摘　　要：由于各齿极绕组均独立控制,单绕组无轴承开关磁阻电机(SWBSRM)的容错控制更加灵活,其转矩和悬浮力在故障运行时的补偿方式具有多样化特点。为探究12/8极SWBSRM绕组开路故障下运行性能,本文针对其典型的故障类型提出不同补偿方式,运用ANSYS建模分析其电磁特性。基于有限元分析结果,优化了不同故障类型下的悬浮力补偿方式,为SWBSRM容错技术的理论与实验研究提供参考。Since all of its windings currents are controlled independently, the fault-tolerant control of single winding begringless switched reluctance motor（SWBSRM） is more flexible. The compensation of torque and levitation force in fault runtime has the characteristics of diversification. After clarifying typical faults occurred in the SWBSRM, different compensation methods are developed Meanwhile, the analyzed faults are modeled and studied via the finite element method （FEM）. Finally, the optimized compensation methods for suspension forces are proposed and verified, providing reference for research of fault-tolerant theory and experiment of SWBSRM.
