摘　　要：介绍了一种可用于人工心脏泵的爪极永磁步进电动机的结构与设计方法。电动机采用AT89S51单片机输出三种波形(方波、正弦波、梯形波)作为驱动激励信号,改变驱动激励信号的频率可以改变该人工心脏泵转子的转速,即可达到调节和控制血液输出的流量及压力。人工心脏泵的结构既适用于离心式人工心脏泵,也适用于轴流式人工心脏泵,可满足生命医学工程领域中的相关实验要求。在无接触的磁悬浮支承下,电动机可以使人工心脏泵获得更优越的性能。Introduced a structure and design of claw-type permanent magnet synchronous motor which can be used for artificial heart pump. Micro-controller unit （MCU） output three waveforms （square wave, sine wave, trapezoidal wave） as drive excitation signal of motor. Changing drive excitation signal can change the speed of artificial heart pump, and can regulate and control the output of blood flow and pressure. This structure can be applied to centrifugal artificial heart pumps, also applied to axial artificial heart pump, and can meet the requirement of experiments in medical engineering fields. With the support of the non-contact magnetic bearing, the motor can make the artificial heart pump have better performance.
