Abstract :
A method for analyzing three-dimensional (3-D) magnetic field in a model including moving parts, such as linear actuator, was developed by using a nonconforming mesh with edge elements. In this method, the meshes for moving and nonmoving parts are generated individually, and they are overlapped together at an arbitrary position. Then, the magnetic field analysis is carried out by using the nonconforming technique with interpolation. It is shown that the proposed method is useful for a dynamic analysis of a 3-D actuator model.
