Abstract :
A new two-dimensional adaptive meshing technique for the analysis of rotating machines is presented. The method preserves the symmetry and periodicity of the meshes during adaptive refinement. This allows for a more accurate calculation of the cogging torque than the standard adaptive meshing scheme. The advantages of this method are demonstrated by results for a surface permanent magnet motor and a permanent magnet motor with pitted teeth.
