英文摘要：

Three dimension finite element model （3D-FEM） of the claw-pole alternator is presented in this paper, and the leakage is analysed in detial. By designing the sample space of the parameters, nonlinear regression modeling of the claw-pole alternator based on support vector machines （SVM） is introduced. Parameters optimization of the claw-pole al{ernator is also introduced which is based on chaos. Simulation results prove that the nonparametric modeling based on SVM is feasible and high efficiency, and it is very fit for the parameters optimization which needs large-scale iterative calculating. Using the integration of FEM and SVM to nonparametric modeling, and parameter optimization based on it provide a novel way for the optimum design of the claw-pole alternator and other engineering.
