摘　　要：针对传统轴流式磁悬浮血泵存在轴向尺寸偏长,不利于植入问题。提出一种将无刷直流电机与径向磁悬浮轴承集成结构,可有效缩短血泵轴向尺寸;在讨论血泵结构的基础上,重点通过对无轴承直流电机进行理论计算,获得其设计参数,然后采用数值仿真,讨论了电流、位移以及转子位置角对无轴承直流电机径向悬浮力的影响关系。Aiming at the problems of overlength axial size and implantation difficulty of the traditional axial-flow maglev blood pump,we designed an integrated structure with BLDC and radial maglev bearing,which could effectively reduce the axial size of the pump. We analyzed the design parameters of the bearingless motor by theoretical calculation,then carried out numerical simulation to analyze the effects of the electric current,the displacement and the rotor position angle on the radial levitation force of the bearingless motor.
