Abstract In order to reduce optimally torque ripple of transversally laminated rotor in synchronous reluctance motor(TLR-SynRM), a type rotor structure of the insulation of the gradient flux-barrier was proposed. First, using as the insulation of the gradient flux-barrier a starting point and on condition that the linear segments width of each layer of insulation flux-barriers was equal to the circular segments width of each layer of insulation flux-barriers, and the mathematical relationship between structure parameters and torque ripple was derived. Second, on the basis of the design of the analytic method, it analyzed the relationship of the structure parameters and torque ripple by the contour maps combined with finite-element method(FEM) and provided a reliable basis for Taguchi's method to select the standards. Once more, it built the experimenting orthogonal by the Taguchi's method and obtained the optimized parameters' rules of selection. Final, according to the scheme proposed in this paper and a prototype motor was designed. Both FEM and experimental are verified the optimal design scheme is feasible and the type rotor structure of the insulation of the gradient flux-barrier can effectively reduce torque ripple.
