The Design of Low-Cost Synchronous Reluctance Motor with a Surrogate-Assisted Optimization Technique

This paper presents the performance of centrifugal pump coupled with synchronous reluctance motor of 24kW. The 4-pole 36 slots induction motor stator has been used for the prototype. The reduction of torque ripple and power losses is the main aim of research. Different arrangement of rotor flux barrier shapes has been tested through finite element analysis method. The rotor optimization is done by varying different parameters are used such as, barrier edge angle, width of flux carriers, flux barriers and shaft diameter. In order to improve the motor performance, the method of particle swarm optimization has been used by generating samples with surrogate assisted optimization technique. Distinct flux barrier shapes and designs have been checked through simulation. For the prototype development, final V-shaped best model is chosen. The proposed rotor shows the excellent performance in terms of reduced torque ripple (27%) and improved average torque (154Nm) in experimental results. The suggested design also has good thermal and mechanical performances with the capability to use in various industrial applications.
