摘要

本文对爪极发电机的三维数值模型进行了分析。由于爪极磁路结构复杂，需要采用三维有限元模型和双标量势磁φ-φ红公式，以减少计算时间和内存。计算了电机的空载特性、磁化特性和电动势时间依赖性。在考虑定子的情况下，通过了解转子连续位置的磁场三维分布，可以计算出静态绕组的工作特性和感应电压。

Computation of the characteristics of a claw pole alternator through the finite element method

The paper presents the analysis of a 3-D numerical model developed for a claw pole alternator. The complex structure of the claw-pole magnetic circuit required a 3D FEM model and a double scalar potential magnetic φ-φred formulation, in order to reduce computing time and memory. The no-load and magnetization characteristics and the e.m.f. time dependence have been calculated. Working characteristics and the induced voltage in the static winding can be calculated by knowing the 3D distribution of the field in stationary magnetic regime for successive positions of the rotor considering the stator.
