Abstract :
This paper proposes a simple method to take into account the influence of end-effect on flux-linkage and back-emf in both flux-switching permanent magnet (FSPM) and doubly-salient permanent magnet (DSPM) machines on the base of 3-D finite element analysis (FEA). A leakage factor kend is defined to scale the grade of the influence of end-effect on PM machines.
