N2 - The topic of this paper is to investigate the achievable performance of the Line-Start Synchronous Reluctance Machine (LSSRM) designed by replacing the rotor of a conventional induction machine. The selected induction machine for the rotor replacement is a general purpose lowpower induction machine. The rotor of this machine is replaced by a rotor of LSSRM. Consequently, the optimization scenario is defined in a way that only the rotor parameters are modified. Objectives are efficiency, power factor and torque ripple of the machine. To reduce production cost, skewing of the stator and rotor is not considered. The optimal geometry of the LSSRM rotor is found by applying an evolutionary algorithm. The considered LSSRM features a rotor were flux barriers and cage bars are located in separate zones. The results of the optimization together with electromagnetic analysis for optimal design are illustrated. The presented approach, which can be adopted for any design of LSSRM, is demonstrating the achievable performance facilitated by simple replacement of the induction machine rotor.
