of machines
