- Abstract
In this paper, a new method is proposed for design and optimization of a Permanent Magnet Synchronous Motor (PMSM). In this method, the Particle Swarm Optimization (PSO) algorithm is combined with Finite Element Analysis (FEA) and information is exchanged between them online. This information is cost functions and optimization variables. Four parameters that are related to magnets and slots of machine i.e. pole offset, magnet thickness, pole embrace, and stator slot dimension are used as optimization variables in the PSO algorithm, also efficiency and cogging torque are selected as cost functions. In each iteration, optimization variables enter to the PSO algorithm from FEA, then cost function is calculated and results are sent back to the FEA. This process is iterated until the best variables is gained to maximize or minimize the cost function. Also at the beginning, a parametric study is performed on the geometrical dimension of permanent magnets and stator slots to analyze the effects of dimensions variations on efficiency and cogging torque. Permanent magnets and stator slots dimensions are then optimized using PSO algorithm for optimal performance of PMSM. Results of design and optimization show effectiveness and capability of proposed method.
