Abstract :
In this paper, it was proposed to the optimization of skew of SPMSM with 3-dimensional finite element method (3D-FEM). The optimization technique was used multi-step parallel Genetic Algorithm (GA) and the allocation of material assignment method. As a result, in useful computation time, It was able to obtain an optimal skew special shape. And, it was able to reduce the cogging torque of more than 97%.
