摘　　要：提出了一种新型的无轴承磁通切换永磁电机,阐述了其结构与径向悬浮力产生原理;通过Ansoft有限元建模仿真,对电机的磁场分布、磁力线、气隙磁密、电磁转矩等电磁特性进行了分析,对径向悬浮力大小与转子位置和电流之间的关系进行了计算。计算结果表明新型无轴承磁通切换永磁电机具有优良的旋转和悬浮性能。A novel bearingless flux-switching permanent magnet（BFSPM） machine was proposed, the topology struc- ture and radial suspension force principle were introduced. The static characteristics were investigated by using the finite el- ement software,including the magnetic flux distribution, radial air-gap magnetic flux density and torque. The radial forces were calculated under varied rotor position and control windings currents. The finite element calculation results show the proposed BFSPM machine has a good suspension and rotation performance.
