Abstract

Accurate analysis and optimal design of magnetic couplings are essential to minimise the volume of magnet material and to avoid the construction and testing of multiple models to achieve a given design goal. This paper compares the results of using 3D and 2D finite element analysis (FEA) and analytical methods with experiment. It is found that 3D analysis provides superior agreement. Design of FEA meshes in 3D and 2D are discussed. A method of correcting 2D FEA for end leakage is presented. Optimisation using 3D FEA, combined with computer search techniques, is demonstrated
