Based on 3-D finite element method(FEM), the FEM model is built and some electromagnetic characteristics including the armature winding flux-linkage, EMF at no load, winding inductance and so on are calculated. The air gap flux density distribution is analyzed and field control ability is obtained. A prototype machine was manufactured based theory analysis, and the no load phase EMFs and the field control ability were tested. The analysis results show that a good field control capability is validated by experiment . Keywords ：Stator-separate, hybrid excitation, flux-switching, electromagnetic characteristics, FEM
