摘要
This paper describes a 3.25:1 linear magnetic gear which has been designed and prototyped to meet the performance requirements of an aerospace application. It has been shown that the force capability of the linear magnetic gear is very sensitive to the spacing between the pole-piece rings and that a 5% reduction in the distance between pole pieces may result in a 30% decrease in force transmission capability. It has also been shown that for a given output stroke requirement, in order to maximize volumetric force density, magnetic designs with large airgap diameters and shorter high-speed armature axial lengths would be preferred.
