| Abstract |
This paper presents the optimal design of an outerrotor surfacemounted permanent magnet synchronous motor for washing machine applications using explorative Particle Swarm Optimization(ePSO)Mesh Adaptive Direct Search(MADS). In the ePSOMADS algorithm, ePSO is used for global search, while MADS is employed for local search. Cost and torque ripple are selected as the optimization objectives. The electromagnetic characteristics of the base and optimal models are evaluated using finite element analysis. In addition, the trends in the crosssectional areas of core, coil, and magnets across optimization iterations are examined to elucidate the mechanism underlying material cost reduction. |
