Design Optimization of Synchronous Reluctance Motor for Low Torque Ripple

The aim of this paper is to optimize the design of multiple flux barriers Synchronous Reluctance Motor in order to smooth the torque profile without rotor skewing. A new strategy is proposed by modelling the particular optimal design problem as mixed integer constrained minimization of a suitable objective function. The procedure has allowed to optimize the rotor shape for minimum torque ripple starting from an existing stator core
