Static characteristic of a novel dual-stator hybrid excited synchronous generator based on 3D finite element method

A novel dual-stator hybrid excited synchronous claw-pole generator (DSHESG) is proposed in this paper. The structure characteristics are described and the operation principle is introduced. Using finite element method, the field-control capability of DSHESG is studied. Some static characteristics including air gap flux density, no-load flux linkage, back-EMF, self-inductance of field windings, and mutual inductance between armature winding and field winding are obtained. The analysis results show that the air gap flux can be easily controlled and the power density can be increased effectively. The analysis results agree well with the experiment results.
