摘　　要：该文采用三维有限元方法对 1 台 28V, 35A 汽车用爪极发电机进行了计算,用迭代的方法计算出稳态时额定负载下电机内三维磁场的分布, 然后用能量摄动法计算出负载时电机各绕组的电感值,并给出负载时电机的相电压波形。其结果对爪极发电机负载性能和参数的计算以及爪极发电机的优化设计具有一定的参考意义。In this paper, the calculation of a 28V, 35A claw- pole alternator is done using three dimensional finite element method. The three dimensional magnetic field distribution in the alternator under steady-state rated load conditions has been computed by an iteration method. The inductance values of the alternator windings under load have been obtained by an energy perturbation method and the phase voltage waveform of the alternator under load has been shown. The results of the paper are helpful to the computation of load performance and parameters of the claw-pole alternator and to the optimal design of the alternator.
