Abstract
In this paper, a new brushless doubly fed generator (BDFG) with double stator is proposed. Compared with the traditional BDFG, the winding configurations of the proposed double-stator BDFG are in great flexibility as the power winding and control winding are separately put on the two stators. The double-stator BDFG also has the advantages of increased slot filling factor and improved power density. The asymmetry of the structure and electromotive force in this BDFG is investigated. An improvement is put forward for the double-stator BDFG with segmented structure and this could solve the asymmetry problems effectively. The simulation model is built in finite-element analysis, and the simulation results verify the effectiveness of the improvement very well.
