Sector Modeling for Motors

Electric motors often have a form of symmetry or repetition that can be exploited in simulations. When this is the case, a fraction, or sector, of the motor can be simulated to save time and computational resources. The number of sectors is determined by the greatest common denominator between the number of poles and the number of slots. You can then divide your geometry by the result to find the sector size. The sector can then be configured so that the physics, continuity, antiperiodicity, mesh, and results align with expectations.

Watch the video below to learn the details about modeling motors with sectors.
