Motor-CAD can automatically transfer geometry, material properties, excitations, and boundary conditions to Maxwell for electromagnetic analysis. Electromagnetic results from Maxwell can be imported into Motor-CAD for efficiency mapping and thermal analysis over duty cycles. Motor-CAD geometry can also be exported to ANSYS Workbench and CFD tools like Fluent to enable detailed flow and heat transfer modeling to validate and calibrate Motor-CAD's convection formulations. Links between Motor-CAD and ANSYS multi-physics software simplify and expedite complex motor design simulations and analysis.

5. 5
• Motor-CAD and Fluent CFD complement each other
• In Motor-CAD it is fast to create models and solve
• CFD is more time consuming to construct models and
make calculations
• Useful to filter designs using Motor-CAD and do CFD on
final candidate
• Then use results to calibrate Motor-CAD convection &
flow formulations
• Assistance in CFD model setup using links to Motor-CAD
being developed
• Speed up the creation of CFD models

Detailed flow modelling using Fluent CFD can be used validate/calibrate the
convective cooling around the end-windings due to air movement induced by
rotation

Automatically pass the thermal resistance network from Motor-CAD to Icepak for the
main body of the machine
Solve the main body of the motor in Icepak as a thermal resistance network and the
housing cooling system as a CFD problem
Allows extremely fast combined lumped circuit/CFD simulations times
