Flux - SimLab Tutorial : 2D SPM Motor Brushless
Altair EmployeeDescription
This tutorial shows how to use SimLab to design and run electromagnetic analysis with Flux solver for electric motors. The studied device, a brushless DC motor with surface permanent magnet, includes the following elements:
- a fixed part (stator) including yoke, slots, and windings
- an air gap
- a movable part (rotor) with surfaced magnets
In this tutorial, three typical transient magnetic analyses are defined to evaluate the motor performance:
- Analysis 1: Computation of the cogging torque
- Analysis 2: Back Electromotive Force
- Analysis 3: Constant speed
Note: The geometry model is built by the Sketch of SimLab
Analysis 1: Computation of the cogging torque
Analysis 2: Back Electromotive Force
Analysis 3: Constant speed

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.
