Investigation of axial field partitioned stator switched flux machines

This paper proposes two axial field switched flux machines with partitioned stators (PS), namely axial field PS switched flux permanent magnet (SFPM) machine and axial field PS wound field switched flux (WFSF) machine. Compared with radial field PS machines, these machines show the advantages of better thermal conditions and more robust rotor structures. The operation principles of these machines are described in this paper. Based on 3-dimensional (3-D) finite element analysis (FEA), the electromagnetic performances of proposed axial field PS machines are investigated and compared.
