Abstract: Effect of the manufacturing and assembling imperfectness on the performance of synchronous reluctance machine (SynRM) was analyzed in this paper. Based on an optimized SynRM, the influence of the punching burrs, material partial damage caused by punching, interlocking dowels, riveting errors and the eccentricity of stator and rotor on the average torque, torque ripple, efficiency and radio force was detailed. Through the analysis of these influence, this paper concluded the processing techniques which should be controlled strictly during the manufacturing and assembling of the SynRM.
