摘要
爪极发电机磁场呈典型的三维分布,需用三维数值方法计算。文章采用三维瞬态有限元法计算爪极发电机电磁场,得到各项铁耗;采用场路耦合法计算,得到了额定负载时电励磁爪极发电机的效率,并且得到了电励磁、混合励磁爪极发电机的最大输出功率。电励磁爪极发电机输出性能实测值与计算值的一致性验证了计算结果的有效性。
For the three-dimensional（3-D）magnetic field distribution of the claw-pole alternator,a 3-D numerical method is required.The iron losses of the alternator were obtained by using a 3-D transient finite element method.Using the field-circuit coupled method,the efficiency of the electric excitation claw-pole alternator under the rated load was computed,and the maximum output power of both the electric excitation claw-pole alternator and the hybrid excitation claw-pole alternator was computed.The measured results of the electric excitation claw-pole alternator verified the effectiveness of the computation results.
