项目摘要
Purpose of this research project is to establish small and high power efficient magnetic suspended motors for artificial heart. Three type of magnetic suspended motor have been studied.1.Radially suspended motor, which suspends the rotor in the radial direction, has been studied for a fundamental research of a maglev pump for an artificial heart. The maximum rotating speed, the maximum head pressure, and the maximum flow rate of the developed maglev pump were 2400 rpm, 310 mmHg, and 10 L./min, respectively. The plasma free hemoglobin was 13 mg/dl and the hemolysis property was enough low as an artificial heart.2.Axially suspended motor, that a levitated rotor is set between top and bottom stators and suspended in the axial direction, has been studied to clear basic characteristics of a suspended motor with control in five degrees of freedom (5-DOF). The radial control mechanism was added to this motor and the 5-DOF control suspended motor was constructed. The 5-DOF control suspended motor, which can rotate up to 3200 rpm, has been developed successfully and a basic design method of the 5-DOF control suspended motor was established.3.A miniaturized magnetic suspended motor with 5-DOF control has been developed for an axial flow pump. An impeller is suspended by a set of hybrid magnetic bearings at each side of the impeller. The motor stator is set between the magnetic bearings. The length and diameter of the suspended motor is 92 mm, 48 mm, respectively. Maximum torque is over 10 mNm under a rotational speed of 10000 rpm. Maximum rotating sp0eed with complete levitation in the air was 16,000 rpm. The total power consumption in the usage condition was 12 W and enough low for implantation. The micro suspended motor for an axial flow artificial heart has been developed successfully.
本研究目的在于建立小型化、高功率效率之人工心脏磁悬浮马达。本文研究了三种磁悬浮电机:1.径向悬浮电机,将转子沿径向悬浮,是人工心脏磁悬浮泵的基础研究。研制的磁悬浮泵的最大转速、最大压头和最大流量分别为2400 rpm、310 mmHg和10 L。min,分别。血浆游离血红蛋白为13 mg/dl,溶血性能足够低,可作为人工心脏。2.研究了轴向悬浮电机,即悬浮转子置于上下定子之间,沿轴向悬浮的五自由度悬浮电机。在此基础上增加了径向控制机构,构成了五自由度控制悬浮电机。成功研制了转速可达3200 rpm的五自由度控制悬浮电机,建立了五自由度控制悬浮电机的基本设计方法。3.研制了一种用于轴流泵的小型化五自由度控制磁悬浮电机。叶轮由位于叶轮每一侧的一组混合磁轴承悬挂。电机定子设置在磁轴承之间。悬浮电机的长度和直径分别为92 mm和48 mm。在10000 rpm转速下,最大扭矩超过10 mNm。在空气中完全悬浮的最大旋转速度为16,000 rpm。在使用条件下的总功耗为12 W,足够低的植入。研制成功了轴流式人工心脏微悬浮电机。
