Introduction to 3D Motor Modeling
Throughout this course, we have covered a number of different motor modeling approaches; however, modeling in 3D adds complexity that you will need to account for when setting up your models. For example, the added dimension will increase the complexity of your mesh. In some cases, you can use swept meshing to help ensure that the mesh is viable and that the model can be solved with your available time and computational resources. Additionally, the coil configuration will often require an analysis of the coil geometry to solve your model in 3D. You may also need to consider the mixed formulation in order for a 3D model to converge. This approach combines the magnetic vector and scalar potentials.
Watch the video below to learn more about these considerations and see demonstrations of 3D motor modeling.
