摘　　要：为提高大间隙、高转速条件下磁力传动系统的可靠性,以双T型电磁体为例,分析了大间隙磁力传动系统空间磁场耦合机理,利用ANSYS软件,仿真了电磁体在NS、SS、SN和NN等四种状态时空间磁场的分布规律,并通过实验验证了空间磁场仿真模型的正确性,找到了双T型电磁体作为主动磁极时与永磁转子在空间的最佳安装位置,为轴流式血泵等永磁转子获得较大的驱动力矩提供了依据。In order to improve the magnetic drive system＇ s reliability under the condition of large gap and high speed, the rela- tionship between the magnetic pole state of active magnetic pole （electromagnet） and the running state of passive magnetic pole （permanent magnet） was analyzed, taking the T electromagnet as example. With the software ANSYS, the magnetic induction strength and distribution law of the four states such as NS,SS,SN and NN were calculated. Through vast experiments, the simula- tion model of the space magnetic field was proved to be correct and the optimum installation position of the initiative magnetic e- lectromagnet and the permanent electromagnet rotor was found, to provide a foundation for axial flow blood pump to gain the maxi- mal driving torque.
