Abstract: The paper presents an application of the topological derivative and
continuum sensitivity analysis for the optimal design of the permanent magnet
excited machines with the adjustable excitation. In our work we applied a
topological optimization in order to find a general shape of rotor poles
consisted of an iron and magnet part. An essential advantage of the proposed
method is its numerical effectiveness. In order to verify results,
three-dimensional models were developed and thoroughly analyzed. As presented
in the comparative analysis of 3D results, the applied method lead to the
significant reduction of both, the cogging torque and a level of higher
harmonics in the voltage induced in the armature windings.
