基于ANSOFT公司Maxwell 3D软件仿真环境，建立了汽车用爪极电机的三维模型，详细介绍了该模型的三维有限元建模方法、分析步骤与过程，给出了瞬态电磁场的有限元分析结果，并对仿真结果进行了分析验证。%3D model of the claw-pole alternator used in the automobile was established based on the Maxwell by the ANSOFT Company. The 3D modeling method, analysis steps and procedure by means of the finite element method were introduced in detail as well as the result of the finite element analysis of the transient electro-magnetic field. The simulation result was analyzed and verified.
