【摘要】：设计了一种适合于婴幼儿患者应用的磁悬浮心室辅助装置,该装置和通常适用于成年患者的磁悬浮心室辅助装置相比,其器械体积要足够小,故设计了一种微型化轴向气隙磁悬浮电机,并提出采用p±2极算法实现径向位置控制,且通过磁场分析的方法验证了微型化轴向磁悬浮电机径向位置控制方法的可行性。在结构方面:提出的该双定子电机由结构相同的顶部定子与底部定子及一个位于定子中间的悬浮转子构成,其中,双定子结构可以大大减小电机的体积、增大气隙和转矩。在控制方面:转子的转速和轴向位移可由矢量控制方法实现其独立控制,而转子的倾斜量和径向位移可通过提出的p±2极算法实现,由此表明所设计的电机外径为28 mm,高为41 mm的轴向气隙双定子电机可实现其在五个自由度上的完全控制。
[Abstract]:A magnetic levitation ventricular assist device is designed for use in infants and young children. The device is small enough to be used in adult patients. Therefore, a miniature axial air-gap maglev motor is designed, and the p 卤2 pole algorithm is used to realize radial position control. The feasibility of the radial position control method is verified by the method of magnetic field analysis. In terms of structure, the double stator motor is composed of the top stator and the bottom stator with the same structure and a suspended rotor located in the middle of the stator. The double stator structure can greatly reduce the volume of the motor and increase the air gap and torque. In the aspect of control, the rotation speed and axial displacement of rotor can be controlled independently by vector control, while the tilt and radial displacement of rotor can be realized by the proposed p 卤2 pole algorithm. It is shown that the axial air-gap double-stator motor with the outer diameter of 28 mm and the height of 41 mm can be fully controlled at five degrees of freedom.
