摘　　要：用场路结合方法计算一种新型汽车用爪极发电机系统效率。和普通电励磁爪极发电机相比,混合励磁爪极发电机提高了效率。有限元方法虽然计算精度很高,但计算时间很长,不适合计算效率。给出一台混合励磁爪极发电机三维等效磁网络模型,在磁场计算的基础上,由电路分析计算各种损耗得到混合励磁爪极发电机系统的效率。The efficiency of an automotive claw-pole alternator system was computed using a field-circuit method. The hybrid excitation claw-pole alternator has a higher efficiency than the electric excitation claw-pole alternator. The finite element method requires a large computation time, so it is not appropriate for computing the efficiency. A three-dimensional magnetic equivalent circuit model of a hybrid excitation claw-pole alternator was proposed, On the basis of magnetic field computation, the efficiency of the hybrid excitation claw-pole alternator was computed.
