This paper presents three-dimensional boundary element analysis for coupled magnetic field and moving problem. The method is applied to improve transmission characteristics of a magnetic gear and the usefulness is demonstrated. The gear has two movers consisting of permanent magnets and they rotate with different velocity. The double gap moving problem is very time consuming, because the mesh has to be regenerated at each time step or prepared many patterns previously. The use of the boundary element method is suitable for this problem, because meshes are required around only surfaces of considering objects and the objects can be rotated any angle according to the moving simulation. In this paper, the technique to reduce unknown variables in the boundary element equations utilizing symmetrical construction is proposed.
