Abstract

An electromagnetic docking device and method based on a high-speed motor belongs to the field of satellite electromagnetic docking. The invention solves the problems of complex structure, long docking time and slow dynamic response existing in the existing satellite docking device. The magnetic docking device of the present invention is composed of the No. 1 electromagnetic mechanism and the No. 2 electromagnetic mechanism used as a pair. Both electromagnetic mechanisms include a high-speed motor, and the high-speed motor is used to drive the docking plate to realize the docking and separation between two satellite modules. . The docking between two satellite modules is realized by two docking disks, two sets of arc-shaped permanent magnets are symmetrically arranged on the two docking disks, and the self-centering effect between the two sets of arc-shaped permanent magnets can realize the two docking disks. The radial alignment and circumferential alignment enable the docking device to have a certain ability of autonomous capture and locking, and the convex and concave surface structure on the docking plate realizes the mechanical guidance of the docking process. The invention is suitable for the docking use of two satellites.
