摘要
针对12/8双凸极电励磁发电机的结构特点及工作原理,在二维磁场有限元非线性计算分析的基础上,就气隙变化对发电机的电感特性影响、稳态性能进行了理论分析和仿真验证。分析中考虑了铁心材料的非线性饱和及励磁磁场与电枢磁场间的相互影响,并将稳态仿真结果与实验结果进行了比较分析,验证了理论分析的正确性。
A 12/8 pole prototype of electric exeifing doubly salient (EMDS) generator is designed and calculated using 2-D finite element method (FEM), the inductance characteristic is obtained and analyzed. The influence of the generator's air gap on the inductance characteristic and the output performance is discussed in detail. The effect of the armature field is taken into account. The theoretical analysis is verified by simulation and experiment.
