Magnetic Suspension System with Large Distance of 82 mm Using Persistent Current in Superconducting Coil

Superconducting techniques are applied to a superconducting magnetic suspension system. A coil, copper coils, magnetically suspended object, photo sensor, PID controller, and power amplifiers the main components of persistent current in coil control coils used for suspending object controlling respectively. This paper discusses large gap trial system, static dynamic characteristics system studied. As result, it is found that continues be at distance 82 mm more than 60 s. Since has maximum limit 50 adopted. The details studied performance There few reports about such with 80 using current.
