Abstract :
This paper presents the effect of the non-uniform air-gap on the various characteristics of a 6/4 doubly salient permanent magnet motor (DSPM). Three important cases among the air-gap non-uniformities namely: (i) relative eccentricity between stator and rotor axes; and (ii) concentricity error on one-half and both halves of the rotor (elliptical rotor) have been analyzed for a 6/4-DSPM using the 2D finite element (FE) method.
