Analysis and reduction of magnet eddy current loss in flux-switching permanent magnet machines

The flux-switching permanent magnet machine has permanent magnets on the stator. The magnet eddy current loss has never been addressed in literature and is investigated in this paper by the finite element method. The influence of operation modes, i.e. constant torque and flux weakening control, is considered, and the methods of reducing the magnet eddy current loss are also discussed.
