【摘要】 对一种磁力驱动器建立了实体模型和2D磁场有限元模型,系统地进行了耦合磁场力学二维分析与研究,推导出2D磁场转矩方程.通过磁场结构参数特性的分析,得出了外磁体厚度为4～8mm、磁隙空气层厚度为2～4mm等重要数据,为磁力驱动装置的优化设计提供了理论依据.更多还原

【Abstract】 The entity modeling of one type magnetic driver was made,and the finite element modeling of 2D magnetic field was presented.The dynamics of 2D coupling magnetic field was analyzed and studied;the equation of torque on 2D magnetic field was induced.The structural characteristics of parameters on 2D magnetic field were analyzed in a comprehensive way.Some important conclusions of the thickness of the outer magnet and the thicknese of air in magnetic gap were obtained,thus providing a theoretic basis for the optimized and design of magnetic driving devices.更多还原
