摘　　要：本文介绍了一种新颖的泵机合一结构的人工心脏叶轮血泵驱动电机的控制系统设计。该控制系统取消位置传感器 ,采用反电势进行位置检测控制 ,结果使血泵可靠性提高 ,性能改善 ,长度缩短 ,连接线减少 ,更适合于临床应用。A new control system of the brushless motor was designed for driving the impeller blood pump. Instead of using rotor position sensor, the peripheral position of the rotor was detected by measuring the inductive voltage in the motor coil, produced by rotor magnets. The results demonstrated that the reliability and performance property of the motor were improved, the motor length and control wires were reduced. It has made the blood pump more convenient for clinical use.
