Electromagnetic mechanism property analysis for spacecraft despinning

Abstract

In this paper, the performance analysis of the electromagnetic vortex despinning mechanism based on Halbach configuration is carried out, and the ground test and verification system is designed. First, the main components of the system are introduced: the electromagnetic despinning mechanism and the controllable high-precision and high-speed rotation system. The controllable high precision and high speed rotating system is composed of rotating body, vacuum pump and upper mechanism. Then, different control group and experimental group are designed to conduct ground despinning test with the system, and the actual despinning effect of the designed electromagnetic despinning mechanism is analyzed. Finally, based on the experimental results, the improvement design and optimization direction of the electromagnetic despinning mechanism are proposed.
