Modeling and analysis of a Wound Field Rotor Motor
Altair EmployeeDescription
This tutorial shows how to use SimLab to run electromagnetic analysis with Flux solver for electric motors. The studied device, a wound field synchronous motor, is running in motor mode. As presented in the figure below, it includes the following elements:
- a fixed part (stator) including yoke, slots, and windings
- an air gap
- a movable part (rotor) with wound coils
Analysis
In this tutorial, a simple transient magnetic analysis is defined to evaluate the motor performance on load (torque and efficiency).
Results
Isovalues of B
Electromagnetic Torque VS Angular Position
Stator Joule Losses VS Angular Position
Rotor Joule Losses VS Agular Position
Stator Iron Losses VS Angular Position

Note :
The tutorial packaging may evolve with each new version, but not mandatory. The latest version of the tutorial package will automatically work with the most recent release of SimLab.
Example: After installing the SimLab 2025 release, you can find the latest Tuto_2024.zip package. This means that the tutorial has not been updated since 2024 release, that the tutorial does not need to be updated, and that the tutorial still works in 2024.1 release and 2025 release.
Step to follow:
- to follow the example step by step, the corresponding files are in "Example_name_StepByStep" folder containing:
- Input folder: contains initial *.slb databases an other files needed to be able to play manually the tutorial by following the step by step document
- Output folder: empty (contains the obtained results after to play the tutorial)
- Tutorial folder: contains the document describing the example step by step
- to play the tutorial by scripts, the corresponding files are in "Example_name_PlayScripts" folder containing:
- Input folder: contains initial *.slb databases an other files needed to be able to run scripts of the tutorial
- Output folder: empty (contains the obtained results after to play scripts of the tutorial)
- ScriptsTutorial folder: contains script files to be able to play each analysis
