A quick guide to the software links between Motor-CAD and ANSYS. Provides an easy work flow to Maxwell and Fluent.

1. Motor-CAD Links to ANSYS
Software

2. 2
• All the information
required to make a
calculation in
Maxwell is passed
from Motor-CAD
• Geometry, material
properties,
excitations and
boundary conditions
are automatically set-
up

3. 3
• Electromagnetic data can be imported from Maxwell to create
efficiency maps and calculate performance over duty cycles.

4. 4
• Motor-CAD 3D Geometry exported into ANSYS workbench through
Design Modeler

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
Motor-CAD and Fluent

6. 6
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
Motor-CAD/Fluent Calibration Example
Fluent Correlation for Convection

7. 7
Path Lines Static Pressure
• Fluent CFD can be used to study the water jacket heat transfer &
pressure drop in great detail and used to validate/calibrate the
correlation models used in Motor-CAD

8. 8
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
