摘要

提出了一种线性管状开关磁阻电动机。该驱动器是专门用于左心室辅助装置(LVAD)。为了避免血栓形成，该执行机构包括泵和阀门功能。通过在管状动器内使用圣犹达医疗机械阀，在降主动脉中产生脉动流。建立了基于磁阻网络的作动器基本模式线性模型。然后进行了二维有限元分析，对解析计算的性能进行了校核。在这两种型号的基础上，讨论了该类电机设计的具体要求。

Linear tubular switched reluctance motor for heart assistance circulatory: Analytical and finite element modeling

A linear tubular switched reluctance motor is presented. This actuator is devoted to be used as a left ventricular assist device (LVAD). In order to avoid thrombosis, this actuator includes pump and valve functions. By using a St. Jude Medical mechanical valve inside the tubular mover, a pulsatile flow is created in the descending aorta. A linear model of a basic pattern of the actuator based on a reluctance network is developed. Then, a two dimensions finite element method analysis is performed in order to check the analytically calculated performances. Relying on these both models, specific requirements for the design of this kind of motor are discussed.
