摘　　要：微型轴流式血泵是目前人工心脏结构研究的热点,外磁驱动是一种新型的血泵驱动方式。本文介绍了血泵外磁驱动电路的设计。该电路能够产生双向励磁电流,直接驱动电机,实现血泵的外磁驱动。电路简单、实用,稳定性较好。Minisize axial flow blood pump is the focus on the structure study of artificial heart recently. Being driven via outside magnetic field is a new driving method on blood pump. In the article, the design of outside magnetic driving circuit of blood pump is introduced. The circuit can create bi-directional current, which can directly drive the motor. Therefore to be driven via outside magnetic field is realized. The circuit is simple, practical and stable.
