摘　　要：提出一种新型的轴向叠片各向异性转子无轴承同步磁阻电动机,并将该电机与传统凸极转子无轴承同步磁阻电动机进行了悬浮特性对比分析。分别详细论述空载和负载条件下两种转子结构电机的悬浮运行原理,给出了样机设计参数,并对上述两种无轴承同步磁阻电动机的悬浮力进行有限元计算与分析,证实轴向叠片各向异性转子无轴承同步磁阻电动机能更加有效地产生悬浮力和电磁转矩。A novel type of bearingless synchronous reluctance motor（BSRM） with axially laminated anisotropic（ALA） rotor structure was proposed,and suspension characteristics in BSRM with the ALA rotor and with the conventional salient pole rotor were analyzed.Suspension operation principle of the BSRM with two types of rotor structure was presented at load and at no load.The motor parameter was given and suspension forces in the two types of the BSRM were calculated and analyzed with finite element method.The result shows that the BSRM with ALA rotor is effective in producing torque and suspension forces.
