| Abstract_FL | Aiming at the cogging torque on the slotted structure of the permanent magnet drive ( PMD) , a skewing optimization method was proposed. An analytical method based on Fourier series expansion was applied to obtain the mathematical model expression of cogging torque which was related to magnet ske-wing, and the different effect of magnet skewing parameters on cogging torque was discussed. Finally, based on the objective function of the minimization of cogging torques of the PMD, the optimal parameters of the PMD were obtained by adaptive weight particle swarm optimization ( AWPSO) searching. At last, the finite element method was used to calculate the cogging torque of non-optimized and optimized PMD, and the results verify that the cogging torque can be greatly reduced with this optimization method. |
