Modeling Electric Motors with COMSOL Multiphysics^®

---

In this self-paced motor modeling course, you will have the opportunity to walk through several examples of motor models. You will start with an overview of motor modeling capabilities in COMSOL Multiphysics^®. In the first lecture, we will cover the fundamentals of 2D motor models, which can be created and solved relatively quickly due to their limited complexity and computational resource requirements. In later parts of the course, you will learn to debug your motor models and make use of sector modeling for more efficient computation. More complex models will be discussed when we cover the Motor Tutorial Series from the Application Gallery. The last two parts of the course will address time-periodic motor modeling and the details of 3D simulation, respectively. Along the way, you will be provided with materials you can reference and use to further expand your knowledge.
