Abstract :
Based on the dq-axis model, the flux-weakening characteristics of switched-flux permanent magnet machines (SFPMMs) with 12/10, 12/11, 12/13, 12/14 stator/rotor pole number combinations and different winding configurations are analyzed by the flux-linkage method accounting for crosscoupling effect. It is shown that the stator and rotor pole number combinations have significant influence on flux-weakening characteristics of SFPMMs. When SFPMMs have the same structures of stator and rotor, the alternate poles wound one exhibits better flux-weakening capability than all poles wound one. The analyses using the dq-axis model are validated by 2D finite element analysis (FEA).
