Sensitivity Analysis and Design Optimization Methodology for Spoke Type IPMSM Suited to Pump Application

Le résumé fourni par la source

This paper discusses the design of Spoke type Interior Permanent Magnet Synchronous Motors (IPMSM) for pump application. The design of the motor is established as multi-objective optimization considering torque average, motor efficiency, cogging torque and torque ripple percentage as objectives. The design variables to achieve these objectives are determined by geometrical sensitivity analysis. The optimized design is subjected to vibration analysis to ascertain the stress level in the geometry. The results obtained from simulation are in validation with experimental prototype and the closeness of the results justify the design procedure. A comparative analysis of the Spoke type machine with induction and synchronous reluctance motor is presented to highlight its efficacy of design.
