摘　　要：为减少无轴承开关磁阻发电机(BSRG)所需功率器件数目,提出了一种将相邻三相定子齿极上的励磁绕组串联的新型发电励磁方式。在详细阐述其工作原理的基础上,从两套绕组的电压方程出发,建立其电流模型,进而结合磁链-电流曲线分析不同发电模态下的机电能量转换过程。根据悬浮力数学模型,提出相应控制策略以实现电机稳定悬浮发电运行,实验结果证实了所提方案的有效性。In order to decrease the number of power devices needed by the bearingless switched reluctance generator, a novel exciting mode in which the three adjacent excitation-windings are connected in series is investigated in this paper. Based on the winding voltage equations, the transient equivalent-circuit model is established and the induced potential is analyzed. After that, the energy conversion process under different modes is illustrated according to the flux-linkage-current curves. Then the control strategy is proposed with the mathematical model developed to simplify the controller. The experimental results verify the proposed method.
