FEM Analysis
Linear-motion electromagnetic systems have been widely studied using electric circuit approach, e.g., [24, 63, 71, 142, 160]. Their operation can be simulated more accurately on the basis of electromagnetic field analysis [48, 101, 173]. Accurate estimation of electromagnetic parameters is very important. The inductance of the stator windings and the propulsion force (thrust) can be calculated from the field differential parameters such as magnetic potential and magnetic flux density distributions.
The finite element method (FEM) analysis allows for calculating the magnetic field distribution in all regions, i.e., air gap, reaction rail, armature core and armature winding. To effectively use the FEM for electromagnetic field analysis, ...
