Basic Study on Magnetically Levitated Conveyor System Using Field-Cooling Magnetization and Pulse-Field Magnetization

Magnetically levitated conveyor system using superconductors is discussed. The system is composed of a levitated conveyor, magnetic rails, a linear induction motor (LIM) and some power supplies. In the paper, pulse-field magnetization is applied to the system from the upper superconductor surface. Then, the levitation height and the dynamics of the conveyor are controlled when the conveyor stops. The static and dynamic characteristics of the levitated conveyor are improved by using pulse-field magnetization.
