High-speed space debris threatens the safety of satellites in orbit, and efficient removal of space debris has become an inevitable trend. However, the spacecraft is still dependent on the active consumption of propellant to maintain the relative distance in the eddy current brake process. By discussing the high-speed rotating target of non-contact de-spun method and drawing technology, electromagnetic de-spun and drawing technology based on a non-uniform magnetic field is proposed to use alternating current form to control rotate-target magnetic field force during electromagnetic interaction process. Through the simplified model and condition, put forward electromagnetic satellite of one coil control method. The feasibility of the technique is verified by numerical simulation. The simulation results show that the relative distance between the electromagnetic satellite and the target can be effectively affected the output current of the electromagnetic coil controlled through distance feedback under nonuniform magnetic, so as to realize the long-term mission without propellant.
