Modeling Magnetic Cores in Transformers and Electric Machines using COMSOL Multiphysics® - Archived
Evaluating core characteristics and losses is a crucial part of the design of electric machines, transformers, inductors, and other magnetic components. Accurate time-domain modeling of core materials is achieved using the Jiles–Atherton (JA) hysteresis model available in the AC/DC Module, an add-on to the COMSOL Multiphysics simulation platform.
Moreover, the JA model allows for the incorporation of coupled effects such as magnetomechanical effects and anisotropic effects into its formulation. Advanced versions of the JA model, considering dynamic losses and other factors, can be formulated using the mathematical interfaces provided in the COMSOL Multiphysics software. This webinar will delve into the background of the JA model and demonstrate its application in formulating the characteristics of core materials for transformers and magnetic devices.
