新型轴向磁场盘式开关磁阻电机的研究

摘要

提出了一种新型的采用三相6/4极结构的轴向磁场盘式开关磁阻电机,与前人研究较多的单相盘式开关磁阻电机相比,定、转子结构更加简单,加工成本更低,便于调速控制,且克服了单相电机不能自起动的缺陷.使用Ansoft公司的Maxwell 3D软件进行了三维有限元仿真分析,并制作实验样机,验证了电机的性能.%This paper proposed a novel axial field disk type switched reluctance motor ( AFSRM ), which has both the merit of SRM such as simple and robust structure, easy to control and the merit of disk machine such as short shaft, high torque/inertia rate. Comparing with the single phase AFSRM fully researched before, the novel AFSRM has simpler rotor and stator structure, and lower manufacturing cost. Since the novel AFSRM has 6/4 poles, it avoided the weakness of single phase AFSRM, inability to self start-up. In this paper, three-dimensional field and torque analysis of the novel AFSRM were carried out using Maxwell 3D, a 3D finite-element analysis (FEA) software. In addition, a prototype of novel AFSRM was made to validate the design and test the performance.
