The following tutorials use SimLab with the Flux solver for the modeling and analysis of a 2D electric motor. 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.

Step 1 - deals with the motor geometry and mesh construction with Simlab sketcher.

• All the necessary files (zip file): 2D SPM Motor in SimLab - Part 1 - Modeling.zip

Step 2 - deals with motor physics definition and solving process for the following cases:

• Cogging torque analysis
• Back EMF analysis
• Constant speed analysis
