Coil test analysis of Wound-field three-phase flux switching machine with non-overlapping winding and salient rotor

Abstract

Topologies for three-phase salient rotor flux-switching machines having DC field winding are presented and coil test analysis, peak armature flux linkage, cogging torque, induced emf and average torque are examined. Salient rotor is used to modulate and switch the polarity of the flux linkage in the armature winding and this is the basic principle of operation of these types of machines. Non-overlapping winding and toothed-rotor are the clear advantages of these topologies as the copper losses gets reduce and rotor becomes more robust. Finite Element Analysis (FEA) is used to examine the three phase topology of proposed Wound-field flux switching motor with non-overlapping winding and salient rotor.
