ABSTRACT

The paper presents the electromagnetic modeling methodologies of a two-channel limited angle torque motor. There are presented two types of numeric models: two 2D models created by using specialized software for the numeric field analysis COMSOL Multiphysics and FEMM and one 3D model created with COMSOL Multiphysics. First, the numeric results for the 2D models will be compared. In the second part, the benefits of the 3D model will be highlighted. Finally, the numeric results of all models will be validated by comparison with the data obtained in the experimental way.
