Design of Electromagnetic Docking Device for Micro–Nanosatellite

Abstract

In this paper, a kind of micro–nanosatellite electromagnetic docking device is designed and a configuration of electromagnet with iron-core is proposed. Compared with the coreless coil, the electromagnetic force within the docking range can be significantly increased. To resolve the problem of limited capacity of electromagnet attitude correction, a type of taper hole–taper rod matching mechanism is designed to limit non-docking axial motion for docking in electromechanical coordination. Through the ground experiment, the function of electromagnetic docking device is verified.
