摘要
研制了一种新颖的永磁轴承,由两个大小不同、充磁方向相同的同心磁环组成。将这种永磁轴承应用于叶轮式全人工心脏的结构设计,现已完成了样机制作和初步测试。耐久性试验已经持续14个月(进行中),血泵流量和压力没有任何变化,电机驱动参数如电压、电流及转速也没有任何变化,表明泵内没有机械磨损。
A novel permanent magnetic bearing has been designed,and used in an impeller TAH(total artificial heart)in the aulhors' laboratory.The endurance test has lasted 14 months(on going)and neither pump flow or head nor motor driving parameters such as voltage and current as well as speed has changed.That means no mechanical wear has occurred
