摘　　要：提出的新型可植入式人工心脏是由轴向磁场结构的永磁同步电动机直接驱动。电机转子安装在人工心脏泵的叶轮上 ,并因电磁轴承的作用而悬浮。文中将重点分析该电机及轴承的结构与设计 ,并给出了一些相关的仿真结果。This paper presents a novel artificial heart, which is directly driven by a compact permanent magnet synchronous motor (PMSM)with axial-field configuration. The rotor of the PMSM is fixed to the pump impeller of the artificial heart, and is levitated by a magnetic bearing. This paper focuses on the structure description, design considerations and analyses of the PMSM and magnetic bearing, and gives some relevant simulation results.
