A multi-physics multi-objective optimal design approach of PM synchronous machines

The design procedure of a PMSM includes employing functional models of the machine which reflect the thermal, electrical and magnetic aspects of the machine. In this paper, the complete process for creation of a physics-based model is presented. The model is employed in the heart of the multi-physics design optimization of a PMSM. The design optimization is accomplished by using a genetic-particle swarm optimization process. The design optimization using the physics-based model is applied on a surface mount PMSM. The initial and optimized designs are compared.
