Dynamic modeling of a newly designed linear actuator using 3D edge elements analysis

A newly designed linear actuator using permanent magnets is analyzed. In order to evaluate its dynamic performance, the coupling between electromagnetic equations is established. Due to the different phenomena involved, analytical procedures cannot provide reliable results. Thus the magnetic forces and other quantities are obtained by 2D and 3D calculations. In order to obtain the 3D field values, edge elements are used; with this type of finite elements, modeling taking into account the permanent magnets is also introduced.
