RADIAL FORCE CHARACTERISTIC ASSESSMENT IN A NOVEL TWO-PHASE DUAL LAYER SRG USING FEM

Abstract

This paper investigates the radial force characteristics of a novel two-phase dual layer switched reluctance generator. The proposed generator consists of two magnetically dependent stator and rotor layers, where each stator set includes four salient poles with windings wrapped around them while, the rotor comprises of two salient poles. In this paper, the radial and tangential force components and their trends in healthy condition under difierent load levels are assessed with the respect to critical rotor positions. One of the most important problems seen in the industrial applications of generators which have concerned users is the rotor eccentricity which may conclude the unbalanced distribution of ∞ux linkage as well as acoustic noise and vibration due to the radial forces produced during the rotation of machine's rotor. In this regard, in this paper, it is attempted to obtain and evaluate the radial force components resulted from difierent degrees of eccentricity faults.
