Computation of magnetic forces on moving conductors by using ELEKTRA and other 3-D computer codes

The finite-element computer code ELEKTRA is the only publicly available code known to the authors that is capable of solving 3-D eddy-current problems that entail the use of moving electrical conductors having finite dimensions. It is, therefore, expected to become a standard tool for the analysis of magnetic levitation (maglev) systems using sheet guideways. This study systematically evaluates the ELEKTRA code by comparing it with experimental data and {open_quotes}benchmark{close_quotes} solutions, as appropriate. In addition, alternatives to ELEKTRA were investigated, and a new computer code, based on an extension of the double-Fourier series analysis, was developed.
