Abstract


For high speed operation, two new structures of three-phase wound field salient rotor (WFSR) switched-flux motor (SFM), with 24 stator slot and 10 or 14 rotor poles, respectively, are proposed and comparatively studied in this paper.  24Slot-10Pole WFSR SFM structure is superior to the 24Slot-14Pole in the aspects of flux linkage and average torque. Both armature and field winding are located on the stator and rotor is composed of only stack of iron. Non-overlap armature and field windings and toothed-rotor are the clear advantages of these motors as the copper losses gets reduce and rotor becomes more robust. Initially, the motor general construction, the working principle and design concept of proposed machines are outlined. Then, coil arrangement test, peak armature flux linkage, back emf, cogging torque and average torque of both machines are analyzed and compared by two-dimensional finite element analysis(2D- FEA).
